Your Kodi is crashing because of pvr.iptvsimple.so.3.9.8
It tries to unpack gzipped EPG data and crash. So you need to contact the addon author:
and finally, you use gxl_p212_1g_slowemmc, which is used for unsupported nand memory types (SpecTek MLC etc.), if this is the case, you have to compile the u-boot from odroid … or vims-pie branch. You also have to recreate FIP, for this you have to use original blobs bl2+bl21, bl30 and bl31, otherwise (most likely) you get the error “wrong chipid”, this is AFAIR hard coded in bl2.
If I use gxl_p212_1g, restarts and Kodi hangups happen more often.
When starting with microsd, the same situation.
