C++ (Cpp) usbtty_poll Examples

Example #1

File: usbpoll.c Project: gitkyc/uboot

int do_usbpoll (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[])
{
	u32 i = 500;
	int ret = 0;

	if(argc < 2)
		goto usage;
	stop_polling = 0;
	xfer_error = 0;

	dfu_load_addr = (ulong)simple_strtoul(argv[1], NULL, 16);

	while(!stop_polling && (!xfer_error)) {
		usbtty_poll();
	}
	/* do usbtty_poll() for the DFU Class status request to complete */
	while(i && (!xfer_error)) {
		usbtty_poll();
		i--;
	}
	return 0;
usage:
	cmd_usage(cmdtp);
	return 0;
}

Example #2
