Hi,
I run into a problem after programming the MCU TM4C129CNCPDT for the first time. The first programming is successful, but I keep getting the 'unable to access the DAP' error afterwards when I tried to reprogram it. I suspect there may be errors in the code keep resetting the device and prohibiting any access externally. I tried the methodS found on the forum:
1. short OCSIN and OCSOUT;
e2e.ti.com/.../ccs-launchxl2-570lc43-error-1170-0x0---unable-to-access-the-dap
2. keep pushing the reset button and retrying "connect to target" from CCS.
But I still cannot connect to the target after 100s times trying.
Please let me know if there is other way to recover the MCU and make it reprogrammable.
Thanks,
