Download the program & WDT

[summer]

HI, every one, I joined the watchdog program in application,i use sdk11.0, and i found the problem that when i download the program , the MDK compiler point out "error: flash download failed -cortex-M4". And i am commented out the watchdog program,the MDK compiler can download program to normal again .Why will appear this kind of circumstance?

Hi,

Is this the SDK example in the examples\peripheral\wdt folder?

Note that this example is not meant to be used with the SoftDevice. The example is by default placed in the same flash-region where the SoftDevice is located (at the start of the flash). If you in this case have already flashed the SoftDevice, you will either need to move the application above the SoftDevice region, or erase the SoftDevice with nrfjprog using the eraseall command.

hi,thank you very much.i use the the SDK example in the examples\peripheral\wdt folder, this method is more troublesome, I want to ask: are there any other way?What should I do?

Just use the following command: nrfjprog -f nRF52 --eraseall.

Or if you want to use nRF GO studio, just click on the erase all button:

After that you can flash the wdt example again using Keil.
