I was looking forward to getting started with my Raspberry pi 3B+ and iC880A-SPI, but it all went a bit wrong. After connection, my pi failed to boot even after the concentrator was disconnected, and I burned out two SD cards in debugging it.
So, I grounded myself before taking the concentrator out of its ESD protective bag. I connected the antenna to the concentrator, and then connected the two boards via dual female jumper cables for both the power and SPI connections following the “From Zero to LoRaWAN in one weekend” guide https://github.com/ttn-zh/ic880a-gateway/wiki (There were no boards readily available to connect the two and I was hoping to get the device ready in time to give a demo at a local hack-space). I triple checked the pinouts to make sure they were correct! Only at this point did I power up the pi, got lots of happy lights on the concentrator, but from then on no signs of life from the ACT LED on the pi which indicates SD card activity.
I wanted to see if anyone had any similar experiences or could point out any error I might have made - I’m keen to push ahead but reluctant to either cook another pi or buy a new concentrator if the current one is ok!
