I often will pop into a commandline to quickly tweek an ESP32 project instead of bringing up the Arduino IDE 2.x so I created a Makefile to compile some of my projects and because of the SPIFFS /LITTLEFS issue of the missing IDE 2.x GUI tool I added the capability to the Makefile. You will have to t...

I've figured some things out and have a better working Makefile which now lets you select/set your filesystem partitioning type and it will also so the littleFS filesystem too. Have at it and let me know what you think. Just fix up the sketch name and a few paths. # # Usage: make build | flash | fil...

@Rulioht, that has nothing to do with SPIFFS support in the Arduino v2 IDE.
Please notice the subject title of this forum thread "Re: Arduino IDE v2.0.3 missing SPIFFS upload tool"

You should create your own thread with a subject related to your problem.

I've updated the Makefile and I use it now for both building and flashing the Arduino sketch and when I need to update the SPIFFS storage area. If you want a LittleFS image then change the MKSPIFFS tool to the MKLITTLEFS tool by commenting out MKSPIFFS line and uncommenting the MKLITTLEFS line: # # ...

Could you check the module on this board is ECO3 chip or no? If it is ESP32-WROVER-E or ESP32-WROOM-32E, please add a parallel resistor across 32768 crystal. The kit version I have is an ESP32-WROVER-E model. What size resistor goes across the xtal/GPIO32_GPIO33? I ended up making a OpenWeatherMap ...

You might try posting your issue with the github repo for the arduino-esp32 package:

Long in short: is it OK to connect an ESP via I2C to a MCP23017 running on 5V without any level-shifters? If you have 4.7K pullups to +5V then put 10K pull downs to ground will get you a 3.4V level which could work without level shifters. A quick test on an old Adafruit LCD shield(has MCP23017 onbo...

I purchased the ESP-WROVER-KIT v4.1 from Digikey and can not get the external 32.768 crystal to be accepted when I enable it with menuconfig. The output is always W (321) clk: 32 kHz XTAL not found, switching to internal 150 kHz oscillator I've tried deep sleep examples which programatically call ou...

It would really be nice to have more control of debugging levels, compiler error/warning levels and compiler optimization levels in the Arduino Tools menu. This is what I added to get those things but the 2.0.6 release of the arduino-esp, Arduino core for ESP32, does not provide that.

3 years later and still a PIA to figure out. I've tried 3 different tuning-fork type(metal cylinder) types with and without 12pf caps and can't get it started. So I'm down the same path, ie looking for the part used on the kit to see if that will work better.
