TM4C123GH6ZRB: TM4E123G Task_sleep not working after adjusting project from TM4C1237

We have a product that we are trying to bring new firmware onto. A minimal test product was converted over from a TM4C1237 and now Task_sleep blocks. Worked fine before adjusting the project. Project does use TI-RTOS and driverlb.

    Hello James,

    I would look into pin out and clock configuration but really there isn't much detail here for me to run with. Also I am not deeply familiar with TI-RTOS so I am not sure if there is a change in Sys/BIOS that would impact this - I haven't heard of that happening before and what I know of the Sys/BIOS, I can't think of a feature that would change like that based on the silicon so it's probably a hardware level device configuration aspect that is causing something. Maybe another check is to make sure all the other code is running and Task_sleep isn't blocking because there was a hardware fault?

    Best Regards,
