UART Serial port blocking mode fgetc function not able to fetch required data bytes

Hi,

I can't find any related past similar issue on blocking mode serial port uart.

May be you can try adding delay to the for loop if don't want to increase baud rate or iterations.

9600 baud rate means 960 bytes per second so meaning one byte takes about 1ms.

It takes about 2 iterations per byte so meaning one iteration runs at 0.5ms.

Therefore probably can add a 0.5ms delay to for loop. delay(0.5); / usleep(500);

Check this link there are some similarities.

Or may be can access the uart core directly via status register or control register for flag check this manual (Page 146).

Best Regards,

Sheng
