Message: 93962

Hello,

I am trying to communicate with my GSM modem (Huawei E220) through USB. It gets detected with the following message

usb 1-2: new full speed USB device using isp1362-hcd and address 2

usb 1-2: configuration #1 chosen from 1 choice

usb-storage: probe of 1-2:1.0 failed with error -5

option 1-2:1.0: GSM modem (1-port) converter detected

usb 1-2: GSM modem (1-port) converter now attached to ttyUSB0

usb-storage: probe of 1-2:1.1 failed with error -5

option 1-2:1.1: GSM modem (1-port) converter detected

usb 1-2: GSM modem (1-port) converter now attached to ttyUSB1

usb-storage: probe of 1-2:1.2 failed with error -1

usb 1-2: New USB device found, idVendor=12d1, idProduct=1003

usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0

usb 1-2: Product: HUAWEI Mobile

usb 1-2: Manufacturer: HUAWEI Technologies

When I try to send it AT commands through Microcom it works absolutely fine.

But when I try to send AT commands through my own application (which is working fine on Desktop Computer) it kind of crashes with the messages from usb-serial.c shown at the end.

This happens when it reaches to fclose(FILE * ) line.

I am being unable to find its cause. Can somebody help me come out of this.

It something wrong with serial_write and serial_writeroom but what is that I dont know..

Regards

Guyz I need help...

I am able to receive and send SMS through the same board and Modem through Microcom.

I am able to receive and send SMS through the same application and Modem on Desktop Computer.

I dont know the problem, but I guess microcom is not using usb-serial.c or what.. Please tell what is going wrong I am writting a part of code just to give you people an idea. The code is communicating i.e. it gets the response but when I go to close the File descriptor it crashes uclinux...

Waiting for reply..

Code:

int send_mess ();

int main()

{

printf("Start :\n ");

send_mess();

printf("End :\n");

return 0;

}

int send_mess ()

{

int nbytes = 100;

char data_r[100];

FILE * serialDev;

char deviceName[15] = "/dev/ttyUSB0";

serialDev = fopen(deviceName, "wb+");

if (serialDev <= 0 )

{

printf("ERROR : Device Not Attached \n");

exit(1);

}

int datawrite=0;

char dataread;

datawrite = fprintf(serialDev,"AT\r\n");

fflush(serialDev);

if(datawrite<0)

{

printf("Error : %s \n",strerror(errno));

printf("\n No of bytes write :%d\n",datawrite);

}

do {

dataread = fgets(data_r, nbytes,serialDev);

} while ( strcmp(data_r, "OK\n") != 0 );

printf("END AT\n");

fclose(serialDev);

return 0;

}

Message: 93979

like ive already told you, that is not a crash. it is a *warning* just like the message says.

if you want to find out the source, *you need to read the code* that the warning already points you to.

you've never stated what kernel version you're using or how it is configured, so you're the only one with source that matches the kernel you're running and the kernel that is issuing a warning.

Message: 93981

Mike I am using 2009 Distro. It has 2.6.28.10 and it is not just warning message it is crashing uclinux.

After the following message it does reboot

SP: [0x034e59a0] <0x034e59a0> /* kernel dynamic memory */

and I have to load uclinux again.

I was seeing on kernel OOPS and there were similar problems reported there but I dont know they were exactly same or not..

While seeing source code, I was not able to figure out in which function it crashes. for that I used printf but it is not allowed in drivers therefore dbg is to be used. I currenlty dont know how to use that either..

Kindly help on this..

Regards

Usama Bin Shakeel

Mike I used printk to display the function name it visits and this was the flow. and after displaying a warning it stucks at the last line and reboots the system.
