OK, finally got the Luminary Micro LM3S811 evaluation board going... wrote 10128 byte from file /home/rfbrown/projects/Luminary/qs_ek-lm3s811.hex in 9.243969s (1.069954 kb/s) That's pretty awful! I'm sure it used to be better? Anyway, it's a non-STM32 Cortex part as Øyvind requested. I've attached the config file that I'm using.
