So , you don´t think it´s possible to use the default bootloader and just have another PC software ?
Or is it just easier to make both yourself ?

Do you know if you can get the code for a better bootloader somewere if that´s requied ?

The software you wrote, it itr something that can be bought somewhere or is only used by you ?

Would be great to speak to you. Can I reach you outside this forum ?
