We are using eMMC instead of NAND flash in our own imx25 custom board. We flashed u-boot , u-image into SD Card. And boot configuration is also changed to boot from SD card. When we try to boot we are getting following error repeatedly. Is there any configuration required in u-boot?

Hi,
I changed statement if(gd->env_valid == 1) in env_common.c file. Now its booting fine..
But now I am having other issues in rootfs I am not able to mount rootfs.
Please check attachment for log
and also when i enter command saveenv in u-boot, its trying to save in NAND. please tell me how to change it to MMC
Thanks
Gokul
i found problem in env_common.c under common directory
here in statement if (gd->env_valid == 0) is failed and trying to call functio env_relocate_spec ()
this function env_relocate_spec() is not been called. i need to know what this if statement and this env_relocate function doing.
Thanks
Gokul
Are you using u-boot binary from Freescale binary release on a custom HW?
You will most probably have to rebuild u-boot to correspond to your HW, as it's probably different from i.MX25PDK .
Might make sense to check in sources what u-boot does if it's configured to read init script from NAND and NAND is not found - resets may be coming from that or the fact you're using u-boot that is not customized for your HW.

Hi Vladan,
u-boot is working fine in our custom board when we use NAND. But when we connect SD card to the board and booting from SD card also working fine. But when we try to bood from SD card without NAND is failed. i am getting above error.
Thanks

HI Jorge,
i tried your image it booting completely. But it failed to saveenv and also if i run run bootcmd_mmc i am getting following error

Hi Gokul,
- You should be compiling mx25_uboot.h instead of mx25_uboot_mfg.h. Is this correct in your system?
- How are you configuring your bootargs? I'm attaching the reference manual with instructions o how to do it in order to boot from SD.
- Did you copy the same legend 3 times? Or is your system resetting?
- Are you able to boot from SD using the MX25 PDK?
Best regards.
Jorge.
Hi Jorge,
Thanks for your reply.. please check below answer for your question
- You should be compiling mx25_uboot.h instead of mx25_uboot_mfg.h. Is this correct in your system?
I dont know about this. please tell me where to check
- How are you configuring your bootargs? I'm attaching the reference manual with instructions o how to do it in order to boot from SD.
I not able to get into command line to put all this environmental variables
- Did you copy the same legend 3 times? Or is your system resetting?
its continuously print this message repeatedly
- Are you able to boot from SD using the MX25 PDK?
Yes.
Thanks
Gokul
