Hello,

I have started with the TI-RTOS example fatsdusbcopy to evaluate file copy from SD card to USB Thumb Drive. After evaluating, I added Embedded Web Server into my project following httpServer example of Concerto Board (processors.wiki.ti.com/.../TI-RTOS_HTTP_Example).

After this, when I am trying to do the SD card to USB Thumb Drive copy, the task gets stuck when the function "USBMSCHFatFs_open" is called. During the development of the embedded web server, I was blocking this sdcard to usb copy task.

Can anyone suggest some way out?

Section of the code is shown here as provided in the example also:

// Mount and register the USB Drive
USBMSCHFatFs_Params_init(&usbmschfatfsParams);
usbmschfatfsParams.servicePriority = 3;
usbmschfatfsHandle = USBMSCHFatFs_open(Board_USBMSCHFatFs0,
USB_DRIVE_NUM,
&usbmschfatfsParams);

Thanks

Regards

What do you mean by stuck?

Do you incorporate the SD or USB Thumb drive with the HTTP Server?

Hello Todd,
Thanks for looking into the matter. In my program, I am using SD card to USB Thumb drive copy for which I am calling "USBMSCHFatFs_open" during initialisation. Once, this function is called, it will never return (that what I meant by "getting stuck").

Thanks

Can you export your project and attach it? When you export it, select General->Archive.

After removing the following lines in

pause_34567:
goto pause_34567;

I was able to get to the USBMSCHFatFs_open() call. It properly returned a handle.

Have you used the debugger to step into the function to what is happening? If you get a error that the USBMSCHFatFs.c source file cannot be found, simply navigate to the directory where it is in TI-RTOS (e.g. C:\ti\tirtos_tivac_2_01_00_03\packages\ti\drivers).
