UART 0 & UART 2 Behave Differently
Beaglebone Blue - with a recent recommended Debian release
Below is Strawson’s example UART loopback program. With minor changes to read continuously.
I have attached an Arduino 115200 baud char output stream to both the UART0 & UART2 in parallel.
If UART2 is selected the stream will read as expected - maybe forever.
If UART0 is selected the stream will read for perhaps 30 seconds. The PUTTY cursor will flash and the program stalls until interrupted with a ctl C.
I suspect there is some conflict within LINUX?? If anyone has an idea about this,
it will be greatly appreciated.
