Modem will not go online
The modem responds but on trying to set it to register to the network via AT commands, it reports:
AT+CFUN?
+CFUN: 0
OK
AT+CFUN=1
+CME ERROR: operation not supported
Nicole and Eric report on Matrix that the W_DISABLE pin probably needs flipping, GPIO3_IO04. I see the following in librem5-evk.dtsi but nothing seems to make use of it:
pinctrl_wwan: wwan_grp {
fsl,pins = <
MX8MQ_IOMUXC_NAND_CE3_B_GPIO3_IO4 0x09 /* nWWAN_DISABLE */
MX8MQ_IOMUXC_NAND_DATA02_GPIO3_IO8 0x80 /* nWoWWAN */
MX8MQ_IOMUXC_NAND_DATA03_GPIO3_IO9 0x19 /* WWAN_RESET */
>;
};
Is there some generic way to set the output of the pin from the .dts?
