The following issues on SabreSD board with JB4.3_1.0.0 images.

1) Initially there was build error, and I follow the community page (https://community.freescale.com/thread/307477) to resolve and generated the uImage & uboot.bin for Mfg tool.

 

 

2) with the generated uboot & uImage, I am getting following  error. The detail logs is attached.

Hi PKZ,

I saw the same issue on the Linux L3.0.35_4.1.0 source code. I searched and found the root cause is the ENGR00268442 mmc: remove the boot partition access codes on 3.0.35.

linux-2.6-imx.git - Freescale i.MX Linux Tree

What you can do is to modify the ucl2.xml as described in Documentation/mmc/mmc-dev-parts.txt.

I changed the command

echo 1 > /sys/devices/platform/sdhci-esdhc-imx.3/mmc_host/mmc0/mmc0:0001/boot_config

to

echo 0 > /sys/block/mmcblk0boot0/force_ro

and got it worked on my board. Maybe you can give it a try and let me know your test result.

Forgot to mention that you need to change the u-boot destination too.

echo 0 > /sys/block/mmcblk0boot0/force_ro

dd if=$FILE of=/dev/mmcblk0boot0 bs=1k seek=1 skip=1 conv=fsync

Hi PKZ,

Maybe you can take i.MX6SL eMMC boot for reference. Hope this can help you ~~

Best Regards

Dan
