i asked pcb way 5 EVO plates to mount.
4 work perfectly.
1 of them gives me the impression that the port of SD card fails.
if I turn on the machine with SD card inserted you see the PIN2DMD logo but when the game graphics have to appear nothing appears.
if I turn on the machine without SD card, then the PIN2DMD logo and the game graphs without the color palette appears.
i've tried formatting 2 different SD cards and none of them works.
Would you know how I can check the SD card port or what's the problem?
