Dear all, I need to upgrade the kernel of some colibri modules.
Using u-boot is not an option but I can connect via ssh on that modules.
I think I have to use some sort of mtd device utility in order to write the module emmc, but I am new to this topic and I don’t know exactly the steps to do this. In my mind the steps are:
- copy the new kernel, device tree and the modules on the board
- install the new kernel and modules via opkg (installing the kernel is unnecessary, but is a simpel way to extract it from ipk packet)
- write the kernel uImage file on the eMMC (don’t know how)
- write the device tree on the eMMC (don’t know how)
Any help will be appreciated.
For further products could be a better choice to integrate the kernel in the rootfs? How can I change u-boot environment in order to do this?
