CC3000 module corrupted

Ernesto Schianchi

Hi, we implemented in our products CC3000 and it's running fine, but we had a case where CC3000 module was corrupted, the module doesn't wake up it and the line IRQ doesn't change state.

It's very strange because day before worked fine, we haven't changed nothing in the firmware, it's possible that CC3000 corrupts itself if power off it during read/write NVEM function in the code?

Best regards.

Hi Ernesto,

Basically you should use the NVMEM APIs (accessing the EEPROM) that are meant for initialization, only during the initialization. Please have a look at the below thread, which would give you a high level idea as to which of the APIs would access EEPROM.

Please verify the same with the application that you are using with CC3000.
