First, this may work fior you, but it will not work for me. It does not work on PowerPC, and it does not work on MIPS for example. And it does not work if you have configured your BDI200 as recommended, i. e. that it works with a mostly virgin CPU. > Of course this assumes, that your BDI configuration file has setup > memory controller correctly and you can access the RAM. > > Any comments? Yes, This is one of the many things you can do if you know what you are doing. If you don't have a clue it will just cause more problems and questions.

[U-Boot-Users] U-Boot for CSB226
by Omkar Pandit 17 Nov '04

17 Nov '04

Hi, I have CSB226 board having Intel Xscale PXA250 processor on it. The board already has got micromonitor on it. I want to put U-Boot-1.1.1 in it. I have a few queries. 1. I want to put U-Boot-1.1.1 on CSB226 board in RAM and use it as a boot loader for Linux. I do not want to erase the original micromonitor code in Flash, so I need to put the U-Boot in RAM using TFTP of micromonitor. What changes should I make to the configration file of CSB226 to make this possible. 2. Where in RAM should I load the U-Boot. I have already got initrd.bin that has to be loaded in 0xa0800000and zImage that has to be loaded in 0xa0108000. 3. What will be steps to build the U-Boot image, in order to achieve the above setup.

[U-Boot-Users] UART Initialization Problem (ns16550 on arm920t)
by Rodel Miguel 17 Nov '04

17 Nov '04

Hi, I am porting u-boot 1.1.1 on a new board. The board is arm920t based and it's UART port is compatible with ns16550.c so I changed the serial driver (serial.c) on the cpu/arm920t directory with the serial driver + ns16650 module available in the drivers directory. I am using bdi2k for debugging and I have initialized the UART port on the bdi2k config. The problem is that when the initialization routine in armboot_start calls serial_init of the ns16550, there are no messages, i.e. no prompt, on my serial console. When I remove the serial_init on the list of initialization functions of armboot_start, a prompt appears. I can successfully type help, and do other stuff. Whenever I try to remove the initialization routine on my BDI2k configuration and put back the serial_init function on the initialization list, I am not getting any messages on my serial console. What could be the cause of this problem? The initialization routine on the bdi2k and serial_init are almost the same (i tried to make the sequence and the values exactly the same but I get the same result) but there are no messages displayed on my console. =( Thank you very much for your help. Best Regards, Rodel Miguel

Hi All, I have the following queries:- 1. Can anyone tell me how to compile UBOOT using Metrowerks CodeWarrior? 2. I have already complied UBOOT using ELDK. Can anyone tell me how to make CodeWarrior project after compiling UBOOT using ELDK?

[U-Boot-Users] make <board>_config question
by Robin Getz 17 Nov '04

17 Nov '04

All: I was adding a cpu/board to U-boot, and had a quick question: Is there anyway for the process of: ---------------- path> make <board_name>_config Configuring for <board_name> board ... path> ---------------- Can dump any more information out? For example - in my processor, I can set a PLL, and have separate CPU and peripheral clocks. Any thoughts? ---------------- path> make <board_name>_config Configuring for <board_name> board ... Setting CCLK to 500MHz Setting SLCK to 133MHz path> ---------------- Thanks -Robin

[U-Boot-Users] U-boot starts and stops before a command prompt
by Nishant Galange 16 Nov '04

16 Nov '04

Hello The Reference Hardware/Software config: EP8260 M 1.3, 32Mb SDRAM, 8 Mb Flash Reset exception vector at FFF0 0100 WireTAP JTAG connected to my computer's parallel port Serial Terminal and HyperTerminal used for monitor/console. Baud rate: 115200 u-boot 1.1.1 ELDK "Flash Programmer" in CodeWarrior on Windows used for burning u-boot.srec into the FLASH. debug build of u-boot HRCW = 0x10400245 The Problem: On power-up, u-boot starts executing, displays a few messages, and stops. No command prompt. The last message printed is: "New Stack Pointer is: 0x1F3 6F48" In the source code, that message appears just before the call to relocate_code(). relocate_code is implemented in assembly (in cpu/mpc8260/start.S). Since I could not figure out how to debug/single-step through the code using WireTAP, I used printfs and debug()s for debugging. And since printfs are not possible in start.S, I used the on-board LEDs to figure out that the code halts _at_ the branch to in_ram That is where I am stuck. Where does the execution control branch to? How do I figure out where the code is going? I know it does not reach in_ram because the first statements there is my code to glow the LEDs. How do I debug u-boot? Should I use CodeWarrior or gdb? I have never used either of them before. If I have to use CodeWarrior, how do I go about it? Do I have to import the u-boot source tree into the CodeWarrior IDE? Do I have to compile u-boot using CW? If yes, then that's another problem altogether. If I have to use gdb, what commands do I give? I have tried both 'gdb' and 'ppc_82xx-gdb'. (gdb) target remote /dev/lp0 gives errors saying set_tty_state failed: Invalid argument (gdb) target jtag /dev/lp0 and (gdb) target jtag jtag://localhost:9999 give errors saying Undefined target command: "jtag /dev/lp0". Try "help target". Observations / attempts: u-boot 1.1.1 was meant for EP8260 rev. 1.1 (64Mb RAM, 16 Mb Flash) I made the changes necessary for rev. 1.3 in board/ep8260/ep8260.h and include/configs/ep8260.h Kept Flash as 16 Mb (If I change it to 8, no messages appear on the screen) Changed the 60x RAM size to 32 Mb Local bus SDRAM was already 0, no change required. Debug build gives messages: Top of usable RAM found at 0x0200 0000 And other values till it prints: New Stack Pointer at: 01F3 6F48 Any help, pointers, reference, tutorials, etc. would be a great help. I need some help desperately. Warm regards, Nishant

You will have to swap CS0 <-> CS6 configuration information everywhere (especially BR0/OR0 and BR6/OR6 initialization). You will have to change the HRCW definition in the include/configs/sbc8260.h file (the width of the on-board flash is 2 bytes wide vs. 4 bytes, I haven't reviewed anything else in the HRCW) After you get all the software switched, switch the CS0/CS6 hardware jumpers.

[U-Boot-Users] env_init hangs!!!
by Rodel Miguel 16 Nov '04

16 Nov '04

Hi All, I've searched the archives for this, but I'm not successful. I am porting u-boot_1.1.1 on an arm920t based board. I used SMDK2410 as my template for porting. I modified the flash, UART, and memsetup that would suit my board, however there were no messages displayed on the UART. I tried to trace which point in the u-boot code does my system hang. The program counter stops in the crc32 call in the env_init function ( ! CFG_ENV_ADDR_REDUND ). What could be causing my system to hang on the ff. line: if (crc32(0, env_ptr->data, ENV_SIZE) == env_ptr->crc) Thank you very much for your time. Best Regards, Rodel
