Hi there..
I've recently jumped back on development of a board I had made a while ago but have forgotten everything and am starting from scratch as computer was reformatted since then.
Goal: getting a custom program to program blinky example, also to erase and program softdevice and continue on to ble testing.
Problem: board is not programming, it currently has a blinky example on it already from years ago running unknown softdevice or with unknown sdk. at the moment i cant get the board to be recognized.
Here are the important points:
- I'm using SDK 12.3
- soft device 130 v2.0.1
- the development board i have is a nrf51dk pca10028 v1.2.0 2016.12
- the custom board i have uses a nrf51822 QFAC A1 (i believe this means its exactly the same irom and iram values as the DK but it is a revision 1?
- the board is hooked up to p20 on the DK P.4 SWDIO P.5 SWDCLK and using vdd and gnd on the board to power the device, and then holding p19-pin 1 high to enable p20 debug lines.
- the custom device also uses a 16mhz crystal and the internal 32khz, possibly that is not setup?
The dK seems to ignore the nrf51422 onboard the DK but i get errors such as cortex m0 not found or jlinkarm reported an error: aborting. and nrfgo studio doesnt recognize anything attached to the debug port.
I have a sneaking suspision that im using a SDK not supported by my revision? or my iram irom values are wrong or ive hooked up the debug port wrong.
my led is on p.03 so ive just changed the pca10028 pins to be sure it is configured before i make a custom board pinout and get that working.
any help would be absolutely appreciated, ive been swinging away at this for a week now and no luck.
