I'll try. thanks for the fast answer.
I think i'll buy Samsung EVO MicroSDCard. Should i buy only 16GB? or can i use higher GB's SDcard?
64GB is MicroSDXC and 32GB is MicroSDHC and also same as 16GB is SDHC
The Problem is retry count exceeded... I don't know why is this happening to me. I search the older post the same problem, but i don't know what is the exactly problem.
My board is CubieTruck3 A20 Board and i use SD Card.
