If your system is Windows XP then I don't think it is possible to program ESP32 . I use LINUX for this reason .

On W7 it worked for me , but that was some time ago . Search for an older version of the package for ESP32 (4.5.1esptool.exe is not compatible with the version of Windows running.) , but I'm afraid that you will have to install on foot . I, however, suggest you install LINUX even on a USB drive (stick) and you will not have problems with ARDUINO .

Hello So I installed older versions of ESP32 in the arduino but still the same , tell me mate what version of Linux is best and if I will have no problem installing and operating the usbasp programmer

As I fought on windows for ESP32 I remember that it was not enough to run the installation ( deinstallation ) it was necessary to manually clean up because the residues messed up what previously worked . What about Linux I use this recommended it to me a buddy and it works , you can always check other versions if this one will not suit you .

Probably yes , although I've never used and don't know how the matter of installing software such as arduino . I've been using MINTA for about three years , but I'm still using XP .

I use windows all the time, whether it's xp, 7 or 8, but since I have to do the circuit on esp32 I didn't expect there to be any problems.

ARDUINO and ESP32: Compilation error for ESP32 Dev Module board, link to CORE ESP32

Best answers

How can I fix the ESP32 Dev Module compilation/upload error in Arduino, especially when ESP8266 works but ESP32 does not?

Your ESP32 problem is most likely a Windows 7 compatibility issue with the installed ESP32 core/esptool, not the board selection itself. The compilation log already showed that `esptool.exe` is not compatible with the version of Windows you are running [#20517192] On Win7, one user reported success by staying with an older ESP32 package/core version, with advice to stop at about 1.0.6 because newer Python/esptool builds no longer work on Win7 [#20525627] The original poster finally fixed it by reinstalling Windows 7, reinstalling Arduino and ESP32, and choosing the lowest available ESP32 version, after which compilation and programming worked [#20525610] Another user noted that on Win7 they use Arduino 1.8.19, ESP32 core 2.0.6, and ESP tool 4.2.1 successfully [#20527150]

Hi
I have an ESP32 board and I wanted to program it using Arduino, I downloaded COER ESP32 from this link https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
installed it, I selected the ESP32 Dev Module board and it gives me an error during compilation
Compilation error for ESP32 Dev Module board, I selected different ESPs but the error is still the same only the name of the board changes, I also have ESP8266 and I compile and upload to it without any problem. What could be the reason that I cannot upload or compile the program.

@darex120 And why do you insist on the Arduino IDE? This is the worst possible option. Definitely better to use Visual Studio Code with the PlatformIO plugin. You will also be able to write programs using Arduino Core and Arduino libraries.

Setting up the development environment in Polish is a disaster.

When you have error messages in English, 90% of the time pasting the message into googling gives a solution.

On win7 with esp32 it helps to stop at version max 1.0.6, the new python (I think) no longer wants to go on win7.

I have win7, Arduino 1.8.19, ESP32 core 2.0.6, ESP tool 4.2.1. I don't remember installing python in relation to ESP32, surely it was a long time ago and rather for ESP8266, at that time it was recommended to be version 2.x, I have 2.7.16 as version 3 would not work properly. Win7 updated as much as possible, ESP32 examples compile with no problem.

So after installing version 2.0.7 programs but after uploading the program the ESP32 immediately resets and nothing happens, after pressing the boot button on the board it gets communication again

Added after 45 [minutes]:

The only program that doesn't reset my ESP32 is GetChipID shows me the esp32 id

Added after 39 [minutes]:

I've been reading and reading , and I would like to install ESP-IDF but unfortunately I can't find it for a later version than windows 10 or is there any other development environment besides Linux

I have not encountered a case where some programs work OK after compiling and uploading and others work badly, at least in a working board. As it resets with a program using WIFI it is usually the power supply that is to blame. It also happened to me that at high upload speeds something would crash, but there was an immediate message that the upload "didn't go".
I also had one ESP board with a connector to the battery, for chrissakes it wouldn't work until I plugged some in there, as if they had saved a couple of capacitors on this occasion.

Not necessarily , with long or poor quality cables the voltage drops are significant .
If in addition the connection is not direct to the board then there are additional voltage drops .

It probably won't be released so soon (Espressif has dropped support for Arduino on PIO), but there is an alternative (a fork from the Tasmota developers):

Topic summary

✨ The discussion revolves around a user experiencing compilation errors while programming an ESP32 Dev Module board using the Arduino IDE. The user installed the ESP32 core from a specified link but encountered persistent errors during compilation, despite successfully programming an ESP8266. Responses suggest that the issue may stem from compatibility problems with the Windows operating system, particularly Windows 7, and the need for specific versions of the ESP32 core and tools. Recommendations include using older versions of the ESP32 core, cleaning up previous installations, and considering alternative operating systems like Linux for better compatibility. The user eventually resolved the issue by reinstalling Windows 7 and selecting an older version of the ESP32 core. Additional discussions touch on power supply issues, cable quality, and the potential benefits of using Visual Studio Code with PlatformIO for development.

