UART bootloader for nRF52840

[mate15]

Is there a UART bootloader available for nRF52840? Doesn't have to be secure. Already searched in SDK 12.2 and 13 alpha, with no success.

Thanks for your help!

Hi Mate,

Serial bootloader will most likely come in SDK v13 next month. I can send you a preview version of it via PM. It's secure bootloader. I think for future proof, you should use the new bootloader.

If you want to use non-secure bootloader, you can think of using SDK v11 DFU bootloader which support serial. nRF52840 is not supported but for DFU it's not much different from nRF52832 except for size of flash and RAM.
