Hello All,
I have been working with the Tiva C launchpad, attempting to get the Tiva C - SPPDemo (NoOS) running on the CC256xQFN-EM. To do this I have the EM Adapter Boosterpack. I have populated the 32K slow clock - PN: ASVK-32.768KHZ-LJT
I have followed the process to create a new workspace and imported the SPPDemo project making the following changes:
Changed the build to be for DK-TM4C123G: PN_TM4C123GH6PM
I have altered the following in files:
BTPSVEND.C:
Added :

I also Altered the LED signal pin in HALCFG.c for PF2
The project compiles fine (with 4 warnings).
The output on Hyper term is:
OpenStack().
Stack Init Failed: -4.
Unable to open the stack.
As you can see the nShutdown/Reset occurs but the HCI_RTS does not go low:
SloCLK signal, not sure if the is an issue because of ripple on the clock edges:
I have spend ample time going through an checking everything and researching others posts but seem to be at a roadblock here.
Can someone please provide some guidance here.
