I can prove it works fine.

I'm not quite sure what you mean by max, maybe you can write a bit more about the details?

I guess you are trying to provide larger value than the intended size, that will be limited by VALUE_SIZE.

Nah, it's something in the text file

Flags: 0x12, Size: 32, Min: 0x200, Max: 0x1000, Step: 0x0

And I agree with you, the only limit is the value_size!!

Nah, it's something in the text file

Flags: 0x12, Size: 32, Min: 0x200, Max: 6x1000, Step: 6x0

And I agree with you, the only limit is the value_size!!

Oh, that text describes the intended value range in the firmware setup.

This tool will only change corresponding value in settings storage, but how to interpret and apply the value depend on the firmware. So writing any value (within specified size) is valid for the tool, though it may be invalid for your firmware.
