Part Number: CC2652R
Other Parts Discussed in Thread: UNIFLASH
Tool/software: Code Composer Studio
CCS Version 10.1.0.00010
Using the CC2652R Launchpad dev board I flashed the simple_peripheral_CC26X2R1_LAUNCHXL program which succesfully worked. I began removing the unnecessary GPIO and display sections via the syscfg tool so I could verify that the same chip on our custom pcb would work (We had already verified RF functionality through SmartRF Studio 7)
After these modifications the program still worked on the Launchpad but did not work on our custom pcb so I began looking into other parts that might be to blame,
Under Device Configuration I noticed a "Bootloader Backdoor" tied to a GPIO that was in use on our custom pcb so I disabled the bootloader and flashed the program. After this flash any subsequent attempts to flash the launchpad failed with the Error Code -241 "A router subpath could not be accessed. A security error has probably occurred. Make sure your device is unlocked." Nothing else had been modified which worries me because from research, this error code seems to be associated with the JTAG interface or flash memory being locked and the configuration for these have not been touched. Any attempt to erase flash, either through Uniflash or otherwise fails with the same code, however SmartRF Studio can still access and communicate which give me hope.
Any help would be appreciated
Thanks,
Joel
