Hi,
I was trying to connect the modules to my raspberry pi 3B hoping to configure it with the uart shell. The raspberry, which is the 3B suggested model, has been flashed with the OS provided by Qorvo, specially because after configuring the anchors i would like to set one as tag and gateway to send all the data recording the CIRs.
Unfortunately, not matter what I’ve done, every time I run the minicom I cannot type anything. I do not know what to do. I attached my setup as an image: the module is on the pi 3B pins with the extended head.
These are all things I tried:
- be sure that the device is being recognized (sudo mdseg | grep tty)
- check the serial0 mapping (ls -l /dev/serial0, the result was ttyS0, after a few checkings I wrote in the /boot/config.txt a sentence to disable bluetooth (dtoverlay=pi3-miniuart-bt) and it got corretly mapped to ttyAMA0)
- check the uart interface was enable (in /boot/config.txt, enable_uart=1)
- disable the console (sudo systemctl stop serial-getty@serial0.service, sudo systemctl disable serial-getty@serial0.service)
- reboot the system after all the config and systemctl changes
- launch it with sudo minicom -D /dev/serial0 (and several variations, including baud_rate at 115200, the other mappings, etc)
I do not know what else should i do. Unfortunately, I’m a humble user and the j link device is too expensive for this personal project, so the modules haven’t been flashed with the firmware provided by Qorvo, they are with their original one, but as far as I know it shouldn’t be the problem.
Hope someone can help me, and thank you very much.
Mario.
