Hello,

I am trying to program a WT51822-S2 by using the port 20 (SWD) of a nRF51-DK board. The connections between the module and the DK are the following:
- VDD : Module Pin 1 -> DK P20.3 and connected to a 3.3V pin on the DK.
- GND : Module Pin 11 -> DK P20.8 and connected to the P5.6 pin on the DK.
- SWDIO : Module Pin 21 -> DK P20.4
- SWDCLK : Module Pin 22 -> DK P20.5

So far the CM0 core is recognized. I can connect to the module, reset and halt the core, write and read its registers, without any warning or error.
Unfortunately the RAM does not work, I cannot erase or program the module. Did anyone had the problem before?

Best regards.

OK, I installed nRFGo and somehow it managed to "initialize" (???) the SoC by erasing everything. So far everything seems to work as it should.
