Regression: EEPROM issue with official STK500 V1 FW -- avrdude 7.1 is okay but not 7.2 and 7.3 #1713

mcuee · 2024-03-02T13:58:31Z

Strange that this comes up again during my benchmark testing of STK500v1.

Using a STK500 v1 clone with official V1 FW on ATmega8535.

mcuee@UbuntuSwift3 ~/build/avr/avrdude_main/tools (main)$
 ./test-avrdude -b -d 0 -v -p "-c stk500v1 -P /dev/ttyUSB1 -p m328p Ubuntu_Linux_20.04" 
Testing avrdude version 7.3

The benchmark shows the wall clock time of avrdude carrying out the following tasks
  - Fl-ewv: erase flash, then write a sketch with three sections separated by holes, and verify
  - Fl-r: read the entire flash memory and write to file
  - EE-wv: write data to EEPROM with two data sections separated by a hole, and verify
  - EE-r: read the entire EEPROM memory and write to file

The sketch and data payload is roughly one sixth of the respective memory size

History of stk500.c

avrdude 7.1 release was on 2023-Jan-09.
avrdude 7.2 release was on 2023-Jul-20.

I will try git bisect (I do not know how to carry out git bisect properly, but I got the rough idea to do it).

stefanrueger · 2024-04-13T17:08:24Z

I will try git bisect

@mcuee any intell on what's going on?

Sorry I have not done anything on this issue yet. I will try to carry out the analysis next week.

@stefanrueger

Based on the above testing, git commit a3b7072 or PR #1272 is the culprit. Hopefully this will give you the hint on how to fix the issue.

Correct memory mode, delay and readback for classic parts #1272

Just to double confirm again.
