Error: Flash Download failed - "Cortex-M0"

Hi I am getting some weird response from my nRF51-DK.

Situation 1: When I try to flash it with the Blinky code (\sdk11\examples\peripheral\blinky\pca10028\s130\arm5_no_packs) it builds, and flashes successfully. But it does not run the code. I can not see the LEDs blinking. What is wrong? (In this case I have programmed the applicaition without a SoftDevice)

Situation 2: Now when I Erase all from nRFstudio, and program the SDK11 (s130_nrf51_2.0.0_softdevice.hex) and then flash the same Blinky application, it works. I can now see the LEDS blinking.

Situation 3: Now with the same SDK11, when I try to Flash the BLE Example (sdk10\examples\ble_peripheral\ble_app_proximity\pca10028\s130\arm5_no_packs), it does not flash and says: Error: Flash Download failed - "Cortex-M0"

I have seen this post: In the first part it says that your device might be in SYSTEM OFF MODE. I have pressed all the buttons and it doesnt help. Secondly, about the address mapping please see the screenshots below.

Please help. Thanks

Hi,

Scenario 2 is the only one that should work. In scenario 1 you will have the wrong target settings for IRAM and IROM and the code will not understand how to proceed. The same goes for scenario 3 as you have programmed a SDK 10 example over the SD130 v2.0 SoftDevice.

You trying to flash an example on top of a SoftDevice that it does not support. Please see the compatibility matrix. SDK 11 is compatible with SoftDevice S130 v2.0.

For a list of common IRAM and IROM setting please see the bottom of this blogpost.

Best regards,

Øyvind

Thanks for the prompt reply Øyvind. I have now used SDK10 with the proximity app and now it is working. Cheers. Problem solved.
