Hello everyone,
Could anyone tell me which pins are the programming pins of the nRF51822 chip for a QFN48 packet ? How can I program it on my custom PCB?
thanks..

If you want to use the Nordic nRF Go Studio software to program your chip (SofDevice, bootloader, application), you will need a J-Link (Segger probe). I would recommend to buy an nRF 51 or 52 DK and use the J-Link available on it to program your custom board, or you can buy a Segger tool.
I you are looking for another (cheapest) alternative, you can buy a ST-LINK/V2 probe. many of them are availanle at very low cost (~ 10$). Then, you can use for instance OpenOCD to program you chip, but this is not as easy as the Segger tools and you cannot use the software provided by Nordic.
No, the MK-20 dongle has no on board programmer. You cannot use it to program other boards. See my answer below.
Well, I am using MK-20 dongle to program bare nRF51822 chips with mbed the same way as if you have original readbear nano attached. No problem. Didn't use with debugger the same way like your J-Link, though.
Yes, I have a nRF52 DK on the way. However, I'm on a Mac so nRF GO Studio is not going to work. Can I just manually merge the .hex files using srec_cat.
Any comments on this Mac port of nRF GO Studio? sourceforge.net/.../
You can install the J-Link software for Mac in order to use the Segger probe.
You can srec_cat
to merge hex files, yes. To begin, my advice is to install the nRF5x-Command-Line-Tools-OSX so you can use the mergehex
and nrfjprog
tools directly.
I have no experience with Mac but I did the same on Linux.
