# AD9154 should give control of SPI to FMC when USB cable is unplugged,
|
|
# It's the case, but the PIC18F24J50 is introducing noise on SPI SCK
|
|
# (???) To workaround that, add 2 jumpers:
|
|
# - on XP1, between pin 5 and 6 (will keep the PIC in reset)
|
|
# - on JP3 (will force output enable on FXLA108)
