esp32 boards location in Windows (partly solved)

[mahesh2000]

hi, on Windows 10, i found the esp32 board info in C:\Users\<username>\Documents\ArduinoData\packages\esp32, not at the location mentioned in the readme file.

[duff2013]

Did you use the Arduino Board Manager to install the esp32 core? That directory you show is usually where it is installed if you do manual install of the esp32 core.

[mahesh2000]

I used the boards manager. it's not a big deal, but i thought i'd make a note of it in case someone else had the same issue.

[duff2013]

I originally used that directory for the ulptool but later switched to the board manager location because that is where most people install the esp32 core. The current iteration of the ulptool will not work in that directory since certain items are not in the same relative location as the board manager install.

[mahesh2000]

do you mean that i cannot use ulptool since my esp32 core is in C:\Users\<username>\Documents\ArduinoData\packages\esp32? as it was automatically put there by the board manager, do i have any way out? thanks.

[duff2013]

Did you change where the board manager installed it? It's usually in C:\Users\<USERNAME>\AppData\Local\Arduino15\packages\esp32

no, i've not touched it manually. i'm running Arduino 1.8.11 on a Windows 10 machine. is there anything i can do? i don't know it helps, but here's are my preferences:

i kinda got it working in C:\Users\<username>\Documents\ArduinoData\packages\esp32 by making a few changes. It still won't upload when ulptool is installed; need to figure out why.

1. esp32ulp_mapgen.py needs to be moved to C:\Users\<username>\Documents\ArduinoData\packages\esp32\hardware\esp32\1.0.4\tools (or whatever your version is, instead of 1.0.4), otherwise error FileNotFoundError: [WinError 2] The system cannot find the file specified is generated. however, the location of this file in the esp32\1.0.4\tools location stops all programs, whether they have ulp code or not, from upload. remove this file and all is good again.
2. You must download and use binutils-esp32ulp-win32-2.28.51-esp-20191205.zip as per the instructions, do not download binutils-esp32s2ulp-win32-2.28.51-esp-20191205.zip as it has a different directory structure.
3. I'm using Python Version 3.8.1, so I had to make a few changes to the file esp32ulp_build_recipe.py:
   • changed print e to print (e). otherwise Python generated a syntax error.
   • changed print cmd[0] to print (cmd[0]).
   • changed the file type to "wb" instead of "w" as i was getting this error: TypeError: write() argument must be str, not bytes. with open(file_names_constant['sym'],"w") as fsym: to with open(file_names_constant['sym'],"wb") as fsym:

[mahesh2000]

got it working, i think. if the arduino project does not use the ulp, the esp32\hardware\esp32\1.0.4\platform.local.txt file must be removed. otherwise while the project compiles, it does not upload. if i figure any of this out, i'll post.

[duff2013]

Ok I'll check this out maybe they changed something in the esp32 1.0.4 platform.txt?

This has fixed the same issue I had with 1.0.4. Thank you!
