Great that you figured it out. And thanks for sharing the answer.

Hi Devs,

The problem was with the soldering of custom board. I followed the connection which Wojtek has mentioned. It is working now. Thanks for your support guys.

regards, vishnu

I am really sorry, but i have mislead you!

I am using 4 wires! Pin 1,2,4 and 5 on this picture. i forgot about Vtref

I have been using SWDap recently, and it did not need VTref pin, only SWDIO, SWCLK and GND. But Jlink does also need vtref

Hi Wojtek,

Are you sure the external device is programmed without connecting VDD_REF with VDD and GND pins(not GNDDetect)?

Because When I follow the connection you mentioned only the internal MCU is being programmed!! When I connect VDD and sending the recover command,I am getting the same error!

thanks

By mentioning GND, do you mean GND or GNDDetect?

RE: rigado BMD-300 with nRF52 DK

Wojtek — Tue, 18 Oct 2016 17:05:03 GMT

Yes, i am using only 3 wires and it works ok. I don't know how exactly it detects, but when i power up external board and it is connected as I said, it is programmed by DK. if it is not powered - internal MCU of DK is being programmed. So detection works ok. P19 pinout is standard 10-pin SWD connector - just note where pin 1is! You can find schematics on nordic website

I don't know about powering. I am powering my board from power supply. probably depends of current consumption

Thanks, Only 3 wires are required? how does the programmer detects the external chip then? Will it be able to detect using the GND? I didn't find the pinout of P19. can you please share the pinout details of P19 header, if you dont't mind? For powering up the BMD-300 module, Can I use the VDD and GND from nRF Dev board?

Wojtek — Tue, 18 Oct 2016 13:23:00 GMT

I tested that with my custom board, not the BMD, but i think that should be the same. I also dont have special cable, I just soldered 3 wires to the (GND, SWDIO, SWCLK) pads of the header. And remember about powering board you are willing to program.

RE: rigado BMD-300 with nRF52 DK

Vishnu Pradeep — Tue, 18 Oct 2016 13:19:31 GMT

Is it? I don't have a cable to connect to P19. That is why I go with P20. I'll give a try with P19.

thanks

Wojtek — Tue, 18 Oct 2016 12:49:14 GMT

I once tried using P20 as debug output, but I failed and never came back to trying again. I am using p19 with no problems. just connect GND,SWDIO and SWCLK from P19, power the BMD board and you are all set.

Hi Peter,

The connection is as below,

BMD-300 -> nRF52-DK

SWDIO -> SH_SWDIO (pin #4) on P20

SWDCLK -> SH_SWDCLK (pin #5) on P20

VDD -> SH_VTG (pin #3) on P20

GND -> SH_GND_DETECT (pin #8) on P20

The BMD-300 is powered by VDD and GND pin from the nRF52 Development board.

The schematic is attached to the question.

Could you upload a picture of your connections? And explain how you have connected them.

The BMD-300 has read-back protection enabled from factory. Use this utility to do a full chip erase. After that you'll be able to program it.

how to add files in comment box? I can't copy the content of log files either.

RE: rigado BMD-300 with nRF52 DK

Petter Myhre — Mon, 17 Oct 2016 13:26:41 GMT

Can you try adding --log argument and provide log.log?

Thanks,

I have connected BMD-300 module as mentioned on P20 header in Dev kit. I tried to do a device recovery using nrfjprog --family nrf52 --recover but got the following response.

  *C:\Users\USER>nrfjprog --family nrf52 --recover
Recovering device. This operation might take 30s.
ERROR: JLinkARM DLL reported an error. Try again. If error condition

Isn't this explained in the BMD-300 data sheet? And the nRF52 DK Debug output section?
