These two are not similar issues Bilal.

The original thread is about unable to program the custom board on nRF5SDK based solution and your issue is unable to boot your custom board on nRF Connect SDK solution. These two are not same. Please open another ticket to get help from my colleagues on your issue.

hi Susheel Nuguru ,
I'm facing the similar problem. Can you guide me ? I'm flashing my Custom board which is using nrf52840 SoC using Nrf52840 DK. I'm able to flash the board but I'm unable to get logs print using printk() function also when I run debugger it goes into reset section(attaching screenshot ).
Looking forward to hear from you soon.

[quote user="arshdeep"]In nRFgo if i have only my DK powered up, i can see 2 regions, softdevice and application but if i power up my custom board also, It will give me only region 1, application. Does that give me some kind of indication that DK is able to detect my custom board ???[/quote]

It very much sounds like when you custom board is powered, then the segger on the DK is able to read the memory on your custom board.

Unfortunately no, This channel of devzone does not do Skype of any other calls. if you need faster assistance, then you can always ask your Regional Sales Manager to give you more assistance or set you up with an application engineer.

Yes I have nRF52840 chip on custom board and after your response i connected the GNDs of both the boards together but it still does not work.

I am now providing power to my custom board using a bench power supply . But still no luck .

I know that the antenna is not connected properly to the ANT pin of the chip. Should that matter at all while flashing the board ?

In nRFgo if i have only my DK powered up, i can see 2 regions, softdevice and application but if i power up my custom board also, It will give me only region 1, application. Does that give me some kind of indication that DK is able to detect my custom board ???

What kind of issues should I be looking for around here? I was really excited to receive my prototype boards but now i am just wasting time with no clue on how to proceed further.

Is it possible to connect directly with an application engineer on a call or Skype so that i can solve this issue asap.

Thank You !

You custom board uses nRF52840 chip? If not you should check flash segment (or address), softdevice version also.

Another thing (I used to be in the same case long ago), have you set the GND of your custom board and your nRF52840 DK together?
