I'm an ECE student at the University involved with a Research Lab and we've recently adopted the TM4C123GH6PM processor for our PCB designs. We're currently encountering issues with programming our first boards. Right now we're trying to use the TIVA dev boards to program our board via the JTAG. Below, I've posted images of the schematic I'm working on, the error from CCS when we attempt to flash the boards, the JTAG schematic from the JTAG programming guide(section 4.4) that we modeled our schematic after ,and the instructions we followed to use the dev board as a programmer(secion 4.5) .
We're kind of just stumped on what else to check. It seems like we've followed most of the documentation on designing boards using the TM4C so we currently don't have the impression that's it's inherently a design issue. The only thing we've soldered to the board is the necessary components to program the MCU(decoupling caps, reset button, and headers) ,and we're powering it with 3V3 directly(without the LDO). We've verified that the all the JTAG lines are pulled to the correct voltages and that the MCU is receiving 3V3. Any additional advice would be greatly appreciated.
