- SD 3v3 breakout
- Ethernet FeatherWing
XENON and ethernet work - no problems
SD card connected to MISO,MOSI,SCLK and D2 as SS. SdFat library used (from Web IDE) and using the sdformatter.ino example from the sdFat library to test.
When using card.begin(D2) it fails to find card. Ethernet then becomes unavailable and XENON either reboots or halts. (non responsive from Web IDE or console. Mode and reset have to be used to get it back into safe mode.
Have tried SS = A5 and D6 - same result.
Any pointers for me to try ?
