Arduino 1.8.13
Teensyduino 1.54-beta5
SdFat (Bill Greiman) 2.0.2
I'm trying to get the Adafruit SD card breakout board to work with a Teensy 4.0 with no luck. I'm using the following example with no changes:
Examples > SdFat > SdInfo
I've tried several cards and always get the following output:
SD initialization failed.
<snip>
SD errorCode: SD_CARD_ERROR_ACMD41 = 0x17
SD errorData = 0x0
I've wired as follows:
T4 <> AF254
10 CS <> CS
11 MOSI <> DI
12 MISO <> DO
13 CLK <> CLK
Vin <> 5v
Gnd <> Gnd
Should this work? Any ideas what the problem could be?
Thanks,
