kernel crash on wifi initialization - javier.pb - 12-30-2020
I've been playing with the pinetab, in an attempt to get the u-boot startup shown in the screen, and in the way I've apparently broken the wifi/bt in kernel. The heading lines of the two cores are below. Out of those pieces, the system can be used with any extra problems.
What I've been doing basically was around u-boot, the pinetab specific device tree(s) and megous kernels (plus p-boot), and although all of them are potential causes, at this point my believing is that I might have done something on the wroing mmcblkX device, based on a comment on ubports boot.scr ("wifi takes /dev/mmcblk1").
Any ideas (or even trial solutions)
I've seen this on ubports on eMMC and mobian on SD (both previously working). Tried also to use content of linux-firmware from megous with no success (same than ones on ubports eMMC). At some point, I've been able to boot ubports with megous 5.10 kernel with same result.
