I followed OpenEmbedded Core article and was successfully able to generate a console image.
EC25 when connected to the with the board over USB with above built default linux lists all tty interfaces where in ttyUSB2 and I am able to execute AT Commands.
$lsusb Bus 001 Device 002: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
I wish to add support for EC25 Operating in USB QMI mode. (libqmi) (https://www.quectel.com/UploadImage/Downlad/Quectel_WCDMA<E_Linux_USB_Driver_User_Guide_V1.8.pdf)
- What should be the steps to get this module working in QMI mode?
- Does the kernel need to be modified as per the guide from quectel if the module is being detected and only libqmi etc needs to be set. ?
