[U-Boot-Users] gunzip question about large uImages
by Robin Getz 13 Mar '06

13 Mar '06

Quick Question: It looks to me that the max uncompressed image size is hard coded to 4Meg (0x400000 bytes). Any thoughts why? Long question: We were having some problems booting large uImages (reported here ~ month ago). It seemed as if the were not being decompressed properly. When we had someone (Aubrey Li) dig into it he found/pointed out that in the latest cvs, u-boot/common/cmd_bootm.c the function do_bootm defines what looks to be a uncompressed max length as: uint unc_len = 0x400000; This is passed to gunzip if the image needs to be uncompressed. --snip-- case IH_COMP_GZIP: printf (" Uncompressing %s ... ", name); if (gunzip ((void *)ntohl(hdr->ih_load), unc_len, (uchar *)data, &len) != 0) { puts ("GUNZIP ERROR - must RESET board to recover\n"); SHOW_BOOT_PROGRESS (-6); do_reset (cmdtp, flag, argc, argv); } break; --snip-- gunzip takes this as the second parameter and sets it to dstlen. int gunzip(void *dst, int dstlen, unsigned char *src, unsigned long *lenp) This is passed to the inflation routine as s.avail_out = dstlen; where inflate from u-boot/lib_generic/zlib.c uses this to halt decompression if the image size can not fit. -- snip -- from int inflate(z, f) -- if (f == Z_PACKET_FLUSH && z->avail_in == 0 && z->avail_out != 0) r = inflate_packet_flush(z->state->blocks); --snip -- from local int inflate_flush(s, z, r)-- /* compute number of bytes to copy as far as end of window */ n = (uInt)((q <= s->write ? s->write : s->end) - q); if (n > z->avail_out) n = z->avail_out; if (n && r == Z_BUF_ERROR) r = Z_OK; /* update counters */ z->avail_out -= n; z->total_out += n; -- When unc_len is increased - our problem goes away... So: two questions: - what is the best way to manage the size of unc_len? in include/configs/platform.h? Or just make it really_really big? - do you want a patch in u-boot/common/cmd_bootm.c/gunzip to check to see if the image was completely decompressed? OR - do you want a patch in u-boot/lib_generic/zlib.c to return an error if it runs out of room? Thanks -Robin

[U-Boot-Users] Why exceptions are enabled before exception vector code is copied
by Cedric VINCENT 13 Mar '06

13 Mar '06

Dear Wolfgang. Can I ask you why exceptions are enabled before exception vector code is copied to the low RAM pages ? (I am talking about U-Boot/PPC) On my board, U-Boot crashes before relocation (when debugging) since Xilinx Microprocessor Debugger (XMD) makes a spurious "Machine Check Exception". For other reasons, such an exception could arrived before u-boot starts. Finally, it is a bug or a very strange coding behaviour... Cedric VINCENT.

[U-Boot-Users] [PATCH] I2C2 support for MPC8548CDS
by Zajac Adam-AAZ004 13 Mar '06

13 Mar '06

The attached patch adds I2C2 support for the MPC8548CDS board. I've performed a limited testing on our MPC8548CDS board and everything seems to be working fine. Since this processor is brand new, I may need to revise the changes when we build our real system based on '8548. Thanks, Adam Zajac <<mpc8548cds_i2c2.patch.gz>>

[U-Boot-Users] malloc with no return check?
by Andrew Dyer 13 Mar '06

13 Mar '06

I noticed the au1xxx ethernet driver has a malloc where the return value isn't checked. I did some more looking while waiting for a slow flash programmer and at least these files seem to do the same thing: ./drivers/ns8382x.c ./drivers/bcm570x.c ./drivers/rtl8139.c ./drivers/eepro100.c ./drivers/dc2114x.c ./drivers/e1000.c ./drivers/sk98lin/skge.c ./drivers/cfb_console.c ./drivers/natsemi.c ./drivers/inca-ip_sw.c ./drivers/rtl8169.c ./drivers/pcnet.c ./cpu/mips/au1x00_eth.c ./cpu/ppc4xx/serial.c ./cpu/ppc4xx/405gp_enet.c ./cpu/ppc4xx/440gx_enet.c ./cpu/i386/serial.c ./cpu/mpc8xx/scc.c ./common/hush.c ./cpu/mpc8xx/spi.c ?maybe ./cpu/mpc8260/spi.c ?maybe ./cpu/mpc85xx/ether_fcc.c ./cpu/mpc8260/ether_fcc.c ./cpu/mpc5xxx/fec.c ./cpu/mpc8220/fec.c ./tools/easylogo/easylogo.c I didn't look under the board directory or check all varieties of alloc :-) I will submit patches for the mips stuff hopefully next week. -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] [PATCH] in tftp client, recover from lost ACKs
by Brenda J. Butler 13 Mar '06

13 Mar '06

CHANGELOG entry: * Patch by John McCarthy and Brenda J. Butler, 8 July 2005 When the tftp client sends an ack but it gets lost, the server will resend the block. The client was now expecting the next block and ignored this block, the server never got an ack, and they got stuck. Now the tftp client will ack the block the second (and subsequent) time(s) allowing the tftp session to proceed. This little fix assumes that the server will resend exactly the same contents (same size from same offset). Here is the patch for you to look at; it is also in an attachment where the tabs and lines are preserved better.

