Hi, we use a SD820 based SOM from a third party. We are thinking about migrating to Kernel 5.x from kernel 4.14 for the GPU temperature issue.
To boot the Kernel 5.7, it seems that we need to re-burn the bootloader. Using the flashall script, we updated the bootloader and then we were able to boot Kernel 5.7.
The question is, we would like to do what flashall does from within the Linux running on the SOM. This is because we need to provide an upgrade program to our customers and the systems at customer site don’t necessarily have USB connection needed for fastboot.
Is that possible?
