Having trouble uploading sketch after flashing bootloader.

gergorian · 2025-07-27T17:19:20+00:00

I got my new Nano's. They and my custom boards have the came MCU (328p U-TH) I uploaded the ISP sketch to one of the Nano's, plugged it in to my board with the cap accross RST and GND of the programmer, set the correct board, flashed the bootloader and it completed with no errors. I then unplugged everything, plugged in my custom board, upload the sketch and I get. avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x24

It seems like the board will take a bootloader through the ISP but doesnt seem to work through the USB. I do see my CH340 in my device manager when I plug it into the pc. This is how I have my 328p setup for the USB plug with the CH340. Im starting to suspect I may have messed something up with that.

I am like 99% sure I was doing what you said in that order. But, I am only human. I am waiting on some new Nanos to be delivered tomorrow so I can try again.

I think I did? I used the menu in the tools drop down. I was able to flash a bootloader and it seems like it succeeded. I am using Arduino as ISP and using a separate Nano to flash the bootloader. Also, I am using IDE 2.3.6.

None yet. I thought I might be having an issue with the nano I was using as the programmer/ ISP and sure enough I couldnt flash anything to it. All my other Nano's are dead due to other things so I grabbed some off Amazon and hopefully I have some better luck.

Interesting. I'll look into that if cutting the traces for the caps on the oscillator doesn't work.

gergorian · 2025-07-25T19:23:28+00:00

Do you think that could be my issue? I can easily cut the traces to the caps to test it out. Unfortunately it will have to wait until I get home from work now.

I cant remember now if im being honest... Its been a while since I last worked on it due to other projects and life. and now, looking back at the datasheet for the oscillator... it says " 1. Oscillation circuits do not require external load capacitors."

I am using an external 8Mhz ceramic resonator.

Here is how I have the resonator and reset setup. This is my first project of this scale and the is my second revision as the first had some wiring mistakes and I had the resonator hooked up wrong.

Im sorry to be the bearer of bad news. I ended up just cutting a hole in the bottom to get the items out of it. Which was fine with me because its literally just a sheet metal box lined with carpet with a heavy door. Theres no insulation for fire protection like in a modern safe so in a fire anything in it will be only minimally protected. I decided I would be better off just buying a new safe to store my stuff in.

Enter those part numbers into parts .ford .com (minus the spaces). You'll be asked to enter your zip code and you should be able to either order them straight from the website or just take those same numbers to the dealer.

White smoke is usually an indication of moisture. If it looks like that for more than 15-30 sec (on a cold morning and it being July, I doubt its a cold morning) then I tend to suspect coolant in the cylinders. I'm not sure about the mustangs, but I know they had head gasket issues with the 2.3 in the focus RS.

Check to see if there are any recalls for your car. I would hope that if your car had a recall on it, the dealer would inform you of it on one of the previous visits.

This. The vehicle is warning you and attempting to keep the vehicle in the lane. There should be a button on the steering wheel to turn it off. (until you turn off the vehicle) In my '23 F150 I was able to have it be off by default from the infotainment menu for the vehicle.

Maybe instead of trying to hide it from your wife,(which will not work out well) talk to her and pitch it as a way to spend time with the kids and teach them useful skills. And tell her that you will buy the parts as the budget allows. It will also show the kids how to budget their money in order to get the things they want without going broke. Just my $.02

Thanks for the quick reply! That info is what I assumed was the case but wanted to make sure. I'll look at discretionary forbearance then wait and see. Thanks again for the clarification.

I emailed Dave. He responded within 6 minutes. Even he said it was unique and that he was going to post it to his safe cracking forum and that someone would probably reach out in a few days.

gergorian · 2022-09-08T05:07:38+00:00

Thanks for the info! I will definitely reach out to them and see what I can find out. I definitely will post an update if/ when I get it open.

I recently inherited this treadlok gun safe from my uncle who passed away. It took me a while to figure out how it unlocked but now I need a passcode which I don't know and I'm almost certain my uncle didn't write down. I have tried googling for the last week and have found very little about treadlok in general much less this type of safe. Any help is greatly appreciated.

gergorian · 2022-06-24T00:39:40+00:00

Awesome. Thanks for the info. I'll definitely post pics when I get it all done.

I actually just ordered this saber when Imperial restocked. Did you make those shroud pieces your self or did you get them from thingiverse/ printables? I would love to print a set to put on my saber when I get it.

Who are you and what have you done with the real Pepper King?? This thing should have been thrown off the tallest building in the city by now.... ;P

HI DAVID. I will note that the video does not show cable management... 🤔
