Is there an issue with series-2 chips HV programming?

Open lsellens opened this issue 7 months ago • 6 comments

I'm having issues when trying to program an ATtiny424 using a high-voltage (HV) programmer. Programming and setting fuses work perfectly without the HV programmer, but I want to experiment with some flags and need to test that I can recover from it first. I have used the same HV programmer on other chips from series-0 without issue.

However, when I attempt to set fuses or upload a sketch with the HV programmer, I receive the following error:

raise PymcuprogError("Unexpected number of bytes in response: "
pymcuprog.pymcuprog_errors.PymcuprogError: Unexpected number of bytes in response: 0 byte(s) expected 1 byte(s)
Failed programming: uploading error: exit status 1

This is with arduino ide 2.3.2 megatinycore 2.6.10 on linux
