Can't program bin file - Githubissues

Hello Edgar,

If you tried flashing with the latest python tool from master It is likely that the file flashing function is broken. See the commit master:9d2578f492869edaaa57abbfff83823f0b5dd0c3

commit 9d2578f492869edaaa57abbfff83823f0b5dd0c3 (HEAD -> master, origin/master, origin/HEAD) Author: Joeli Pikkarainen @.***> Date: Fri Jul 3 00:59:03 2020 +0300

Migrate to python3

py-flash-file not working, currently

If you check out a commit before the python 3 migration commit you might be able to flash the file. (Offcourse use python 2.7 env then.)

I also added new branch development that had some changes to the latest master, dont know if it made it work but you can try if you like.

I don't currently have the required hardware to test the setup. But if you send me the logs again I might be able to help you troubleshoot.

Message me back about your results.

Br, Joeli Pikkarainen

Hello! Thanks for this project, I wired my Mega in 10 minutes and successfully read/wrote the AT28 chip using the test function.

I have some difficulties flashing a bin file, that is like this:

~/Descargas $ hexdump rom.bin 0000000 ffa9 028d a960 8d55 6000 aaa9 008d 4c60 0000010 8005 eaea eaea eaea eaea eaea eaea eaea 0000020 eaea eaea eaea eaea eaea eaea eaea eaea * 0007ff0 eaea eaea eaea eaea eaea eaea 8000 eaea 0008000

All I get from the flashing is zeros, even if it apparently detects the data OK as seen by the data interpreted, i.e addr 0 data 169, corresponds to A9 addr 1 data 255, that corresponds to FF addr 2 data 141, that corresponds to 8D etc.

see here the output: https://hastebin.com/ajoqocezis.yaml


what am I doing wrong? Thanks a lot in advance :)

Thanks for your answer Joeli :)

I tried the develop branch, but I need to go to python/old for it to run, the command-handler.py in the python folder is almost empty, and it has a dash, and not an underscore.

When runing from python/old folder:

It hangs at address 23!

Then I do a read-eeprom, and it is all blanks.

The write-test runs well, it fills the first bytes with 0, 1, 2, 3, 4, etc, and I can read them back again.

I have flashed the firmware in the develop branch!

I will try to test with the previous 2.7 python version, but I need to set up the environment, my distribution does not have pip 2.7, so I can't install pyserial 2.7 :/

I will report back :)
