Bootloader development on nRF52840

[Yashaswini S]

Hello,

I wanted to implement a bootloader on nRF52840 which is having 1024KB flash and 256Kb RAM. Can i get any link or tutorial on this if yes can anyone reply to this.

How can i achieve this in this nrf controller with detailed explanation or any libraries for this? How can i divide the flash memory for this so i am having all questions.

Thank you in advance.

Hi,

Can we use external Putty updating new firmware?

if yes, in that have to use mcumgr commands or any diffrenet commands are there?

Thank you in advance

Hi,

Putty does not include mcumgr support.

Hi,

Thank you for confirming,

We have to use only mcumgr command line for updating the new firmware?

Is there any alternative for the updating new firmware using external terminal like extra putty.

Thank you

See link above for an overview of applications with mcumgr support.
