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.
