RE: Serial DFU fails validation

Hi,

The error suggests that after the image is received on the nRF52 side, the calculation (post validation) of the image received showing that the hash of the packet doesn't match with the hash in the init packet.

You would need to check if :

- The image you received and stored properly (read the flash out and compare it with the original image)

- Check if the calculation in post validation postvalidate_app() is correct

- Check if the hash received in the init packet is parsed correctly.

Please see Hung Bui's answer in this post.
