latest mergehex output fails to be programmed. mergehex 9.8.1 produces different hex than 10.12.1.

[kobyfr]

I have a project with app + SD + BL + Settings page, all merged using the mergehex tool

The mergehex was installed as part of the nrfutil package.

all is well when the mergehex installed is version 9.8.1. nRF Connect programmer and nrfjprog are able to load and program the hex.

When using mergehex version 10.12.1, both programmers fails to load the binary, with output : "ERROR Could not open HEX file: Error: Overlapping data around address".

looking at the output of the 2 mergehex versions, they are different. there seems to be a duplicate segment in the HEX file produced by mergehex version 10.12.1.

not al app+SD+BL+Settings page fail to load. I have different configurations of the same app, and only some of the resulting merge-hex files fail to program.

Hi,

It is a bug unfortunately. There was a similiar issue reported yesterday here in this post: https://devzone.nordicsemi.com/f/nordic-q-a/69940/nrf52840---problems-merging-and-flashing-secure_bootloader_uart_mbr_pca10056-and-ble_app_uart_pca10056_s140/286885. I'd recommend using an older version of the mergehex tool for now.

Is a corrected version available?

The issue has been resolved internally, but we have not published a new release yet. Please use the v10.11.x release for now.
