Grand Central SDFat problems

by zzcrow on Sat May 22, 2021 8:53 pm

How do I get a 256 GB sd card to work with with an arduino grand central M4 express using sdfat wit built in card reader?? What arguments do I need to pass to init()? (Besides SDCARD_SS_PIN ) and speed?
I can get a 8GB card to work in the standard library of course, but it does not support anything past 8GB :)
I thought using SDFAT library would work with exFat formatting

Problem solved by.... me!!!!
sdfat library by Bill Greiman supports exFat , adafruit sdfat fork can not be installed at the same time, the fork does not support exFat!!!!!, If you want exFat support delete the adafruit fork!!!!
