Regarding Recover PCA10028

roger.k

Hi. I'm using PCA10028, SDK10.0.0, S130. Recently I'm testing SYSTEMOFF mode. Unfortunatly My board is not operate now. KEIL can't connect PCA10028 baord any more. Here's KEIL's log.

  • JLink Info: Found SWD-DP with ID 0x0BB11477 **JLink Warning: RESET (pin 15) high, but should be low. Please check target hardware.
  • JLink Info: Found SWD-DP with ID 0x0BB11477 ***JLink Error: DAP error while reading AIRCR / CPUID register ***JLink Error: Communication timed out: Requested 20 bytes, received 0 bytes ! Could not transfer JTAG data. Error: Flash Download failed - Target DLL has been cancelled

I thought the board had HW problem.

So I got new PCA10028 board which works well. But as long as i download my test code. It goes Halt.

Finally I think it's because i called SYSTEMOFF too soon.

I want to know "how can I recover PCA10028 board without KEIL compiler?" Is there any possibility to return default code like factory code?
