Other Parts Discussed in Thread: MSP-EXP430FR2355, MSP430F5528, MSP-EXP430FR2311, ENERGYTRACE
Tool/software: Code Composer Studio
While using the USB backchannel UART (MSP Application UART) connection, output to hterm is delayed while running in CCS debug mode. I observe immediate UART traffic from the MSP430FR2355 to the MSP430F5528 on the MSP-EXP430FR2355, but output to the PC over the USB connection is delayed. In some cases, the latency is up to 7-8s. Is there priority between the MSP Debug Interface and MSP Application UART that is causing the buffering delay. Operation runs normally when the device is in free-running mode.
Is there any way to get real-time updates over the MSP Application UART while using the Debugger?
I have attached example code based off of the OutOfBox demo. Pressing S1 should initiate an MSP Application UART transmission at 115200 baud.
Thanks,
Robb
