"Error - flash download failed - Cortex M0

Stanley Wissmar

I get following message when I try to program with the Blinky project a nrf51822 chip: "Error - flash download failed - Cortex M0.

What is wrong?

    Hi,

    Thanks for the softdevice update. I

    (i). programmed this time around with the 5.2.0 version (s110_nrf51822_5.2.0_softdevice.hex) to be conservative. Programming was successful.

    (ii). Then programmed with Kiel the HRS demo. Now this time again (!) it did complain "Error - flash download failed - Cortex M0.

    I am very confused now. Thought the problem was solved. It must be something more fundamental problem. What is your analysis?

    Best Regards,

    Stanley

    Are you sure that you use the latest SDK as well, version 4.3.0? Can you please upload a screenshot of your project's target settings? You should make sure that IROM starts at 0x14000 and that IRAM starts at 0x20002000.

    If this is correct, and you still have trouble, can you please try to flash the application hex file using nRFgo Studio? Remember to use program application, not program softdevice.
