CC2340R5: Problem flashing a blank device with Segger J-Link

Tool/software:

Dear TI team,

We are having devices with the CC2340R5 MCU for Bluetooth functionality and they should be coming blank from the factory. Yesterday I tried to flash a blank CC2340R5 through Segger J-Link, but it failed as it failed to erase the memory. Then I flashed the device by using Uniflash and a XDS110 debugger and after that I had no problems doing the flashing with the J-Link. My questions are - could you give me any idea why the initial flash through J-Link? Why did it fail to erase the memory? Can I fix this and how? I'm attaching a log from J-Link and the CCFG (in Intel HEX format) of the blank device.

Hello Hristo,

Thank you for your patience! After looking into this, we were able to see this same issue. Unfortunately, J-link is a third party tool, therefore we can't provide an immediate fix, other than initially flashing the device using Uniflash. We have notified Segger of this issue, and hopefully it'll get resolved soon!

Best Regards,

Tarek
