[U-Boot-Users] FLASH AM29LV320DB on AdderII
by Raghu 05 Aug '03

05 Aug '03

hello all, On the AdderII, I am facing some issue w.r.t Flash. I am able to erase sectors but not correctly able to program. The reason I understand so far is because I am trying to write ulong data, while it is writing only a word. Code sample **************************************************** static int write_word (flash_info_t *info, ulong dest, ulong data) { vu_short *addr = (vu_short *)(info->start[0]); ulong start; int flag; /* Check if Flash is (sufficiently) erased */ if ((*((vu_long *)dest) & data ) != data ) { return (2); } /* Disable interrupts */ flag = disable_interrupts(); addr[0x0555] = 0xAAAA; addr[0x02AA] = 0x5555; addr[0x0555] = 0xA0A0; *((vu_short *)dest) = data; /* re-enable interrupts if necessary */ if (flag) enable_interrupts(); /* data polling for D7 */ start = get_timer (0); while ((*((vu_short *)dest) & 0x8080) != (data & 0x8080)) { if (get_timer(start) > CFG_FLASH_WRITE_TOUT) { return (1); } } return (0); } ****************************************************** __________________________________ Do you Yahoo!?

[U-Boot-Users] problem compiling sc520
by david stevenson 05 Aug '03

05 Aug '03

I am still having problems with this. I have applied the patches Brad sent on Sat to the CVS of yesterday, by hand. But gcc 3.2 -Werror and " goto done; ...... done: } do not appear compatable, so I changed the easiest option and removed -Werror. I now have lib_i386/libi386.a(video_bios.o): In function `probe_pci_video': /home/david/smart/cvs/u-boot/lib_i386/video_bios.c:88: undefined reference to `pci_find_class' Can someone who gets past this let me know where the function is? Thanks David

RE: [U-Boot-Users] serial download via Hyperterm very slow
by Woodruff, Richard 04 Aug '03

- The hyperterm speed will somewhat depend on your image, I seem to get around 3500cps. If I suspend my machine with out a clean startup it gets are 2500 consistently, fifo not reset right?... - Teraterm for windows seems to do a bit better, it doesn't have any status report so you have to make measurements via a watch. - Hyperacces (the pay version of hyperterm) in the past has usually done about 1000cps better than hyperterm for most things. The noteworthy bit about this one is it allows you to set the max packet sizes and delays between xmits, .... Hyperterm doesn't seem to allow parameter tweaking. -- C-Kermit on Linux for me does about 8800 cps, I suspect that its doing better because we set the .kermrc to use 1000 character packets. Hyperaccess (pay version of hyperterm) won't allow setting it about ... 97 characters or something. They likely are compiling in a lot older version of kermit, or working around some old and obsolete windows bug. --- So to make it faster, I'll agree which Wolfgang, get the latest windows compiled C-Kermit (there will be a windows binary about), and teak its packet size up and you will probably see something around 8000cps.

hi , If I try to use hyperterm for serial download with u-boot on my 1510 innovator board, the download rate is very slow (around 2250 cps). I know that u-boot encourages the download via C-Kermit for loadb, But any pointers on how to do it fast on windows will be helpful. regards -kshitij

[U-Boot-Users] New user - 386
by david stevenson 04 Aug '03

04 Aug '03

Hi To introduce myself, and warn you of silly questions to come 8-) I am starting on a project to use Linux on existing sc400 hardware. (the sc400 is an older less powerful but more features sc520). U-boot looks like a very fine project for my needs. I have been reading the readme and some of the code, so until I know more only general questions. First easy question, can someone confirm the sc520 version is complete? ie it does not depend on any other bios or similar code on the board. Second is anyone else using the sc400 (or sc410), or have any information on existing config files? David Stevenson

[U-Boot-Users] how to detect the expanded flashRAM SIMM on ZPC1900 board ?
by Xiong Jiang 04 Aug '03

04 Aug '03

Hi, there, I am playing with a PPC8265 based ZPC1900 board (from zpci.com). There is an expanded 8M FlashRAM SIMM on it. However flinfo in U-Boot 0.3 only shows the Bank # 1 AMD AM29F016D 2M flash memory. Bank # 2 is "missing or unknown FLASH type. However that expanded flash RAM is bootable if I switch the boot selection jumper J14 on the board. The ZPC1900 manual (http://www.zpci.com/Product_Documents/ZPC_1900/ZPCI_1900_manual_prelim_12.P…) shows that 8MB SIMM Flash is addressable at 0xE0000000. However a 'md.b e0000000 16' command in U-boot cause bus error and reboot. Does anybody know how to access the 8MB SIMM flash ? Actually what I need to do is to copy the on-board boot flash into that 8M SIMM flash as a backup. Any advice is appreciated. Regards, Xiong Jiang

[U-Boot-Users] Function pointers after relocation
by Robin Gilks 03 Aug '03

03 Aug '03

Greetings When u-boot has relocated from Flash to RAM, it is correct that function pointers (eg. getenv()) still point to the Flash code rather than the RAM copy? Would this be corrected by changing the link address, in which case where do I find it (the link address that is) - in the .lds file? board = mpc866ads (fads alike) cpu = mpc866 (mpc860 alike) all changes based on ads860+fads merge!! -- Robin Gilks Senior Design Engineer Phone: (+64)(3) 357 1569 Tait Electronics Fax : (+64)(3) 359 4632 PO Box 1645 Christchurch Email : robin.gilks(a)tait.co.nz New Zealand

