[U-Boot-Users] [PATCH] fix building of tools/env programs
by Murray.Jensen＠csiro.au 23 Mar '06

23 Mar '06

This patch shows what I had to do to get the programs in the tools/env directory to build (i.e. fw_printenv/fw_setenv). Your mileage may vary. Cheers! Murray...

[U-Boot-Users] Re: compile u-boot with recent toolchain : symbols problem

I've got the same problem with binutils 2.16 and gcc 3.4.4. also binutils 2.16.91.0.1 doesn't work right. > > > > I used to compile U-Boot with ELDK, but I currently need to work with > > newer toolchain : > > - binutils-2.16 > > - gcc-3.4.3 > > This looks line a binutils problem, then.

The above, i couldn't acknowledge, but u-boot definitly hangs _after_ relocating to memory. it will dump 'Now running in RAM at .....'. But then it hangs. After relocating, it tries to manually relocate the command table. But that doesn't work. Don't know why, but with the patch it works. Obviously __u_boot_cmd_start = .; .u_boot_cmd : { *(.u_boot_cmd) } __u_boot_cmd_end = .; and __u_boot_cmd_start = ADDR(.u_boot_cmd); .u_boot_cmd : { *(.u_boot_cmd) } __u_boot_cmd_end = .; should be the same. However, this should be a binutils bug or the linker script voodoo that is done with the first script above isn't really valid. Maybe .u_boot_cmd gets misalligned. Maybe i should try to DEBUG(& __u_boot_cmd_start) in both (the patched and unpatched) versions to see, where it points, or maybe objdump show more. Btw. this happens on the tqm8xx board. Thanks to Vincent for recovering that, that saved me a lot of time... kind regards Anton Wöllert

[U-Boot-Users] [PATCH] Support for the Lite5200B
by Txema Lopez 17 Mar '06

17 Mar '06

Hi all, This is a patch to support the new Lite5200B board based on the MPC5200B. It has been implemented as a modification of the actual icecube. The main differences beetwen both boards are the type and amount of ram and flash memory. The Lite5200B has 256M of DDR ram and 32 M of flash mapped in two banks.It's used the cfi flash driver but it's needed a patch for this driver to support the x8/x16 flash in x8 mode. There is a patch supplied by Alex Bastos and I supply another one.

[U-Boot-Users] Bug in DTT for temperatures below zero degress !!!

Hi there, there's a terrible bug in the current U-Boot CVS concerning DDT: For temperature below zero the function dtt_get_temp() (at least for lm75) returns wrong values! ... DTT: 1 is 235 C LCD: Hitachi TX14D11 5,7" 320x240 TFT (235°C) WDT: disabled This is because of the use of an "int" although the lm75 only returns two byte ("signed short").

[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>>

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] [PATCH] fix [id]cache_status for MPC85xx processors
by Murray.Jensen＠csiro.au 13 Mar '06

13 Mar '06

The existing code for the [id]cache_status commands on MPC85xx processors looks at the wrong bit to determine if the L1 cache is enabled. It looks at the most significant bit when it should look at the least significant bit. This patch corrects this bug. Cheers! Murray...

[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. Can this be removed?

It is intended to deal with the case if we are configuring a PCI bridge via the pci_config_table, we need some way of reporting back the fact that the bus number has changed. - kumar --- a/drivers/pci.c +++ b/drivers/pci.c @@ -459,6 +459,7 @@ int pci_hose_scan_bus(struct pci_control PCI_BUS(dev), PCI_DEV(dev), PCI_FUNC(dev)); if (cfg) { cfg->config_device(hose, dev, cfg); + sub_bus = max(sub_bus, hose->current_busno); #ifdef CONFIG_PCI_PNP } else { int n = pciauto_config_device(hose, dev);
