    I would still like to try doing it myself. Even if it means getting a reflow oven. In designing the PCB does anyone know the specs on the crystal oscillators? Is the 32.768 Khz oscillator just for the RTC?...

    Not sure if this is helpful or not but when I am dealing with Hex files for 4.0 I used the Arduino ide under Sketch click Export compiled binary. This saves a file to the folder containing that sketch. Was faster and...

    I understand about the bootloader chip. I still want to start designing while I wait. Possibly destroy a 4.0 trying to move the boot chip and 1062 to the prototype PCB. I guess ill have to do the 10x10 1062 if I do...

    Yes that would work if I was willing to leave the USB exposed. I fully understand I'm creating my own problem here. But what I'm after is a fully programmable and recoverable 4.0 with no USB input only can bus.

    In my case I'm using can bus to reflash not the usb. Im also not leaving the usb exposed. So my sketch erases the portion of flash then copys my new file in. During this erase reflash time is when I could have...

    The erase and copy is several seconds long. A power issue during this time period could cause issues right?

    Thanks, Frank, I do check my upload. But things happen and I would like a way to recover if something happens. Trying to avoid bricking my several hundred dollar gizmo.

    When I was playing with it I could increase the size to 0x50000 but I kept it at 0x40000 (256 * 1024) and just copied 0x40000 or less at a time until I filled half the available memory 0xF8000.
