Does anyone know if it is possible to use both serial ports of the board? And can we configure the baudrate of the internal UART? Thanks
The on chip UART can be configured in any way you want - it has 100% of the functionality you expect. All of the monitor commands work through the external UART. While it is possible to use both UARTS, you would lose the monitor capability, right? You would have to replace the EPROM with your own, or program the 251 chip.
...All of the monitor commands work through the external UART. Actually, the monitor will work with either the on-chip UART or the off-chip UART (16550). You may use both UARTS, however, as Tom pointed out, you lose the monitor if you do so. Jon
