I'm looking in the datasheet for timing data for SCI in UART mode. What's the maximum baud rate supported on F28004X? It seems like the datasheet just skips from the intro to SPI mode without any further data on UART mode. I found this related post fo...

I wonder if it's possible to unblock higher baudrates using different software? I highly doubt I will be sending more than a few kb/s of data via UART. The thing that bothers me is why J-Link keeps disconnecting? Any ideas? I will try to do the same thing on a Linux machine and...
