Hello,

No wonder you were not able to program the FW image, it's too big to fit on this part. I hope everything works once you get the correct module. Thanks for the update!

Hello everyone,

I borrowed another JLink from my friend and this time nRF connect for desktop-Programmer detected Jlink. The programmer is working well.

After that i realized the problem.

When i said Read in Programmer Aplication, device connected and i saw nRF52810_xxAA . I was shocked.

Our distributor sent me wrong device. :( same package but wrong device.

But i had ordered this one.

So i could erase chip and load softdevice but could not load bootloader in the past. I ordered new nRF52832 again. I hope that i can do it easily what i want.

I am going to write the result and then the subject is going to close like solved.

Hello again,

I used

> nrfjprog --program feather_nrf52832_bootloader-0.6.2_s132_6.1.1 --chiperase --reset

in command line.

ERROR: Unable to connect to a debugger.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.

I am getting confused. Could I have made a mistake in the installation?

I could not see Jlink in programmer for example.

By the way i am using this device in my custom board.

And I sampled for my board adafrfuit schematic.

Still i could not find a solution? Thanks for the replies Vidar again. really apreciated.

Best Regards..

Hello,

It should work with any J-link programmer. Does it not appear in the device dropdown menu in the top left corner? Anyway. Maybe you can try nrfjprog from the command line instead (nRF Command Line Tools).

e.g.

> nrfjprog --program feather_nrf52832_bootloader-0.6.2_s132_6.1.1 --chiperase --reset

Best regards,

Vidar

Hello Vidar,

I downloaded bootloader from your link too. Anyway i try tu use programmer app in nRF Connect for Desktop. I am adding hex file and see file memory load but there is another problem. It does not recognize my Jlink.

Select device says to me choose a Nordic Development Kit to your computer. My version is J-Flash Lite V6.86a. Maybe my version is older. So device part is not active.

I have worked a couples week ago with nrf52840 and everything is working well that time. But now i could not move forward.

If you want to my custom board i can send some pics.

Any idea for me again?

Best Regards..

Hello,

The feather_nrf52832_bootloader-0.6.2_s132_6.1.1.hex I downloaded from here: https://github.com/adafruit/Adafruit_nRF52_Bootloader/releases already included the Softdevice. Maybe that explains why you can't load it.

Either way, please try to use our Programmer app in nRF Connect for Desktop and see if you get the same result.
