I have a Teensy 4.0 with the SD card holder sold here. SD seems to have no problem reading, writing, printing cardinfo etc on 32 gig sandisk microSd cards formatted FAT32.
Of course the SdFat I already had installed didn't work, so installed Mr. Grieman's beta-master. Nada. I cannot make any of his examples work. I'm dumbfounded. Is it possible that there is a speed toggle in there somewhere which is skeptical of my card's efficacy?
most of the errors I get running examples indicate inability to initialize or read card. 0X18 or 0x17 errors.
What should I look at?
I do need functions which SdFat has but SD doesn't.
