[U-Boot] Not able to change the UBoot env variables from Linux

[U-Boot] Creating partitions on NAND flash
Hi All, I would like to partition the NAND flash on a canyonlands board. As per my understanding, the partitioning is done using the add_mtd_partitions function in the file drivers/mtd/mtdpart.c. I also understand that the information about a partition is stored in the structure : struct mtd_partition . I could not find out where this structure is getting populated in the u-boot code. Could somebody point out the file in which these partitions are created? I am also interested in knowing the file in which the different start / end addresses for these partitions are defined.

I recently had a similar problem - the solution was a combination of DTS

#define CFG_CONSOLE_IS_IN_ENV /* Otherwise it catches logbuffer as output */
With the image I built after this changes, I tried to execute the diag
command on the u-boot prompt. It shows only the rtc test.
What else should I add to get other tests under the diag command ?

[U-Boot] U-Boot Hanging
Hi, I have compiled u-boot (for nand flash, using canyonlands_nand_config) for the canyonlands board having a PPC460Ex. I have flashed the u-boot-nand.bin to the NAND flash. When I boot from the NAND flash the u-boot starts giving outputs onto minicom, but it hangs after just a few statements. U-Boot 1.3.4-00380-g302e52e (Sep 8 2008 - 15:37:41) CPU: AMCC PowerPC 460EX Rev. A at 600 MHz (PLB=200, OPB=100, EBC=100 MHz) Security/Kasumi support Bootstrap Option H - Boot ROM Location I2C (Addr 0x52) Internal PCI arbiter disabled 32 kB I-Cache 32 kB D-Cache Board: Canyonlands - AMCC PPC460EX Evaluation Board, 2*PCIe, Rev. 16 I2C: ready DTT: 1 is 47 C DRAM: 512 MB Has anybody faced this issue?

[U-Boot] How to do a basic memory test test using BDI??
Hi, Can I write simple tests for the RAM on a PPC460 and execute it using the BDI debugger? If I don't have linux / u-boot up on my board, how can I test the RAM?

[U-Boot] Enabling POST for canyonlands board
Hi, Is the Power On Self Test enabled for the canyonlands board? What I want to know is whether I need to set any macro while compiling, to enable POST. I saw that there are some hot keys defined to start POST for certain boards. Is there anything defined like that for canyonlands board.How do I start the POST. Thanks in advance.

Re: [U-Boot] Enabling POST for canyonlands board
Hi Stefan, Thanks for the reply. I looked into the file that you mentioned and also the README as well as the POST directory. I could not go into the details very minutely. From this I have understood that 1. Support for POST for canyonlands board is present. 2. To enable POST for canyonlands board, I only have to define the required macros. 3. I do not have to add / modify code to test the peripherals on the canyonlands board. Could you please let me know if I have understood it correctly? Thanks a lot. I am hard pressed for time and your suggestions are invaluable.

A quick look at the canyonlands config header shows that it's not enabled. What I want to know is whether I need to set any macro while compiling, to enable POST. Yes. I suggest you take a look at the kilauea.h header. Here POST is enabled by default. I saw that there are some hot keys defined to start POST for certain boards. Is there anything defined like that for canyonlands board.How do I start the POST. Some POST tests are run always after poweron, and some (longer) tests are only run under certain conditions. doc/README.POST should give you an overview here.

Re: [U-Boot] Flashing u-boot on NAND flash
Hi, I was going through the u-boot archives and I came across a reply from Leonid (http://lists.denx.de/pipermail/u-boot/2008-March/030788.html) Accordingly I did the following : 1. I set the TEXT_BASE to the address 0x100 in board/amcc/canyonlands/config.mk 2. The initdram function in board/amcc/canyonlands/canyonlands.c was left alone as it contained only the following code : return CFG_MBYTES_SDRAM 20; 3.i did not have the file board/xilinx/ml403/u-boot.lds, instead of that, I used the file board/xilinx/ppc440generic/u-boot-ram.lds. With these changes I compiled the u-boot and it compiled properly. Then I loaded the bin file using the BDI 3000 to the location 0x100, I set rm pc 0x1000100 And entered the command go. After this I expected to get the u-boot messages through the serial port on minicom. But I din get anything on minicom. Could you please guide me as to where I am going wrong?

AFAIK, the BDI doesn't support direct NAND reading/writing. Also from the mailing lists I understand that it is difficult to execute the u-boot by directly downloading to the RAM and executing it. Please guide me on how to approach this. This is indeed not so easy. Currently there is no 4xx U-Boot target option to configure the image to boot directly from already configured SDRAM as until now all 4xx boards were able to boot from NOR FLASH. When only NAND booting is supported as in your case, you probably need such an configuration option such as CONFIG_SKIP_LOWLEVEL_INIT which is available on other platforms (MIPS, ARM).
