Recently in a project I am working on, I came across some issues with a program that was using an Arduino Bootloader. To isolate the issue at hand, it was decided to remove the bootloader and upload the code without the bootloader. Typically, on a build in Arduino IDE or Vmicro through visual studios, once an Arduino Project is built, a HEX file with the bootloader and without is created. When comparing the two files generated from Arduino IDE not much is different, as expected, since there is a bootloader and one without. However, when building the project on VMicro in visual studios, the hex outputs are not only wildly different than the Arduino ide outputs, but completely different from each other. This seems very odd to me, and I was wondering if this is an issue you could help me out with. Keep in mind I am using an alternative board file from minicore, to work with the 328pb chipset. This uses the Optiflash bootloader. I’ve checked and confirmed all the board settings in Arduino Ide and Vmicro are identical, and yet still completely different hex files are generated. Any advice on this would be greatly appreciated.

Thanks for the detail around this, it has greatly helped to isolate the problem.

We have identified the issue and we will update this thread when the fix is released in the coming day or so.
