Telit Modem Driver (CDC-ACM)

Other Parts Discussed in Thread: OMAP3530, SYSCONFIG, ADS7846

Hi All,


I wonder if anyone could help me with issue. I am currently working on custom board and developing Telit Modem Driver. The MODEM driver is only toggling GPIO line to turn Modem ON. When CDC-ACM Driver loads the port for the Modem when ON, I am getting error which relates to out of memory. As far as I know ICS is capable of Running on 256MB of RAM.


My Kernel Logs are here. Any help would be grateful on this. Its OMAP3530 processor.

This cycle is repeating all the Time

  • Just got that sorted out now. Did not have my GPIO Pin set as input to read the modem power.

    But I still get below out of memory error on two ports...

  • Dear Muhammad,
    Which type of modem are you using ?
    USB or serial (UART) ?
    If USB, did you enable USB modem driver ?
    I would like to suggest to remove the TELIT driver support (telit.c) in kernel and try.....tell me now the same kernel messages are you getting ?

    You need to enable the following support for modem.

    make menuconfig ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

    ----> Device Driver
    -----> USB Support
    ------> USB Modem (CDC ACM) Support
    -------> USB Serial Converter support ( I hope you have enabled this support )
    ------> USB driver for GSM and CDMA modems (You have to enable this also)
