Hi Hannes,
So I did as you had indicated and made some progress, so now, my
#defines
look as below. #define CONFIG_SYS_MMC_ENV_DEV 0 /* device 0 */ #define CONFIG_ENV_OFFSET 0x21900000
I calculated the env offset from the block number it was on based on
the
first block number of the partition.
Doing this on uboot startup, I dont get the warning saying, using
default
environment. Neither it complained abt crc error. So it liked it
seems.
But what it did is it trashed the partition which had my dtb and
zImage.
Its a completely different partition. So after that, the bootup gets halted. Any ideas ? What may have trashed the partition ?
Look at: http://www.mail-archive.com/u-boot@lists.denx.de/msg146396.html
and see if that's relevant, specifically the second patch which restores
the mmc device offset calculations to the values that correspond to the partition number that's represented in the device structure.

Hi Peter, i don't think that your patch has influence on this issue, due to no partition switching is done anymore.
Further i would like to check your patch series, i am not sure if there is everything ok. I will do so tommorow - i am right in thinking that you are using MMC not eMMC ?
best regards, Hannes
