@TRS-80
Yeah it's all from pine64 store!
After a lot of testing last week!
Only one board is having trouble with kernel 5.x and we test all eMMC, everytime I use kernel 5.x with this board, we start having CPU error and "memory", but pretty sure the memory problem is coming from the processor.
Right now, the board is running with Kernel 4.x, and run pretty well. I will let it run for a while and after, will do the same thing with kernel 5.x but using a SD card, and will see if we are having the same CPU problem!