[U-Boot-Users] u-boot for SC520 - patches for cvs
by Brad Parker 02 Aug '03

Hi, I'm attempting to build u-boot for the SC520, starting with the AMD eval board. The code in cvs doesn't build. With the patch below it builds. But, the "objdump" to srec fails... If I do the objdump to a binary file I get a 900mb file :-) obviously objdump is attempting to fill some gap - but how to fix this? something tells me this behavior is "new" and didn't happen with older objdumps... also, in case it's interesting I've been able to do a lot of debugging with bochs, using a modified link directive file... -brad Index: Makefile =================================================================== RCS file: /cvsroot/u-boot/u-boot/board/sc520_cdp/Makefile,v retrieving revision 1.2 diff -u -r1.2 Makefile --- Makefile 27 Jun 2003 21:32:24 -0000 1.2 +++ Makefile 2 Aug 2003 15:07:27 -0000 @@ -29,7 +29,7 @@ SOBJS := sc520_cdp_asm.o sc520_cdp_asm16.o $(LIB): $(OBJS) $(SOBJS) - $(AR) crv $@ $(OBJS) + $(AR) crv $@ $(OBJS) $(SOBJS) clean: rm -f $(SOBJS) $(OBJS) Index: sc520_cdp.c =================================================================== RCS file: /cvsroot/u-boot/u-boot/board/sc520_cdp/sc520_cdp.c,v retrieving revision 1.6 diff -u -r1.6 sc520_cdp.c --- sc520_cdp.c 27 Jun 2003 21:32:24 -0000 1.6 +++ sc520_cdp.c 2 Aug 2003 15:07:27 -0000 @@ -28,7 +28,7 @@ #include <asm/pci.h> #include <asm/ic/sc520.h> #include <asm/ic/ali512x.h> -#include <ssi.h> +#include <spi.h> #undef SC520_CDP_DEBUG @@ -557,6 +557,20 @@ } } +void spi_eeprom_probe(int x) +{ +} + +int spi_eeprom_read(int x, int offset, char *buffer, int len) +{ + return 0; +} + +int spi_eeprom_write(int x, int offset, char *buffer, int len) +{ + return 0; +} + void spi_init_f(void) { @@ -585,6 +599,9 @@ #endif #ifdef CONFIG_SC520_CDP_USE_MW res = mw_eeprom_read(2, offset, buffer, len); +#endif +#if !defined(CONFIG_SC520_CDP_USE_SPI) && !defined(CONFIG_SC520_CDP_USE_MW) + res = 0; #endif return res; } @@ -606,6 +623,9 @@ #endif #ifdef CONFIG_SC520_CDP_USE_MW res = mw_eeprom_write(2, offset, buffer, len); +#endif +#if !defined(CONFIG_SC520_CDP_USE_SPI) && !defined(CONFIG_SC520_CDP_USE_MW) + res = 0; #endif return res; } Index: u-boot.lds =================================================================== RCS file: /cvsroot/u-boot/u-boot/board/sc520_cdp/u-boot.lds,v retrieving revision 1.3 diff -u -r1.3 u-boot.lds --- u-boot.lds 27 Jun 2003 21:32:24 -0000 1.3 +++ u-boot.lds 2 Aug 2003 15:07:27 -0000 @@ -31,7 +31,7 @@ .text : { *(.text); } . = ALIGN(4); - .rodata : { *(.rodata) } + .rodata : { *(.rodata) *(.rodata.str1.1) *(.rodata.str1.32) } . = 0x400000; /* Ram data segment to use */ _i386boot_romdata_dest = ABSOLUTE(.);

[U-Boot-Users] Hi,
by Divyesh Patel 01 Aug '03

01 Aug '03

Hi, I am new to Linux and U-Boot. I am using the MPC8266 BSP for MPC8266ADS reference board from Metrowerks as my base point to start my project specific board BSP. I am wondering if someone can help with telling me what sets of files I would have to modify in U-Boot to input my board specific details so that the U-Boot will work on my board. Also any other pointers would be really appcreciated. Regards, Divyesh Patel

What is the value of TEXT_BASE in your > "board/ep8260/config.mk" file? I'm sure, TEXT_BASE = 0xFF000000, I'm actually trying to determine why the code works so well (!!). I am intentionally switching the FLASH from a low address configuration to a high address configuration by overwriting BR0. Looking at the code I was expecting it to fall over when I did this ?? M.

[U-Boot-Users] Difficulty with symbol maps.
by Mark Doherty 01 Aug '03

01 Aug '03

Hello, I am experiencing some difficulty loading my symbol table into gdb, I'm not sure whether it is a common fault with gdb or perhaps finger trouble on my part. I have built u-boot for an ep8260 & my custom target such that the code lives in flash memory at 0xFF000000. However the reset configuration word is programmed to initialise flash at address 0x00000000. This appears to work ok as the board does indeed boot correctly. However I would like to be able to step through the code using a BDI2000. When I attempt to load the symbol file into gdb at address 0x00000000, the symbol _start which I expected to reside at 0x100 actually resides at address 0xFE000100 as illustrated in the following trace. $ ppc-linux-gdb GNU gdb 5.1.1 Copyright 2002 Free Software Foundation, Inc.

(gdb) info address _start Symbol "_start" is at 0xfe000100 in a file compiled without debugging. (gdb) Interestingly, when I attempt to load the symbol map at any other address than zero the symbols appear fine. Any ideas or thoughts would be appreciated. Many thanks Mark Doherty.
