Occuring boot error in android automotive 14 OS

[subash_p]

I'm trying to bring up the Quectel EC20 on my i.MX 8QXP custom board. When I added usb-serial.c as a loadable module in my kernel, some errors occurred during boot. I will share the errors below. However, no errors occurred when using Android Automotive 13 OS

[ 4.815790][ T1] usbserial: exports protected symbol usb_serial_resume

Hello,

Different carrier boards rarely require a different kernel unless there is some hardware on the carrier board which uses a driver. An example is that there are some serial UARTs as part of the SoC, and the drivers would be for that. There are usually other serial drivers as well. If you had a custom carrier board which has an implementation of a serial UART from some other unknown chipset, then you’d need a driver for that.

Hello,

Yes, none of the i.mx BSP include the driver that you need, in this case you will have to do it.

Hi @Bio_TICFSL 

I didn't added the usb-serial.c driver file externally it's an inbuilt driver file and also i didn't added any other driver file externally i just enabled these usb-serial.c to Module

Thanks,
