"Error: Flash Download failed - Cortex-M0" after upgrade to SDK 5.1.0

Eliot Stock

Having just upgraded to the Soft Device 6.0.0 and SDK 5.1.0, I can no longer flash my nRF51822 from Keil. I get this in the Keil console:

Load "C:\\Users\\Eliot\\dev\\nrf51_sdk\\nrf51822\\Board\\nrf6310\\s110\\ble_app_proximity\\arm\\_build\\ble_app_proximity.axf"

I'm using the target nrf51822_xxaa_s110 (256K) in Keil and have check the memory addresses and I'm not trying to overwrite the soft device.

Have also checked everything in these posts:

devzone.nordicsemi.com/.../error-flash-download-failed-cortex-m0

devzone.nordicsemi.com/.../why-do-i-get-“error-flash-download-failed-–-cortex-m0”-when-downloading-a-project-from-keil

devzone.nordicsemi.com/.../uvision-reflashed-j-link-on-nrf51822-ek,-failed,-and-pca10001-no-longer-works

Here's my memory settings in the Kiel project:

rom start: 0x14000
rom size: 0x2B000
ram start: 0x20002000
ram size: 0x2000

I'm using Keil uVision 5.1.0.0 and have just installed the Segger driver from Setup_JLinkARM_V480.exe, including the CDC option.

    I've been chasing this around in circles for the last three hours and can't get it to work at all.

    I'm running Keil 5.1 and I get the same error when trying to flash a device. I have nothing under the Devices tab on the options for target nrf51822_xxaa_s110 (256k)... so it has no idea how to flash it (if I look under debug etc and the flashing algorithm its blank and if I try to add it's not found).

    I've installed the legacy support and then went back and forth and reinstalled the SDK in all sorts of order..

    This is amazingly difficult to get a simple SDK up and running.

    I just can't get it to list the nRF51822 device at all! Driving me slightly insane.

    Another cause for download errors is if you have a softdevice loaded in your device and try to program it with an app that does not include the soft device. Solution is to erase the chip (i.e., the soft device) then program with your app.
