Hi there,

I have tested this with a T4 I've been using as well as a completely new T3.6.

I have tried to use the EraseEverything which leaves me with "Unable to access SPI Flash Chip"
and RawHardwareTest leaves me with:
Code: 
Raw SerialFlash Hardware Test

Read Chip Identification:
  JEDEC ID:     0 0 0
  Part Nummber: (unknown chip)
  Memory Size:  0 bytes

Tests Failed  :{

The flash chip may be left in an improper state.
You might need to power cycle to return to normal.

I haven't modified the code, so I'm pretty stumped...

I'm on Mac, Teensyduino 1.53

Thanks in advance!
 
Whats the largest SPI Flash chip I can use on the T4 Audio board?
How fast would say 256kb copy over from an SD Card to the flash memory?

I'm making a banked drum machine that plays RAW files, and want to be sure that 10 RAWs could be played simultaneously from the SPI Flash, and that new files could be loaded from the SDCard onto the SPIFlash whilst the board is running. I hope that makes sense, thanks!
