I have a strange issue that I need some help with. I have an SB72 with an RS422 device connected to UART0, and am using UART1 as the debug/monitor port. The device connected to UART0 is sending data at 4800 baud, and it seems whenever the device is physically connected, and I reboot the SB72, it hangs up in the monitor and never loads and starts my application. If I unplug the device, the SB72 boots just fine, and I can then reconnect my device and everything is working correctly. This is OK for my current development environment, but will not cut it for production.
I suspect that the monitor might still be looking at UART0, even though I've configured it to use UART1, and the incoming serial data is somehow confusing it and causing it to hang. Has anyone else seen something like this? Any suggestions on how to resolve the issue?
Thanks,
David.
