Can't upload compiled sketch with bootloader: "verification error; content mismatch"

Development Tools Uploading
1

Hello,
I need to put another bootloader on my Arduino Pro Mini (3.3V / 8MhZ) to make OTA updates possible.

I followed this tutorial (Software / Flashen | AskSin++ only in German, sorry). Basically what I did is I compiled a sketch, then downloaded the bootloader from AskSinPP/bootloader/avr at master · pa-pa/AskSinPP · GitHub and created a *.hex file that contains both the bootloader and firmware.

I am using an Arduino UNO as ISP Programmer.

Uploading only the compiled sketch (without bootloader) works:

This are my settings:

I also tried changing fuse settings with avrdude, same problem:

What is wrong, why can't I change fuse settings or upload another bootloader?

But uploading normal compiled sketched works, so the ISP Programmer (Arduino UNO) should work correctly. I also tried another Arduino Pro Mini, same problem.

Will it allow you to just read the fuses?

I have a dragon programmer, when I get strange results, it's usually a wiring connection problem...

It did think it read 0 for the L fuse... Did you modify any of the fuses previously?

I don't think it would try to write if the fuses were set wrong, so I'd check wiring and make sure everything is connected... is this on an UNO board or a bread board 328p.?

:smiley_cat:

Reading lfuse / hfuse seems to be working. As I wrote the Arduino Pro Mini 3.3V / 8MhZ is connected to an Arduino UNO (used as ISP Programmer)

avrdude.exe done.  Thank you.

hm, what I can see is that the verification error is always at byte 0x7e00.
Is this the address where the bootloader code starts ?

Can it be that I got a batch of Arduino Pro Minis where the bootloader is write protected? Is something like this possible?

Can I debug this somehow to make some progress?
