avrdude: verification error and other weird behavior Hey, I´ve just received a new hotend and everything went well until I wanted to plug in a cooling fan in the 12V pins. I'm working on Sanguinololu 1.3a with Marlin or Sprinter. Both firmwares worked before and I managed to heat it up one time, but while fiddling with the 12V pin I must have shorted the them resulting in my computer shutting down. What could I have burned or f**ked up with that? After I pulled out the fan the board connects normally again but the hotend thermistor show 109C constantly even when I pull the thermistor plug out. Trying to reupload the firmware (compiles normal) results now in Quote For marlin avrdude: verification error, first mismatch at byte 0x69ea 0x48 != 0x4a avrdude: verification error; content mismatch and Quotefor sprinter avrdude: verification error, first mismatch at byte 0x0002 0xf1 != 0x1d avrdude: verification error; content mismatch https://reprap.org/forum/read.php?13,363409,363409#msg-363409 Tue, 10 Mar 2026 15:17:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,363409,369842#msg-369842 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,369842#msg-369842 NoobMan Controllers Sat, 14 Jun 2014 12:32:02 -0400 https://reprap.org/forum/read.php?13,363409,369797#msg-369797 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,369797#msg-369797

The friend I got the USBasp from said he had managed to burn a bootloader with it, so does that mean my board is more broken then I assumed?

Update:
Despite the errors I managed something that looked like an upload of the GEN7 bootloader and fusesetting. Now arduiona can upload a sketch but the upload timeouts after 3-4 minutes.]]> sungod3k Controllers Fri, 13 Jun 2014 16:08:44 -0400 https://reprap.org/forum/read.php?13,363409,369427#msg-369427 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,369427#msg-369427 NoobMan Controllers Fri, 13 Jun 2014 15:31:24 -0400 https://reprap.org/forum/read.php?13,363409,369420#msg-369420 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,369420#msg-369420
I tried all the GUIs first but most of them dont support the ATMEGA1284p or I get the " cannot set sck period." error. Assuming I understand the function of sck period I would need to set it to 16mhz which AVRDUDESS isnt allowing me to because its not in the dropdown choices. Or is this an indication of another error?

With that I tried to do it with Arduiono. I tried it with libraries from maniacbugMighty, Optiboot and Gen7 which all results in the same sck error.

Then I tried it manually via command line with avrdude like its described in the GEN7 article. Here I cant get over the fact that avrdude doesnt want to recognize the 1284p in its library. I´ve seen codesnippets which appearently should add the 1284p to the conf but somehow manually writing in in the conf doesnt work or its the wrong code. Is there any way to import it correctly via command line?]]> sungod3k Controllers Fri, 13 Jun 2014 15:17:08 -0400 https://reprap.org/forum/read.php?13,363409,367387#msg-367387 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,367387#msg-367387

What do i need to do in order for the atmega1284p to show up in the config file?

I'll never understand why people look everywhere but into the RepRap wiki. It's there: [reprap.org]]]> Traumflug Controllers Mon, 09 Jun 2014 05:35:33 -0400 https://reprap.org/forum/read.php?13,363409,367289#msg-367289 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,367289#msg-367289 this page and from there try this one, and put it in that same arduino sub-folder where avrdude.exe is located. Afaik, it should work and should give those options including usbasp programmer (i think on that page says it needs net framework 2.0, not sure). Or try another version from there. Or try any other avrdude gui programs from anywhere else, perhaps some other will work better for you. Keep an eye out for the "erase" option, perhaps not all have that in a distinct operation.]]> NoobMan Controllers Mon, 09 Jun 2014 04:58:15 -0400 https://reprap.org/forum/read.php?13,363409,367202#msg-367202 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,367202#msg-367202 gist.github.com] but the -p dropdown in the GUI doesnt list it.

and also do i need to specifiy a programmer or can i just try them through?]]> sungod3k Controllers Sun, 08 Jun 2014 21:01:28 -0400 https://reprap.org/forum/read.php?13,363409,367197#msg-367197 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,367197#msg-367197 NoobMan Controllers Sun, 08 Jun 2014 20:25:47 -0400 https://reprap.org/forum/read.php?13,363409,366935#msg-366935 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,366935#msg-366935
avrdude: warning: cannot set sck period. please check for usbasp firmware update.
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

I checked with non arduino programmers as well and they both cant communicate or erase the IC which I interpret as being fried.
But at least i can save cost now and buy a empty IC at the electronics store.]]> sungod3k Controllers Sun, 08 Jun 2014 10:06:14 -0400 https://reprap.org/forum/read.php?13,363409,363897#msg-363897 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,363897#msg-363897 expensive than a new chip. But again if you dont have a programmer then you need a new chip with bootloader or have somebody else burn a bootloader on it.]]> NoobMan Controllers Mon, 02 Jun 2014 08:34:36 -0400 https://reprap.org/forum/read.php?13,363409,363854#msg-363854 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,363854#msg-363854 sungod3k Controllers Mon, 02 Jun 2014 06:45:02 -0400 https://reprap.org/forum/read.php?13,363409,363842#msg-363842 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,363842#msg-363842 Also could try erasing the entire chip with avrdude, reset fuses, with an icsp programmer that supplies its own power, preferably an atmel programmer. And then try re-upload after full erase.
If that does not work, hard to say, but probably the first diagnose is right. The above is just trying to make sure.]]> NoobMan Controllers Mon, 02 Jun 2014 06:09:03 -0400 https://reprap.org/forum/read.php?13,363409,363773#msg-363773 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,363773#msg-363773 sungod3k Controllers Mon, 02 Jun 2014 01:19:41 -0400 https://reprap.org/forum/read.php?13,363409,363733#msg-363733 Re: avrdude: verification error and other weird behavior https://reprap.org/forum/read.php?13,363409,363733#msg-363733
