I try to use the MQX MFS to save file in task_a,and the SD card and MFS are init in task_b, when the program goes to error_code = ioctl(filesystem_handle, IO_IOCTL_CREATE_SUBDIR,(uint32_t *)file_path); the program will stop, what is the problem?
I'am using my own borad and the MQX 4.1, both are tested to be ok.
Hi
I think the two tasks have different context, I don't see your code but I suggest you check the input parameters, filesystem_handle, is it a valid pointer?
