I would like to make use of the GPIO expansion card.
To use a GPIO from the expansion card I have to use the activation command on the modem: “AT!FWD=GPIOCFG,42,OUT”. This AT command is available in the official SWI firmware, but not on my custom firmware.
The support of this AT command seems to come from the Legato “columbiaAtService” application.
My custom firmware is a build from the Fx30 sources 16.10.1.
The image generated from those sources does not contain the Legato “columbiaAtService” application.
Traces from my custom image:
root@Fx30-DrBox:~# cm info
Firmware: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06
Bootloader: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06
root@Fx30-DrBox:~# microcom -E /dev/ttyAT
Could you tell me how to build the “columbiaAtService” Legato application for my environment or provide me with the application package (columbiaAtService.wp85.update)?
Best regards, Christian.
