ConnectCore 6UL Express OS/firmware upgrade/installation failed!

+1 vote
Hello,
https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.0/cc6ul/yocto-gs_t_set-up-hw_6ul#ConnectCore_6UL_SBC_Express


I tried to update the OS/firmware of my "ConnectCore 6UL SBC Express" to DEY v3. I followed the normal method of micro SD card as I did to DEY v2.4 and v2.6. However, the process failed. It seemed that the u-boot loader was corrupted. So I tried to recover the u-boot loader with the Linux UUU method and it was successful.

Then, I continued to update from scratch to install DEY v3. I booted my "ConnectCore 6UL SBC Express" to "Recovery Mode" and tried to install from micro SD card. However, the command did not respond at all. It simply showed once more:
=> run install_linux_fw_sd
=> run install_linux_fw_sd


Then, I tried the USB storage method by running:
=> run install_linux_fw_usb

It showed that these files were not found! Actually, they were saved in the USB drive!
core-image-base-ccimx6ulstarter.boot.ubifs
core-image-base-ccimx6ulstarter.recovery.ubifs
core-image-base-ccimx6ulstarter.ubifs


I then tried this command:
update uboot mmc 0 fat u-boot-ccimx6ulstarter.imx

It reported that it could be saved to RAM.


So, how do I correct this and install DEY v3? Is my board dead already?



Thanks for any opinion.

try formating your SD card again and make surethe filesystem you select is FAT
what error are you getting after:
update uboot mmc 0 fat u-boot-ccimx6ulstarter.imx
Please provide the output of the following commands
env default –a
saveenv
reset
mmc list
mmc info
mmc dev 0
mmc part
ls mmc 0

This is a known issue with u-boot for cc6ul starter board on dey-3.0r3. We are in the process of releasing de-3.0r4 where it is fixed. It might have already pushed to git , so if you update your Yocto

~$ repo init -u https://github.com/digi-embedded/dey-manifest.git -b zeus
~$ repo sync -j8 --no-repo-verify

you should get the latest version of u-boot with fix.