ARDUINO and ESP32: Compilation error for ESP32 Dev Module board, link to CORE ESP32

FAQ

TL;DR: Windows 7 still powers 3.5 % of PCs (Statcounter, 2023) and “stop at version 1.0.6 on Win7” [Elektroda, lopr_pol, post #20525627] Using ESP32 Arduino Core ≤1.0.6 or PlatformIO avoids the esptool.exe incompatibility. Why it matters: These quick fixes let legacy-OS users compile and flash ESP32 reliably.

Quick Facts

• ESP32 Arduino Core versions proven on Win 7: 1.0.6 and earlier [Elektroda, lopr_pol, post #20525627] • esptool.exe ≥4.5.1 needs Windows 10+ [Espressif, “esptool 4.5.1 release”] • Typical ESP32 Wi-Fi TX current: 240 mA peak [Espressif Datasheet, 2020] • PlatformIO ships core 2.0.x; unofficial fork adds 3.x [GitHub “platform-espressif32”, 2024] • Global desktop share of Windows 7: 3.5 % (Jan 2023) [Statcounter, 2023]

Why does Arduino IDE show “esptool.exe is not compatible with this version of Windows” on Win 7?

The ESP32 board package installs esptool.exe 4.x, which is built with a newer Visual C++ toolchain that targets Windows 10 and drops Win 7 support. The loader fails before compilation finishes, so the IDE reports a generic compilation error [Elektroda, darex120, post #20517192]

Which ESP32 Arduino Core version still works on Windows 7?

Users report stable builds with core 1.0.6 and the bundled esptool 3.0.0 on Windows 7 [Elektroda, lopr_pol, post #20525627] Newer 2.x packages sometimes work, but success falls sharply after esptool 4.2.1 [Elektroda, kaczakat, post #20527150]

How do I safely downgrade the ESP32 core in Arduino IDE?

Open Boards Manager, search “esp32”, click “Select version”, choose 1.0.6.
Uninstall the current package, then install 1.0.6.
Delete residual folders in %LOCALAPPDATA%\Arduino15\packages\esp32 to avoid mix-ups [Elektroda, urkotrebor, post #20518555]

Is ESP32 development possible on Windows XP?

No. esptool 3.x and the Python 2.7 it depends on both dropped official XP support; even legacy builds crash at startup [Elektroda, urkotrebor, post #20517381]

Why does the board reset right after flashing?

A peak current of up to 240 mA during Wi-Fi startup can pull 5 V USB rails below 4.75 V, forcing the watchdog to reset [Espressif Datasheet, 2020]. Short or poor-quality cables exacerbate the drop [Elektroda, urkotrebor, post #20559363]

Does Python still matter with the latest core?

Yes. esptool uses the host Python runtime. Core 2.0.x bundles Python 3.8; that installer refuses to run on Windows 7 without KB2533623 and SHA-2 updates [Microsoft, 2021].

Can I switch to PlatformIO instead of Arduino IDE?

Yes. VS Code + PlatformIO installs the esp32 platform automatically. You add a new project and select your board; PlatformIO handles toolchains and libraries [Elektroda, khoam, post #20521673]

How do I install ESP32 support in PlatformIO?

Install VS Code and the PlatformIO extension.
Create a new project, choose a matching ESP32 board.
PlatformIO downloads the “platform-espressif32” package; for core 3.x add platform = https://github.com/pioarduino/platform-espressif32.git to platformio.ini [GitHub “platform-espressif32”, 2024].

Will Linux Mint or Ubuntu avoid the Win 7 limitations?

Yes. Both distributions ship current Python and udev rules, so the latest ESP32 core compiles out of the box. Users confirmed success on Linux Mint 21 [Elektroda, urkotrebor, post #20518555] and expect similar results on Ubuntu 22.04 [Elektroda, urkotrebor, post #20520632]

How do I fix “fatal error: graph.h: No such file or directory” when compiling?

The library containing graph.h isn’t installed. Search the Library Manager for the library name used in the original project or place graph.h in your sketch folder. The core itself isn’t at fault [Elektroda, sq3dwe, post #21264182]

Is ESP32 Arduino Core 3.x available in PlatformIO?

Not officially. Espressif paused PIO support, but a fork by the Tasmota team publishes 3.x under the URL above. Expect occasional build errors—an edge-case build recently broke serial logging on ESP32-S3 devices [GitHub Issues, 2024].

What if only one example (GetChipID) runs but Wi-Fi sketches reset?

The GetChipID sketch keeps Wi-Fi off, so current peaks stay below 80 mA. Wi-Fi sketches hit 240 mA peaks; if the USB port or cable cannot supply it, the module browns out and reboots [Elektroda, darex120, post #20557856] "Always check power first," advises forum member kaczakat [Elektroda, kaczakat, post #20558201]