[U-Boot-Users] extra headers in xilinx ml300 board
by Michael Libeskind 12 Mar '06

12 Mar '06

/board/xilinx/xilinx_enet/emac_adapter.c and /board/xilinx/xilinx_iic/iic_adapter.c both have a #include <configs/ml300.h> which I believe prevents users from making other board configs under the /board/xilinx directory based on the ML300 that use the xilinx_enet and xilinx_iic adapaters.

[U-Boot-Users] [PATCH] dhcp vendor fields - support opt bootfile, ignore tftp server
by Murray.Jensen＠csiro.au 12 Mar '06

12 Mar '06

This patch adds support for the dhcp vendor optional bootfile (#67). It also ignores the vendor tftp server name option (#66). Both of these are supplied by the DEC Tru64 Unix dhcp server (called "join"), and in the case of the bootfile, it is the only place the boot file name is supplied. There is a perfectly good, 128 byte, field in the main bootp/dhcp packet where the boot file name could have been stored, but it wasn't used - go figure. Cheers!

[U-Boot-Users] LXT971A PHY debugging on MPC8540 Custom Board
by Shirasat Girish-ags032 12 Mar '06

12 Mar '06

Hi , I have partially ported Uboot on one of our MPC8540 based custom boards. I am currently facing problems in bringing up the 10/100Mbps FEC interface. We are using the LXT971A PHY for the FEC interface. Well the problem is that , the MAC is putting out the data but the PHY is failing to put the data on the line. The PHY is successfully able to auto- negotiate. The MAC putting out data was confirmed by the MAC debug registers and by probing the Tx_EN,clock and TX_D lines. I carried out the MAC loop back test which passed . Then went on for the PHY internal loop back test. Well, when the loop back is enabled the MAC fails to transmit the frame successfully. The thing confusing me is that why the MAC frame transmission is getting affected when i enable the PHY loopback test. Any pointers will be very helpful. Regards, Girish

[U-Boot-Users] [Patch][CVS] Adjust CFG_CMD_ECHO as default ENV setting
by Sam Song 12 Mar '06

12 Mar '06

Hi list, Attached patch makes up a fix on CFG_CMD_ECHO. To avoid breaking exists boards, I adjust "echo" as a default command with aggreement of Wolfgang. For the sake of it's effect on all boards, pls check this one more carefully. About 12 boards related was fixed as well. Fix policy is that if CONFIG_CMD_DFL is used, CFG_CMD_ECHO shouldn't be redefined. Did I fix too much or not enough? Ideas pls... Sorry for the late. I just made my PC get CVS tree:-( CVS hasn't supported proxy. It brings me some troubles more or less. Thanks for all your concern, Sam CHANGELOG: * Patch by Sam Song, 19 June 2005: - Adjust echo as a defalut command.

[U-Boot-Users] byteorder of image_header_t members?
by Steven Scholz 12 Mar '06

12 Mar '06

Hi there, if uint32_t members of image_header_t are stored in network byteorder, then all references of these members should use ntohl(), right? So should we fix this for instance: #~> grep "\->ih_magic" * cmd_autoscript.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_bootm.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { >>> cmd_bootm.c: if (hdr->ih_magic != IH_MAGIC) { <<< cmd_bootm.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_bootm.c: (ntohl(hdr->ih_magic) != IH_MAGIC)) >>> cmd_doc.c: if (hdr->ih_magic == IH_MAGIC) { <<< >>> cmd_fdc.c: if (hdr->ih_magic != IH_MAGIC) { <<< cmd_fpga.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_ide.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_nand.c: if (ntohl(hdr->ih_magic) == IH_MAGIC) { cmd_scsi.c: if (ntohl(hdr->ih_magic) == IH_MAGIC) { cmd_usb.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { -- Steven

[U-Boot-Users] [PATCH] include top config.mk only after CROSS_COMPILE is defined
by Friedrich Lobenstock 12 Mar '06

12 Mar '06

Hi Wolfgang! During compiling I just spotted the fact that gccincdir := $(shell $(CC) -print-file-name=include) in the top config.mk does execute "gcc -print-file-name=include" instead of "m68k-elf-gcc ..." which I would expect as i compile for m68k. I think that this does not make much difference as the includes should mostly be the same, but for the sake of completeness I want to bring the attached patch to your attention.

[U-Boot-Users] [PATCH] revised word alignment fixes for word aligned NS16550 UART
by jean-paul.saman＠philips.com 12 Mar '06

12 Mar '06

The patch is created against current CVS 2005 march 1st and fixes problems for boards that only have word access to the NS16550 UART. OBSOLETES: From: Jean-Paul Saman Date: 23-02-2005 Subject: [PATCH] word alignment fixes for word aligned NS16550 UART peripheral CHANGELOG: * Patch by Jean-Paul Saman, 23 Feb 2005 - include/ns16550.h Fixes alignement bug with UART that only supports word aligned access: removed "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" GCC generates bytes access when it encounters the packed attribute regardless if the struct is already word aligned for a platform. Peripherals that can only handle word aligned access won't work properly when accessed with byte access. The struct NS16550 is already word aligned for REG_SIZE = 4, so there is no need to packed the struct in that case.

