We are evaluating using some devices of the WPxxx family on a custom board .
We already have our own Yocto based Linux distro for different machines. Some features require the Uboot bootloader.
By doing a brief/shallow documentation search I couldn’t find anything about custom device memory partitioning or how to flash UBoot for an initial custom Linux bring-up.
On the link below it seems to be implied that the unbrick tools (swicwe, swiflash) are tightly coupled to the partitioning scheme depicted there (Fixed system “ro” partitions plus “rw” overlays).
I guess that the Linux BSP is on the “meta-swi” layer so using our own distro shouldn’t be extremely problematic.
Is it possible to use Uboot instead of “lk” with low/medium efforts?
Can the device memory be repartitioned (avoiding Legato, changing the rootfs to don’t be overlayed, adding partitions for the UBoot environment, etc.)?
