[U-Boot-Users] u-boot porting problem
by dune summer 19 Sep '06

19 Sep '06

I'm porting u-boot 1.1.4 to my custom MPC8541 board, The resource on my board is like this: LCS0 Boot flash 0xFFF8_0000-0xFFFF_FFFF 512KB CCSR Default Value 0xFF70_0000-0xFF7F_FFFF 1MB LCS1 NvRAM 0xFF6E_0000-0xFF6F_FFFF 128KB CPLD 0xFF60_0000-0xFF67_FFFF 512KB LCS2 Image Flash1 0xF400_0000-0xF5FF_FFFF 32MB LCS3 Image Flash2 0xF600_0000-0xF7FF_FFFF 32MB CS1 discret DDR Bank1 0x0000_0000-0x07FF_FFFF 128MB CS0 discret DDR Bank0 0x0800_0000-0x0FFF_FFFF 128MB PCI memory space 0x8000_0000-0x9000_0000 512MB Because my board have no SPD_EEPROM for DDR config,so I choose MPC8560ads board as template. First I change the init.S file,rearrange the TLB entry according to my board, then I change include/configs/mpc8560ads.h according to my board, then compile and burn the u-boot.bin into boot flash. After power on,there have nothing dump from console. I have freescale codewarrior and USBTAP by my hand,so I debug the u-boot with CodeWarrior and I found that the program fly away from start.S->inflash:->bl cpu_init_f. Anybody who can help me to resolve this problem? And any suggestion should be appreciated. By the way,is there any other method to debug u-boot before console dump on mpc85xx,such as light led on GPIO pin? I think CodeWarrior is hard to use,could anybody use it successfully can share me some useful experience. I'm not familar with PPC assemble language,anyone can tell me what's the meaning ".long" in this sentence? .long TLB1_MAS0(0, 0, 0) Thanks. dune --------------------------------- All-new Yahoo!

[U-Boot-Users] facing problem in cmd_flash.c
by Subhransu Prusty 19 Sep '06

19 Sep '06

while compiling for my lsi(arm7tdmi based) board i am getting some undefined references in cmd_flash.c like flash_print_info, flash_erase. i have included common.h(which includes flash.h) in the cmd_flash.c and in the flash.c also. in flash.c i have given the definition for flash_print_info and flash_erase. Here in the following i am giving the snippets of the code where i am getting the error. in cmd_flash.c - #include <common.h> .... flash_print_info (&flash_info[bank]); //here at this point i am getting undefined reference error ....... in flash.h - ..... extern void flash_print_info (flash_info_t *); in /board/flash.c - void flash_print_info (flash_info_t *info) { int i; ...... } can anybody please solve this problem -- thanks & regards Subhransu Sekhar Prusty +91-9885212073

[U-Boot-Users] support usb storage in u-boot for at91rm9200

---------- Forwarded message ---------- From: kiennd <kiennd(a)gmail.com> Date: Sep 18, 2006 3:05 PM Subject: support usb storage in u-boot for at91rm9200 To: u-boot-users(a)lists.sourceforge.net Hi everybody! I'm building u-boot bin file to load into ARM9 single board ( Atmel AT91RM9200 ). With default functions ( command ) of u-boot version 1.1.4, u-boot is loaded into my board and run correctly. Note: I use u-boot-1.1.4-g7213859d.tar.bz2<ftp://ftp.denx.de/pub/u-boot/u-boot-1.1.4-g7213859d.tar.bz2>downloaded from ftp://ftp.denx.de/pub/u-boot/, I also try u-boot source from git repository http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git But when i add some functions for usb storage ( i want to boot my debian os in compact flash ), u-boot can't start. some lines added in include/configs/at91rm9200dk.h ############################################################ #define CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_COMMANDS \ ((CONFIG_CMD_DFL | CFG_CMD_MII | CFG_CMD_PING | CFG_CMD_USB ) & \ ~(CFG_CMD_BDI | \ CFG_CMD_IMI | \ CFG_CMD_AUTOSCRIPT | \ CFG_CMD_FPGA | \ CFG_CMD_MISC | \ CFG_CMD_LOADS )) /* For USB support */ #if (CONFIG_COMMANDS & CFG_CMD_USB) #define CONFIG_USB_STORAGE #define CONFIG_USB_OHCI #define CONFIG_DOS_PARTITION /*#define CONFIG_USB_KEYBOARD */ /*#define CFG_DEVICE_DEREGISTER */ /*#define CONFIG_SUPPORT_VFAT*/ #define LITTLEENDIAN #endif /* CONFIG_COMMANDS & CFG_CMD_USB*/ ############################################################ Then build u-boot.bin and load into. The terminal display : ###################################### 1: Upload loader to Dataflash with vector 6 modification. 2: Upload u-boot to Dataflash. 3: Upload linux to Dataflash 4: Start U-boot 5: [nm] Identify Dataflash [nm] dataflash_print_info :.id = DataFlash:AT45DB321 Dataflash read successful: Starting U-boot ###################################### and stop here.... and I can't use u-boot. Can you give me some suggestion. If possible, can you share me your u-boot.bin . PS: I send you some attack files: one for my u-boot.bin ( can't start ), one for at91rm9200dk.h, one for my board picture. You check and give me some suggestion. Thank you!

[U-Boot-Users] Question about ld script for s3c44b0
by gwunangle 18 Sep '06

18 Sep '06

hi guys, I have a doubt about the following code which is from u-boot-dist/board/dave/b2 /*code*/ 0 OUTPUT_FORMAT("elf32-littlearm", "elf32-littlearm", "elf32-littlearm") 1 OUTPUT_ARCH(arm) 2 ENTRY(_start) 3 SECTIONS 4 { 5 . = 0x00000000; 6 7 . = ALIGN(4); 8 .text : 9 { 10 cpu/s3c44b0/start.o (.text) 11 *(.text) 12 } 13 14 . = ALIGN(4); 15 .rodata : { *(.rodata) } 16 17 . = ALIGN(4); 18 .data : { *(.data) } 19 20 . = ALIGN(4); 21 .got : { *(.got) } 22 23 . = .; 24 __u_boot_cmd_start = .; 25 .u_boot_cmd : { *(.u_boot_cmd) } 26 __u_boot_cmd_end = .; 27 28 armboot_end_data = .; 29 30 . = ALIGN(4); 31 __bss_start = .; 32 .bss : { *(.bss) } 33 _end = .; 34 } /*code*/ My question: Let's assume it boots from ROM which starts at 0x0(address) and s3c44b0 has no remap mechanism by the way. After bootloader relocates section .text,.rodata,.data and .got from ROM to RAM, we get two copies of codes and data. So here come the question: ldr pc, _start_armboot _start_armboot: .word start_armboot When the above code is executed, which start_armboot is called, the one is ROM or the one in RAM? I mean how we can assure cpu fetches code from RAM instead of ROM to be more efficient? I think u-boot.lds acts just like a scatter file.(Am I right?) So maybe we can write like this: .=ROM_BASE section: { start.o(.text) lowlevel_init.o(.text) } .=RAM_BASE section: { *(.text) } . = ALIGN(4); .rodata : { *(.rodata) } ...and so on OK,this is my opinion. I need you guys comment on it. If i am wrong, please give me the right answer so i won't doubt any more. Sincelely, i need your help. -- Best Wishes! Sincerely yours gWuNangle -- Never Understand Radical Version
