AVR32EA64 uploads once only
Opened this issue · 2 comments
A couple of issues. Firstly, I had to update Avrdude to a later version to get support for the AVR32EA64 - the provided one in DxCore doesn't work.
That done, I compiled, and managed to get a download, though I had to remove { program.verify } from the command tail as that seemed to break things.
So now it downloads (atmelice_udpi):

Thank you. The upload process has finished.
The issue seems to be:
1 byte of fuse5/syscfg0 written
avrdude: verifying fuse5/syscfg0 memory against 0b1100 1101
avrdude: 1 byte of fuse5/syscfg0 verified
The settings:
It looks to me like fuse5 is getting set wrong, in that bit#4 is UPDI enable, and that's getting reset, so you can't program the device again, at least not without HV programming (which I don't have support for)
Bit #2 is also suspicious, as that's "not used" in the datasheet.
I swapped the IC to verify this, fortunately I have a few spare.
Also: Anyone know how to do a HV reset on one of these parts? :)
I think the issue comes from here: [boards.txt#1609]
avrea.bootloader.SYSCFG0=0b1100{bootloader.resetpinbits}0{bootloader.eesavebit}
should be
avrea.bootloader.SYSCFG0=0b110{bootloader.resetpinbits}00{bootloader.eesavebit}
If time permits, I'll risk another cpu later today
I can confirm it works with the change above
