I'm trying to flash eddystone beacon example of SDK version 12.3.0 to this board ( https://www.robotics.org.za/image/cache/catalog/generic/NFR51822-MOD/NRF51822-MOD-000-650x350.jpg ).
It should be a Radioland product and use a NRF51822 chip.
Using openocd on Raspberry Pi Zero with raspbian I can download original firmware and I can flash it again succesfully using this command:
openocd -f interface/raspberrypi2-native.cfg -c "transport select swd; set WORKAREASIZE 0" -f target/nrf51.cfg
When I try to flash eddystone demo it breaks on "reset run" (see below).
If I upload original firmware, it works correctly.
I'm doing something wrong?
What can I do to indentify the problem?
This is what I do:
Open On-Chip Debugger
