HEX Code

[Kent Liew]

Hi,

I would like to request the HEX code for part#nRF52840-QIAA-R in order to load the bootloader program into the chip.

Can you please help to check and advise?

Thanks.

Hi.

Which "HEX code" are you talking about? Are you talking about the J-Link firmware? Have you put your DK in bootloader mode?

If you have put it in bootloader mode, do the following:

1. Download this .bin file and place it on your Desktop, or some place easily accessible: J-Link OB-SAM3U128-V2-NordicSemi 170724.bin

2. Open the This PC folder.

3. Hold the button IF BOOT/RESET down, and switch the power OFF, then switch the power ON, on the device.

4. A folder named BOOTLOADER should now appear, drag and copy the file you downloaded into this folder (this folder will only be visible for around 30 seconds)

5. Power OFF and power ON your device, the device should now work.

Best regards,

Andreas

Hi Andreas,

I got the reply from my customer yesterday about the HEX code issue.

Please see the comment that provided by my customer in below.

"I have tried but when plugged into USB port, the dongle does not detect
so it is not able to go into Bootloader mode."

Please help to review and advise.

Thanks.

 If your customer uses a nRF52 Dongle he should take a look at this programming tutorial. It shows you how to put the Dongle in Bootloader mode and program it.

Best regards,
