No, I think the IDE version of AvrDude and more importantly the Configuration file has been modified to run with how Arduino IDE wants the bits set. The information from the later versions is superior in every way. I believe the IDE settings for the configuration file could stopping you from setting some of the Lock Bits. Notice the absence of other fuse access reads apart from what we requested it to do.

The above is straight from the command line batch. I think we can modify the paths to the later version of Avrdude and its config to solve this .

Hmm... i'm not so sure changing paths will work: The paths (to avrdude and avrdude.conf) that work on the imac are via the arduino.app . when i try setting the path to avrdude.exe in your unzipped directory, it won't run the .exe files. that's what i was trying previously. Unless i run them via 'mono'? Sorry - off to bed again - will have a think for tomorrow. |

Looks like the IDE config is setting Fuse Safe Mode. That means it will read the Fuses on entry, which your setup is doing, and reset any Fuse that change on Exit, once again seems to be doing that. I've tested a few ideas and the best way to do this is to erase the Chip. So don't wast time on trying anything else. Once you erase the chip, the Lock bits are cleared. These do not need to be programmed again. ERASE: -c usbasp-clone -p m328pb -P usb -b 57600 -F -v -v -U -e Then upload the Hex File again and it should be fine.  .

Progress 1st: I traced the problem on the WG30 power board (fault no output from one of the 12v isolated power supplies). I'm a bit embarrassed about it though.  Doh!  I must be getting old.2nd: I found a version of zadig ( V2.2XP) which runs under xp (the version 2.7 included the win32 driver, but zadig2.7 won't run on win32  . Once I'd run that and set the right driver, avrdudess2.17 could see the usbasp  So I plugged in the 2nd nano we've been trying to set the fuses on in terminal on the imac. Read the fuses and clicked the bit selector:-  So it looks like your imac command lines worked after all  and it was already right.I plugged in the 1st nano with just the hex file, that I didn't try setting the fuses on - and it's bitselector map was correct too Just as a sanity check, I plugged in a fresh nano - straight out of its wrapper. Checked the bit selector, and the lockbits were set 0xCF Tried to set them using avrdudess and got the same error I was getting on the imac yesterday:  Tried it a couple of times but the error seemed to repeat. So set the tick boxes to set lock when programming and uploaded the hex file. That seemed to set the lockbits : But I don't know how the lockbits got cleared on the original nano - unless uploading the hex file on the imac erased them anyway? No matter though - it looks like I can (finally) use either avrdudess on winxp or command line on the imac |

Great to find such an easy fix on the Power Board, although I bet you were secretly happy to find that pin floating  Yes that is common problem with programming the Lock bits, when you upload the HEX with standard settings, the Flash is Erased first. So, to erase the flash, the Lock bits are set to FF, after the upload, unless some other command is sneaked in, they remain off. I found earlier versions AdrDudess do not return/display the Lock and general status bits correctly. Normally you press each READ button twice (to be sure) and then press Bit Selector to display the results, but sometimes it's still incorrect The Important Fuse Bit is EESAVE, it must be 0, this preserves your Settings when you upload a new Hex file.

  I'm going to have to get back to winding the transformer I guess |

It's always a great feeling when all the effort and time we put in to assembling the Power boards and Controller produce what you hoped for Yes, the dreaded Toriod - The hardest part of my Toroid winding is finding three Very early Solar Inverters for the Toriods, no winding except for 14 turns of 2G cable through 3 stacked Toroids, which takes all of 10 minutes to wind  At least now you have the incentive to wind one NANO Inverter: Full download - Only Hex Ver 8.1Ks |