[U-Boot-Users] Suspect behaiviour if gatewayip not set
by Robin Gilks 12 Mar '06

12 Mar '06

Greetings Having played with netconsole a bit, I've observed that the current behaiviour of warning if gatewayip is not set and then using its value of zero when talking to outside the current subnet is somewhat suspect. The particular case of netconsole means that no error message is evident - it is trying to be sent the error down the ethernet connection that is being initiated with an arp(0.0.0.0)! I propose that the warning message stay but the target address is put into the arp so that a proxying router can reply to it rather then send out a nonsense arp request.

[U-Boot-Users] maybe just one more bug left in building the examples directory in 1.1.2
by John Davis 08 Mar '06

08 Mar '06

Hello I am getting closer to getting the examples code to build. I have added a bunch of object files and library files to the link command in the examples Makefile. However, I have gotten to the last bug and I don't know how to solve it. Below, it complains about __got2_entries. I found this defined in our board directories linker script. The current command line and results: make[1]: Entering directory `/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2 /examples' ppc-linux-ld -g -Ttext 0x40000 \ -o hello_world -e hello_world hello_world.o libstubs.a \ /home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/cpu/ppc4xx/start.o \ /home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/board/fsp1/fsp1_pra.o \ /home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/board/fsp1/eddr2.o \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/common -lcommon \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/lib_generic -lgeneric \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/net -lnet \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/rtc -lrtc \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/board/fsp1 -lfsp1 \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/cpu/ppc4xx -lppc4xx \ -L/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2/lib_ppc -lppc \ -L/opt/fld_fakeroot/opt/mcp/ppc/bin/../lib/gcc-lib/ppc-linux/3.3.3 -lgcc /home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2 /cpu/ppc4xx/start.o(.text+0x25ae):/home/davis/cvs/mcp4/uboot/mine/u- boot-1.1.2/cpu/ppc4xx/start.S:1374: undefined reference to `__got2_entries' ppc-linux-ld: BFD 2.15.90.0.1.1 20040303 (SuSE Linux) assertion fail ../../bfd/elf32-ppc.c:5645 make[1]: *** [hello_world] Segmentation fault make[1]: *** Deleting file `hello_world' make[1]: Leaving directory `/home/davis/cvs/mcp4/uboot/mine/u-boot-1.1.2 /examples' make: *** [examples] Error 2 [davis@dyn-9-152-249-44 u-boot-1.1.2]$ The relevant portion of the linker script which defines the __got2_entries variable. board/fsp1/u-boot.lds: ... stuff snipped __got2_entries = (_FIXUP_TABLE_ - _GOT2_TABLE_) >>2; ... stuff snipped Any advice on how to apply this to my makefile is appreciated.

[U-Boot-Users] [PATCH] CFI support for Versatile & Integrator/CP boards
by Peter Pearse 28 Feb '06

28 Feb '06

The attached gzipped patch was made against the U-Boot GIT head of Oct 31 2005. It is my patch number 012. The patch is independent of patches 009 & 010, but dependent on patch 011. The patch updates the versatile and integrator/CP boards code to use CFI flash, rather than having a hardware dependent flash.c. CHANGELOG: Versatile & Integrator/CP to use CFI flash..

[U-Boot-Users] Patch for drivers/cfi_flash.c; properly detect write errors.
by Marcus Hall 28 Feb '06

28 Feb '06

Hello.. It seems that there is a minor problem in cfi_flash.c that prevents it from detecting that a flash write error has occurred. The first change in the attached patch is trivial, it just makes the strings output for a protected and a non-protected sector have the same length so the output looks prettier.. The second change is in flash_full_status_check(). We have just called flash_status_check() and then did a switch() on the vendor. For intel, we *should* check if there are any error bits if the previous call returned ERR_OK (Otherwise we will have output an error message in flash_status_check() already.) The original code would only check for error bits if flash_status_check() returns ERR_TIMEOUT. -- Marcus Hall marcushall(a)lucent.com *** ../u-boot-1.1.3/drivers/cfi_flash.c Sat Aug 13 17:53:35 2005 --- u-boot-1.1.3/drivers/cfi_flash.c Tue Aug 23 14:47:06 2005 *************** *** 502,508 **** if ((i % 5) == 0) printf ("\n "); printf (" %08lX%s", ! info->start[i], info->protect[i] ?

[U-Boot-Users] [PATCH] cfi_flash.c patches
by Sangmoon Kim 28 Feb '06

28 Feb '06

Hi, The two patches attached are for drivers/cfi_flash.c. cfi_flash-protect.patch adds CFG_FLASH_PROTECT_CLEAR because for some flash memories(such as 28F320C3) all banks are protected after reset. cfi_flash-buffer.patch makes write_buff not to call flash_write_cfibuffer if buffer_size is1. Because for flash memories with buffer_size 1, buffer write is not supported. Regards, Sangmoon Kim
