Other Parts Discussed in Thread: CC2340R5, UNIFLASH
Hi,
we designed a custom PCB including a CC2340R5 (RGE package). In parallel to the PCB design, we already started the software development using a CC2340R5 LaunchPad which works just fine.
Unfortunately, we are not able to run/debug any code out of CCS on our custom PCB -- neither our projects nor the example projects from the SimpleLink SDK. Flashing seems to work using an XDS110 (before flashing we first cleared the flash content using UniFlash and after that read the whole flash content to verify that at least something was written). After successfully flashing, CCS shows that the board is running but none of our breakpoints get triggered and our code does not get executed. The minimal code we flashed simply set a GPIO output pin to a high state. Unfortunately, we can not measure any changes at the GPIO pin. Of course we already tested different GPIOs.
However, we can successfully use the SmartRF Studio with our custom PCB to test some BLE functionalities like continous TX. That's why we assume, that from an electrical point of view, our custom PCB works just fine but the LaunchPad configuration of our project has to be adjusted for our custom PCB. We are not sure what configuration we have to adjust where. Can someone please give us a hint?
