RE: Adding a prebuilt littlefs image to merge.hex image

DevinCallahan — Mon, 06 Apr 2020 16:38:43 GMT

objcopy doesn't quite do it. I haven't found a way to get the output ihex file to have its addresses offset to the location of the "storage" partition.

I did find "pynrfjprog" however which has a "write" method which can take a byte array, so I have a simple python script that can write the files in for now.

Thank you!

Hello

[quote user=""]1. Does someone know of a good way to convert a binary file into a ihex file that starts at a specified address offset (thus solving my problem directly)[/quote]

I think you can use arm-none-eabi-objcopy which is part of the arm gcc installation. To convert from binary to ihex you should do something like this

arm-none-eabi-objcopy --input-target=binary --output-target=ihex

[quote user=""]2. Does someone know of a tool I can use to just flash a binary file to an specified address (giving me at least some way to do this)[/quote]

You can just use nrfjprog with the memwr argument.

nrfjprog --memwr <addr>
