CCS/EK-TM4C1294XL: Unable to read peripheral registers on launchpads

Part Number:EK-TM4C1294XL

Tool/software: Code Composer Studio

Trying to see any register other than the core registers gives the error "unable to read". With launchpads, I get an error in the console that reads "CORTEX_M4_0: Trouble Reading Memory Block at 0x40013000 on Page 0 of Length 0x4: Debug Port error occurred."

I see this error on 5 PCs running CCS version 7.3 or 8.0

The attached image shows the error.

I also can't read the peripheral registers through a XDS110 debug probe. The target chip is TM4C129XN in this case. The console error is not printed out.
