[U-Boot-Users] [PATCH] OMAP242x/H4 board updates.
by Woodruff, Richard 25 Sep '05

25 Sep '05

Hello, This patch is against a CVS pull from today (3Mar05). It updates the H4 board for operation with the OMAP242x ES2 chip. Along with some other fixes it also switches to using the CFI flash driver for a 6x write speed up. The CFI driver needed some minor changes as this Intel part works on a per partition basis. The current driver would assume that a query command to the base of the part would affect the whole chip. This is not the case. It also had some strange code which acted like sector unlocks were per chip instead of per sector, this is not the case. - OMAP242x H4 board update - fix for ES2 differences. - switch to using the cfi_flash driver. - fix SRAM build address. - fix for GP device operation. - unlock SRAM for GP devices. - display more device information. - fix potential deadlock in omap24xx_i2c driver. - fix DLL load values to match dpllout*1 operation. - fix 2nd chip select init for combo DDR device. - cfi_flash.c - add support for CFI Intel 28F256L18 on H4 board. Regards, Richard W.

[U-Boot-Users] [patch] MIPS: AMD Alchemy au1x00 ethernet initialization in cpu/mips/au1x00_eth.c
by Joseph Chiu 25 Sep '05

Hi, On u-boot bootloader 1.1.2 on AMD Alchemy Au1x00: The au1x00_mac.c assumes that ethernet transmit always starts with transmit buffer 0.

[U-Boot-Users] [PATCH] Use info->reset_cmd instead of FLASH_CMD_RESET
by Zachary Landau 25 Sep '05

25 Sep '05

Hello, This patch makes cfi_flash.c use info->cmd_reset. It was being set by flash_get_size() but not being used, which kept the Flash on my board from properly being reset. It looks like there are a lot of switch cases for different flash types that could probably probably be removed by setting up some function pointers, but that is a project for another time. -- Zachary P.

[U-Boot-Users] [patch] fix lib_generic version of strswab()
by Andrew Dyer 25 Sep '05

25 Sep '05

This patch changes the behavior of strswab() to end the byte swapping when either of the two candidate bytes is null. The old behavior was to only abort when the second byte was null. It looks like this is only used for little endian machines running with CONFIG_IDE. I noticed this because the ide serial number was not printing out - the reason was strswab() was running past the end of the previous string in memory and swapping a null into the first byte of my serial number string. -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] [patch] tools/bmp_logo.c using incorrect offset to pixel data
by Andrew Dyer 25 Sep '05

25 Sep '05

The attached patch makes bmp_logo.c use the header information about the start of pixel data in the bmp file instead of trying to find the start itself. If someone wants a test case bmp file that will produce incorrect output with the current code e-mail me and I can send it along. The bug was seen with the tool compiled/running under redhat 7.3 on x86 arch. The visual indication was that the bitmap was shifted to the right with a section of garbage displayed in the lower left corner. The source bmp displays fine with Win2000. I would suggest it's worth noting in the somewhere in docs that include/bmp_logo.h is overwritten by the default build environment (with the Denx logo :-( ). I added a line like this to my board config.mk file to override this behavior. #logo bitmap LOGO_BMP = ../board/eldorado/rht_small_logo.bmp -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] MIPS build environment
by Dan Malek 25 Sep '05

25 Sep '05

Hello all MIPS u-booters. I'd like to discuss how we can make the MIPS build environment a little bit easier to use. For example, the cpu/mips/config.mk assumes big endian, and although I'll be the first to stand up and say that's the only proper and useful byte ordering, there are people willing to pay me to assist with the alternative :-) I'd like it if we can just find a way to invoke 'mipseb-*' or 'mipsel-*' based upon the configuration chosen and let it go at that. I'd also like us to agree to use up to date tools. Again, the config.mk with the test and hard coded flags depending upon tools seems unnecessary since the newer tools have been around for a while and proven to work. Unless I'm doing something wrong, I also have to use binutils with the 'allow_branch_to_undefined' patch. Comments? Other concerns? Thanks. -- Dan

