We are using a CC3100 in our board with SPI Interface.
Our problem is that the CC3100 does not respond anything in the MISO line. Our schematics is equal CC3100boost_sch_rev4p0-a.pdf page2.
Our signal are:
RESET '1'.
CLK = 6MHz Polarity = 0 and Phase = 0.
MOSI: Sended: 0x65 0x87 0x56 0x78.
INTR = '1'.
nHIB = '1'
MISO = Always '0'.
What do we need to verify activity (0xBA, 0xDC, 0xCD, 0xAB)??
One more information: Over UART we do not see a problem, we flash the SPI and read parameters of the CC3100R1.
