[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] [Patch] MPC5xxx PSC baudrate calculation
by Sebastian Schau 25 Sep '05

25 Sep '05

Hi, attached is a patch, that fixes a bug in MPC5200 PSC Baud rate calculation. The Problem was, that proper rounding was not applied to baudrate calculation in serial_setbrg(). The formula from serial_init() should be used.

[U-Boot-Users] PATCH: omap5912osk uses CFI driver, (RO) text output of cfi_flash .c
by Michael Bendzick 25 Sep '05

25 Sep '05

* Patches by Michael Bendzick, 14 Jan 2005: - Configure omap5912osk board to use drivers/cfi_flash.c - Remove hardcoded personalized settings from omap5912osk.h - Fix spacing with (RO) marks in 'flinfo' output in drivers/cfi_flash.c The attached patch converts the omap5912osk board to use the main CFI driver, including for buffered writes, improving write throughput by about 10x. Consequently, the board/omap5912osk/flash.c file is removed with this patch. The drivers/cfi_flash.c file is adjusted slightly to make the columns line up better (see example below).

[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.

[U-Boot-Users] [patch]virtex2 fix for bogus download error messages
by Andrew Dyer 24 Sep '05

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.

[U-Boot-Users] common/cmd_mii.c bug and patch
by Andrew Dyer 24 Sep '05

24 Sep '05

The mii info command (the !CONFIG_TERSE_MII version) has a bug in current cvs. If the phy address is passed to the command the code assigns the variable addr to start, instead of the values of addrlo which is extracted from the command line. At that point in the code addr is always 0. to demonstrate find a board with a phy at a non-zero address, compare the results of 'mii info' and mii info 1' (substitute the phy address on the test board for 1). Also in this file on lines 55 and 418 there are two places where a call to mii_init() is conditionally compiled in, but one condition includes defined(CONFIG_MCF52x2) and the other doesn't. Is this intentional? -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] Patches for ARM IntegratorCP, ARM926EJS, and ARM946ES
by Shawn Jin 12 Aug '05

12 Aug '05

Hi, The patches were developed on an ARM IntegratorCP board with ARM946ES. Since the majority code of ARM946ES cpu was copied from ARM926EJS and there was bug about CFG_HZ found in ARM946ES later, I also fixed this CFG_HZ error on ARM926EJS. The major changes are 1. Mulitple core modules support (u-boot.multicm.patch) Following OMAP boards' methodology, I added mulitple core module configuration. For example, integratorcp_946es_config is for IntegratorCP board with ARM946ES, integratorcp_config is for IntegratorCP board with ARM926EJS by default, integratorap_946es_config is for IntegratorAP board with ARM946ES, and integratorap_config is for IntegratorAP with ARM926EJS. Now only two core modules are supported, ARM946ES and ARM926EJS. 2. ARM946ES support (u-boot.arm946es.patch) 3. ARM926EJS bug fix (u-boot.arm926ejs.patch) Fixed CFG_HZ problem. Set CFG_HZ to 1000. The solution is from AT91RM9200. 4. IntegratorCP bug fixes (u-boot.integratorcp.patch) Added SDRAM size information and FLASH support. Philippe, I don't have an ARM926EJS core module. Would you please test the CFG_HZ fix on your system? Thanks. Regards, -Shawn.

[U-Boot-Users] Eliminate calls of _divsi3 on ARM
by Anders Larsen 12 Aug '05

12 Aug '05

Hi, the enclosed patch agains current top of CVS eliminates two calls of the libgcc helper function _divsi3 and _modsi3. Rationale: Certain commercially available tool-chains provides b0rken libgcc.a (compiled with hardware FP) making these helper functions unusable (U-Boot already provides the unsigned counterparts in lib_arm/libarm.a). Changelog: Eliminate calls of ARM libgcc.a helper functions _divsi3 and _modsi3 Cheers Anders

[U-Boot-Users] [patch]fixes for cmd_fpga.c
by Andrew Dyer 08 Aug '05

08 Aug '05

The attached patch: 1) fixes a bug with the 'fpga loadb' command The bug is in calculating the config data size - 4 bytes of length info were being read as signed chars, casted to long, shifted and added. The cast to long was doing sign extension and causing an incorrect result if a byte was greater than 0x80. For me this caused the fpga load to end early and time out waiting for the hardware completion. 2) removes compilation warnings about using __FUNCTION__ concatenated with strings 3) changes the fpga loadb to always print the file header info during a load. I realize this patch is a mishmash - hopefully it's helpful to someone. -- Hardware, n.: The parts of a computer system that can be kicked.
