Not able to flash anymore

[dachoeks3]

I have run this couple of years ago and everything worked fine. I have set it up now and it compiles correctly but when I try to flash I get an error about 8m argument. I have tried to change it in Makefile but then it doesn't compile. Any idea what I'm doing wrong? I have installed latest esptool.py which I suspect is the issue.

Change 8m to 8MB?

[dachoeks3]

It doesn't compile then. Gives similar error. I can still compile it with 8m then manually flash it. It's just a hassle since making any changes to the code then flashing takes extra time.

Issue is old esptool version in this project.
