That's what I had vaguely hoped, until the segfault occurred. > You could try filling in dummies for that into the config file. Yes, I tried that experiment already with 5.1, before moving on to 5.3.1. ;-) That removed the warning, so that "avrdude -t" started OK. However, programming still failed. The crash then occurred due to an error other than segmentation fault, IIRC. (I can recreate it tonight, if it's useful.) > I'm also attaching a temptative fix that reduces the number of > extended parameters to just the size of EEPROM in case PAGEL and BS2 > are not defined.

I looked for a core dump, to hook up to gdb, but either none was created, or I didn't look hard enough. (They used to just pop up in cwd.)

(I've never used that platform professionally or domestically. Ah, but all my colleagues have it, so I could try talking nicely to one of them. I'll then have a quick look for a link to the v2 firmware.) Grateful thanks for the patch, Jörg. I'll test drive it tonight.
