JTAG UART in no interrupt mode .... ie non buffered

Honored Contributor II

To assist in debugging, is it possible to configure the JTAG UART vie it's device driver to run in a non buffered mode , non- interrupt ...  

This would mean that the string to stdout would be processed immediately and not posted to a buffer where it is handled in parallel with the program flow. 

This way, if the program execution hangs due to a write or read to a bad address, the printf / stdio output will be in synch with the program flow ... 


I know there is a device driver that tells the stdio device it can time out if no "terminal" is connected .. so it would be something like that an ioctl call ... 




Thanks, Bob.
