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 Andrea,

I got an update from my customer and please refer to the comment in below.

As per customer :

I know how to program a nRF52840 dongle DK. The issue we have right now is that we had fabricated a nRF52840 dongle using Nordic's shared PCB files. This nRF52840 chip is totally blank and does not have the Open USB bootloader, how do we program the Open USB bootloader into our blank dongle and set the correct MBR as well? Any steps and Hex code for the Open USB bootloader?

The nRF52840 Dongle is shipped with an Open USB bootloader which allows it to be programmed without the need for a debugger. You do not need to understand the bootloader in order to use it, as most of the DFU related stuff is typically handled by the nRF Connect Programmer app. However, an application developer must be aware of the existence of the bootloader and adjust the memory layout of the application accordingly.

Can you please help to review and advise?

Thanks.

Hi.

The Open USB Bootloader shipped with the dongle can be found here.

I don't know how your custom hw design look, but you have to program the nRF52840 chip by for example using SWD pins, like I have demonstrated in this ticket.

Best regards,

Andreas