[U-Boot-Users] Lowering memory footprint
by Ladislav Michl 24 Sep '05

24 Sep '05

Hi Wolfgang et all, I ported U-Boot to OMAP5910 based board and before submiting patch I'd like to discuss few issues. Board has 64M RAM and 32M bit mirror flash, which is quite sufficient to run U-Boot under normal circumstancies. During production of prototypes I met few boards with bad printed circuit board or bad soldering. Therefore I decided to run U-Boot from OMAP's 192kB internal RAM located at 2000'0000-2002'ffff with TEXT_BASE set to 2001'2000. That way I have 64kB heap and 8kB stack, which I found is sufficient for my needs. Such setup helps a lot while debugging hardware problems, despite I know it could be done different way, but it would be pity not to use U-Boot's power :) Because CFG_MALLOC_LEN is 64k-128 something like this is needed to startup code: Index: cpu/arm925t/start.S =================================================================== RCS file: /cvsroot/u-boot/u-boot/cpu/arm925t/start.S,v retrieving revision 1.8 diff -u -r1.8 start.S --- cpu/arm925t/start.S 9 Jan 2005 17:12:29 -0000 1.8 +++ cpu/arm925t/start.S 12 Jan 2005 12:45:27 -0000 @@ -83,6 +83,10 @@ _TEXT_BASE: .word TEXT_BASE +_STACK_OFS: + .word CFG_MALLOC_LEN + CFG_GBL_DATA_SIZE +_BAD_STACK_OFS: + .word CFG_MALLOC_LEN + CFG_GBL_DATA_SIZE + CONFIG_STACKSIZE + 8 .globl _armboot_start _armboot_start: @@ -188,8 +192,8 @@ /* Set up the stack */ stack_setup: ldr r0, _TEXT_BASE /* upper 128 KiB: relocated uboot */ - sub r0, r0, #CFG_MALLOC_LEN /* malloc area */ - sub r0, r0, #CFG_GBL_DATA_SIZE /* bdinfo */ + ldr r1, _STACK_OFS + sub r0, r0, r1 /* malloc area and bdinfo */ #ifdef CONFIG_USE_IRQ sub r0, r0, #(CONFIG_STACKSIZE_IRQ+CONFIG_STACKSIZE_FIQ) #endif @@ -293,8 +297,8 @@ stmia sp, {r0 - r12} @ Save user registers (now in svc mode) r0-r12 ldr r2, _armboot_start - sub r2, r2, #(CONFIG_STACKSIZE+CFG_MALLOC_LEN) - sub r2, r2, #(CFG_GBL_DATA_SIZE+8) @ set base 2 words into abort stack + ldr r13, _BAD_STACK_OFS + sub r2, r2, r13 ldmia r2, {r2 - r3} @ get values for "aborted" pc and cpsr (into parm regs) add r0, sp, #S_FRAME_SIZE @ grab pointer to old stack @@ -326,8 +330,8 @@ .macro get_bad_stack ldr r13, _armboot_start @ setup our mode stack - sub r13, r13, #(CONFIG_STACKSIZE+CFG_MALLOC_LEN) - sub r13, r13, #(CFG_GBL_DATA_SIZE+8) @ reserved a couple spots in abort stack + ldr r2, _BAD_STACK_OFS + sub r13, r13, r2 str lr, [r13] @ save caller lr in position 0 of saved stack mrs lr, spsr @ get the spsr Flash is partitioned this way: 128k - U-Boot 128k - env 16256k - data1 16256k - data2 Kernel is loaded directly from jffs2 partition to ease firmware upgrating.

My question is whenever I should make only CramFS selectable or allow choice between JFFS2 and/or CramFS and how should be such configuration handled (you know it's quite hard for me to come with some nice short descriptive names :)) And finally ~64k heap is not sufficient for zlib to decompress kernel after it is loaded from jffs2 partition, because node structures are still allocated.

24 Sep '05

the virtex2 fpga download code watches for init going active during a download of config data as an error condition. init also goes active after a configuration is finished in concert with the done signal. The code in cvs doesn't check for done active until all of the configuration data is sent. On our board the done signal would go active "early" as the configuration data has a few extra pad bytes at the end, but the code would print an error message even though the download had suceeded. The patch adds a check for done going active before checking init. If done is seen active the byte loading is cut short. If debugging is on it will print the count where it finished (8 bytes early for us). It also changes the printf string to indicate the counts it prints are in ticks and not mS. I only have a system with 'slave parallel' style config interface, so I've only patched that download version. The virtex2 slave serial and spartan2 versions may have the same problem, I didn't have time to look. -- Hardware, n.: The parts of a computer system that can be kicked.

Hi Wolfgang, try three on the patch attached. The change here is to rename the env variable per Tolunay Orkun's recommendation. * Patch by Jerry Van Baren 11 January 2005 - Add a configuration option CONFIG_TFTP_PORT and optional env variable tftpsourceport to force TFTP to use a fixed UDP port. gvb Index: README =================================================================== RCS file: /cvsroot/u-boot/u-boot/README,v retrieving revision 1.117 diff -p -u -r1.117 README --- README 9 Jan 2005 23:16:42 -0000 1.117 +++ README 10 Jan 2005 04:13:50 -0000 @@ -1480,6 +1480,22 @@ The following options need to be configu When SystemACE support is added, the "ace" device type becomes available to the fat commands, i.e. fatls. +- TFTP Fixed UDP Port: + CONFIG_TFTP_PORT + + If this is defined, the environment variable tftpsourceport + is used to supply the TFTP UDP source port value. + If tftpsourceport isn't defined, the normal pseudo-random port + number generator is used. + + The purpose for this is to allow a TFTP server to + blindly start the TFTP transfer using the pre-configured + target IP address and UDP port.

[U-Boot-Users] dbau1550 patch
by Andrew Dyer 24 Sep '05

24 Sep '05

A while back (Sep 23, 2004) someone named Leif posted a note about a patch to add support for the AMD DbAU1550 board to u-boot here https://sourceforge.net/mailarchive/forum.php?thread_id=5624545&forum_id=12… I can't seem to find the patch he referred to and I would like to get a hold of it. -- Hardware, n.: The parts of a computer system that can be kicked.
