EV-LM3S811 port at 20MHz instead of 50MHz
Got the FreeRTOS port for the EV-LM3S811 working right out of the box! Amazing! I added a blinking LED task with no troubles, after reading through the excellent docs on the web site.
I noticed that the hardware initialization routine prvSetupHardware() sets the system clock to run at 20MHz by using the SYSCTL_SYSDIV_10 prescaler. Using SYSCTL_SYSDIV_4 would give 50MHz operation. I tried it and of course it’s not that simple. I suspect the timing of the OLED must be adjusted somehow – nothing appears on the display.
Just thought I’d ask.

The latest FreeRTOS download includes an updated driver for the display. Maybe that would help unless you are already using the V4.1.2 download?
