Uno's unable to upload via ISP anymore?

Hey everyone first of thx for taking the time to read this!

ok so i have a problem i can no longer burn bootloaders or sketches to my pro minis with my unos

i make ps1 modchips with the pro minis and iv done many so i know my wiring is ok i know my pro minis are ok as i can still program them with serial usb

ive tested with two unos same results

im at a loss...

here is my log dump via ISP

avrdude done. Thank you.

i know this is typical of bad wiring or bad chip but iv done 100's of successful uploads then one day it stopped working...

i make ps1 modchips with the pro minis

Wow! Is there still money in that?

oh kinda the real money is in the send-in service.

In recent times, usually the "one day it stopped working" problem with Arduino as ISP is this:

In Arduino AVR Boards 1.6.22 and newer, the protocol used for Arduino as ISP has changed from stk500v1 to arduino (and I can see from your output the arduino protocol is being used). This caused problems for some people whose Arduino as ISP worked fine without disabling the auto-reset before the protocol change. They may not have associated the problem with an update they did of Arduino AVR Boards or the Arduino IDE. The solution is to roll back to Arduino AVR Boards 1.6.21 or to put a 10 uF capacitor between reset and ground on the Arduino as ISP.

However, I don't associate the "Device signature = 0x000000" issue with the thing I described above. Even so, it's easy enough to give it a try just in case.

hmmm thanks for the info

what would cause Device signature = 0x000000?

here is a picture of my wiring

iv tested on 3 pro minis now all report

avrdude: Device signature = 0x000000

Generally 0x000000 sig indicates a wiring problem, or that the target chip is configured to use an external crystal but none is present. Since you say the pro mini's are working via USB, that eliminates the second possibility, leaving only one: Your wiring is wrong. I suppose it's also possible that one of the SPI pins (specifically MISO) on the programmer is blown somehow?

I'd be suspicious that one of your jumper wires is bad or something. Check continuity with multimeter on every pin (I usually do it from the pin on the microcontroller on the programmer to the pin on the target micro - this way, whether the problem is the wire, or a solder joint somewhere, or whatever - you'll catch it.

corpeder's pictures:



The system of poking dupont connectors into the holes on the Pro Mini seems very unreliable and inefficient.

Since you're doing so many of these, I recommend taking the time to make an adapter with conical tip pogo pins. If you want to get really fancy, you could make a full-on programming jig but even a simple adapter you press onto the board by hand will work well enough.

here is my wiring

and continuity check out so not my wires iv switched out the wires just to be sure

this is the schematic im using

iv even soldered connections directly

different mini, better wiring, same issue... probing with multimeter checks out.

welp im still looking for help if anyone still has any to offer...

thx
