bootstrap code is not running
 

Hi,
I am working in Board Bring up project on GESBC-9x25

I have made SDCard into 2 partitions(boot & rootfs).
I have created bootstrap binary for sdcard support(BOOT.BIN)
I have created u-boot.bin & uImage

BOOT.BIN, u-boot.bin & uImage kept in my boot partition of SDCard.
rootfs kept in rootfs partition of SDCard.

inserted my SDCard into board SDCard slot.

when i power on the board, only ROM code is executing...
It is not taking my images at all...

How to tell the processor, have look an SDcard for my remaining images like that.

here on my board, i didn't find boot pins.to change order of boot sequence.

i want to boot up the board with linux...
how to do this...
can any one help me plz.....

See the LQ Rules about text speak and NOT using it..it's "please" not "plz".

And did you try reading the user manual?? Seeing their website?? It has a COMPLETE description, downloadable images, and how-to guides.

bootstrap code is not running
 

Hi,

I have gone through all the above mentioned links...

Actually, the board will come with pre-installed linux on to board Nand flash... while shipping itself.

My requirement is to boot from SDCard,so what i have did is, i erased all the Nand contents by typing in u-boot prompt.
u-boot# nand erase clean
with that above command, pre-installed bootstrap, u-boot,uImage and rootfs are cleaned and gone...

i have prepared all images again and put into my SDcard boot partition

I inserted SDCard onto board SD slot.

when i power on the board now, only ROM code is executing...and cursor stopped...

If i want to change boot sequence,what is the procedure??? and here there is no boot pins on board.

can anyone help me please, how to boot linux on this GESBC-9x25 board.

Thanks very much.

Only limited change is possible to the boot order on the SAM9X25.
But it doesn't matter because the first boot device is SPI flash (which doesn't exist on that Glomation board), and the second device is the MMC/SDcard. The NAND flash is the third boot device, so the SDcard has precedence over the NAND flash.
So that means that you didn't have to erase the NAND flash.

More details please.
How did you format the boot partition?


More details please.
What source file did you use?
What version?
What configuration did you use?

More details please.
What version?

I probably still have a SDcard image for a SAM9G25 project I did a few years ago. I don't recall any difficulties in building it.

Hi,

I have made only 2 partitions of SDCard by using script in this link...
http://processors.wiki.ti.com/index....tition_SD_Card

How BOOT STRAP(BOOT.BIN) is built
------------------------------------------------------------------------------------------------------------------------
1.I cloned the source code from this site.
git clone git://github.com/linux4sam/at91bootstrap.git

2.selected and make default configurations for this board.
venkatesh@venkatesh:~/at91bootstrap$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- at91sam9x5eksd_uboot_defconfig

3.compiled and created Boot strap binary
venkatesh@venkatesh:~/at91bootstrap$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

After this step the binary will be present in "at91bootstrap/binaries" directory
You will see "at91sam9x5ek-sdcardboot-uboot-3.8.4.bin" file which is our Boot Strap file...
changed it's name to BOOT.BIN
and kept in boot partition of SDCard.

How U-boot is built
---------------------------------------------------------------------------------------------------------------------
1. downloaded u-boot-2015.04 source code from denx site.

2. u-boot configuraton
venkatesh@venkatesh:~/u-boot-2015.04$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- at91sam9x5ek_mmc_defconfig

3.u-boot compilation:
venkatesh@venkatesh:~/u-boot-2015.04$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

then we will find "u-boot.bin" in parent directory of source.
that copied to boot partition of SDCard..

If i did mistake please correct me...

and please help me How to boot linux on GESBC-9x25 board.

Thank you very much...

Foul at the starting line!
Those are directions for TI Sitara SoCs.
You're using an Atmel SAM9 SoC.
They may have different requirements.
Instead you should be following SD card boot for AT91SAM SoC

When you built U-Boot or the Linux kernel, did you clone the github, or do you just download a release tarball?
If all you want is source to build, then the better alternative is to use a release tarball: https://github.com/linux4sam/at91bootstrap/releases

FWIW, because of past gcc version issues when building U-Boot, I prefer to use a bare-metal toolchain for compiling AT91Bootstrap and U-Boot.


But before you worry about the toolchain, you need to bisect the problem, and try to determine if AT91Bootstrap has been loaded and tried to execute.
Why did you erase the NAND flash? Was the board booting from NAND even though the SDcard was inserted?

When you try to boot with the SDcard and only see the "RomBOOT" message (as in your minicom screenshot), type "V#" (your keystrokes will not be echoed). Is there any response?
