custom chip flashing

Use the DK as the power supply when programming the external board.

So do something like this.

But since you are using the 10pin connector,

here I have set up the nRF52833 DK and use it as a programmer to program a nRF5240 DK.

GND to GND connected on both boards. Black jumper cable.

VDD_nRF to VDD_nRF connected on boar boards, Orange jumper cable.

The red wire is just for shorting the current measurement P22 connector since I have that cut on that DK.

Regards,
Jonathan

Hello,

Please find the schematic and Part Number document.
Kindly check the schematic of the custom PCB and give your advice

Hello Madusha,

''Yes I provided external power. Please find the attached Image

Power supply = DIGILENT
Custom nrf chip = NRF52833-CJAA-B-R7''

It looks from the picture attached that you programmed your custom board by DK. The voltage supported by external debugging/programming is VDD voltage. Normally, this is 3 V when running from USB is the voltage level for custom board is as same as the voltage of DK?

I can not see any schematic here. Could you please upload your schematic file?

Thanks.

Kazi

Hello,

There is a duplicate case (+) nrf_52833 External chip flashing - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com) where I have been working on. I can close that one as you have uploaded the schematic here. I will give you a review lately.

Thanks.

There is no error log, but when I connect the custom PCB and SW-DP, the ID remains the same as when I disconnect it and connect the nRF52833_DK. Attached are two images: one with the custom board and one with the DK.

[quote user="Fernando@Madusha"]I tried with j-link commander as well but it did not work.[/quote]

Could you explain how the J-link commander doesn't work? Is there any error log?

Could you share the schematic of the custom board to your case nrf_52833 External chip flashing as my colleague required?

Yes I provided external power. Please find the attached Image

Thank you so much.

Did you provide power to your custom PCB? Not the power from the DK.

Could you post a picture of how you set the board with nRF52833DK?

I tried with j-link commander as well but it did not work.
But I tested my custom PCB with Arduino base BLE example it was worked(not included soft device by zephyr developed) it is custom BLE stack.

Thank you for your reply
So far I tried with direclty flashing via VS code and j-flash V7.58i tool
I will try with j-link commander tool.

Thank you

Yes, it's the same flow. Don't forget to also provide power to the external nrf52833 chip(custom) to make the Jlink commander detect it v3.3v, for example

Hi,

Does it possible to flash external nrf52833 chip(custom) via VS code ,nrf connect sdk extension using nrf52833 DK,(P19)
If yes
What is the procedure for that ?

Hi,

It doesn't need to add the SoftDevice controller .hex file. To program the NCS output build files to your device, which in most cases will be zephyr.hex or merged.hex.
