Compiler/CC2650: BLE and Compiler Issue with Project Zero

anon130239048

Part Number: CC2650

Tool/software: TI C/C++ Compiler

Hi,

I am using the CC2650 LP Debugger (XDS110 Out) to program my custom board which has the CC2650.

Currently CCS is showing that I have successfully loaded a program even though my JTAG_TDO and JTAG_TDI connections are not there. Therefore, I can't flash a new program onto the chip even though it says it has been flashed.

I tried to completely erase the chip using Flash Programmer 2. I could not erase the chip nor could I flash what I wanted onto the chip.

For example: I have simple peripheral flashed onto my chip. Now, no matter what app I try to flash to my chip, I am only getting the simple peripheral application.

This problem was not occurring before and I have no idea as to how to fix this?

I suppose you can flash the same application to the launchpad using CCS, but not with your custom board, is that correct? Is your JTAG configured to use cJTAG (2-pin) mode? Also, so you have TCK and TMS connected?

Yes exactly.
I have tried with both cJTAG 2-pin and the standard 4 pin mode.
On CCS, it does show that the program has successfully loaded but the sniffer shows otherwise.

Arsh, it's seems odd that flash programming would be successful if it wasn't written into flash. Can you enable full flash verification in CCS target configuration file properties?
