Hello.I 've got such problem with flashing some of the ESB protocol examples of NRF5 SDK.I use Adafruit Feather NRF52832 board with ST-LINK V2 debugger.https://www.adafruit.com/product/3406I work in Keil 5 IDE.When Ii try to load some of BLE examples (Periph Blinky, etc.), everything is ok. First I flash the Sortdevice and than directly an example.App works no problem.But when I try to flash ESB examples (like ESB low power prx) I've got such error.
I use default flash algorithm in debug settings.But once when I change smth I got it flashing, but than I again try to flash SoftDevice and BLE and after that again can't flash ESB...Any ideas what am I doing wrong?All my best.Ivan.

So you're going off-piste with that
life's a lot simpler if you stick to supported tools!
Anyhow, the first thing to try is always to do it via the ST-Link Utility - that way you can see if it's a fundamental issue with the ST-Link, or something to do with Keil ...
Did you remember to erase the chip before you programmed the example?
Use this nrfjprog command before you try to program it:
nrfjprog isn't going to work with an ST-Link - is it ?
So flash erase via Keil doesn't seems to be correct?
again, have you tried with the ST-Link Utility - to rule Keil out of the issue?
