Other Parts Discussed in Thread: CC3100
Hi
I am porting SimpleLink driver to STM32 MCU. I ported the host driver before but I haven't seen this. Can anyone please help with understanding the response from the WiFi module.
When connected to MSP development kit, the start sequence looks like this:
SPI Write 4: 65 87 78 56
SPI Read 4: bc dc cd ab
When running on our MCU, the first byte of the response is b9 instead of bc. I manually decoded the scope trace and verified that CC3100 is really sending 0xb9.
SPI Write 4: 65 87 78 56
SPI Read 4: b9 ....
Can anyone tell me what is causing this?
