Hi SHMoon,

Could you please give details of what the feature should be like? We need clear details in order to consider a feature request.

This function is needed for mass products in factories.

It is used by the operator to check whether the SW is correct.

So I hope this feature is supported.

By the way, a colleague pointed out that the .hex file format already includes a parity check for each line.
That will serve as some protection against file corruption, if that is what you are worried about.

For more information, you can refer to the Wikipedia article on Intel HEX: https://en.wikipedia.org/wiki/Intel_HEX.

Hi SHMoon,

It seems our tools don't integrate any such checksum features.

I recommend you keeping a checksum file coupled with your hex file delivery. When anyone use the file, they can run a checksum calculation, and compare it with the content of the checksum file instead.

You might have seen this method used in various software deliveries. An example is Ubuntu ISO downloads.

I will informally mention it with our developers as a feature request. However, please keep in mind that the tools we provided are meant as development tools and/or feature demonstration, so non-essential features might not be prioritized as introducing and maintaining them both require resources.
