    Any way to check at runtime which version we have? Then we could filter to show only matching.

    ah, no change
    ESP32C3 OTA interface with file selection and Reboot button

    I guess the post fixes would need to be _2M.img/_4M.img but then how to catch both?

    Firmware file list for OpenESP32C3 with version numbers and 4M suffix shown in dropdown

    I don't see any evidence the 2 and 4mb builds identify themselves as such.

    ESP32-C5 are already available on ali, and they are rather cheap.
    Quite unlike ESP32-C6, where they were about $10 for several months after release.
    $2.16 for 1pcs ESPC5-12-N4, ESP-12F form factor. I ordered 2.
    $2.84 for 2pcs ESPC5-32E-N4 (bug?)
    https://aliexpress.com/item/4000894446707.html

    I just hope it is a release revision (v1.0), not beta (v0.1), as its support was removed from IDF.

    ESP32-C61 is in the same store, as T5-E1
    https://aliexpress.com/item/1005009543271108.html
    Description indicates pre-release version.

    Did anyone experiment with OpenThread? Perhaps using it, support can be added to ESP32-H2 and BL702. It uses IPv6 after all.

    How would BL702 support work? It's BLE/Zigbee.

    So far, I tested only BL808, it's dual core WiFi chip. SDK may be similar to BL602.

    OpenThread is 802.15.4 protocol, same as zigbee. But, it supports TCP/IP.

    I am testing OpenESP32 S3 on ESP32-S3-Relay-6CH. So far good, but I got reboot after saving pins.
    ESP32S3 pin configuration interface with relay roles assigned
    ESP_RST_PANIC
    Hm I can reproduce it by saving pins.

    TCA9554 is used to control relays of "industrial" Waveshare ESP32-S3-ETH-8DI-8RO module, so if we want to run OpenESP32 on it, then TCA9554 support is required.

    Added after 10 [hours] 14 [minutes]:

    ESP32-S3-ETH-8DI-8RO also crashes when saving pins, but pins are saved.
    Currently I am working with:

    TCA9554 driver has been merged and is enabled by default on 4MB ESP32.
    https://github.com/openshwprojects/OpenBK7231...mmit/e6dbea6007e414a9eb9ba7607cf71bde3691c752
    We can use now ESP32-S3-ETH-8DI-8RO with OpenESP32, however, the driver for RTC and Ethernet LAN is still missing.

    @insmod , I am preparing to add DMX512 protocol support, which is used to drive LED strips, just like WS2812. I will split WS2812 into "shared" driver and "backend", backend will be either SPI driver or DMX512. This, however, will require ability to send UART data from arbitrary pin on ESP32. I will be doing my tests on T-Can485 Lilygo, which already has MAX485.

    My question is - how's the UART on ESP32 currently, and how's the UART pin change API? Any input or thoughs on that? I can introduce it as well if it's needed.

    Well, uart send always worked.
    Uart receive, while it works now, it does so by polling in infinite cycle in separate task. Very inefficient.
    Pins are hardcoded for now.

    Added after 9 [minutes]:

    With a little more juice (second adapter 3v3 and gnd wired to the first adapter, both with ams1117) it boots fully and creates connectable AP.
    Wifi scan sees 5ghz networks.

    When AP is starting, power spikes to 1.4W/0.3A at 5V.
    So, about 0.5A at 3.3V. Don't know why AMS1117 on board is not enough.
    The board itself consumes about 0.04W/0.009A at 5V.

    I might have had somewhat similar issue with LilyGo T-Can485. Random brownouts on start and not stable WiFi. It was reproducible with multiple firmwares and on another site. The solution was to solder extra capacitor on the 3.3V rail.
    Close-up of LilyGO board with soldered capacitor and USB cable
    Can you try something similar? Just avoid too large capacitance as well... so you won't overload USB port. How your board looks like, which board model do you have?
    Helpful post? Buy me a coffee.

    ... wasn't C61 with only 2.4 WiFi?

    I'm waiting for the ordered C5 modules to test 5Ghz, but it'll take some time...

Topic summary

The discussion centers on configuring OpenBeken firmware for ESP32 devices with a default 4MB flash size using sdkconfig.defaults.esp32. Initial issues included missing sdkconfig.defaults.esp32 and bootloader offset misconfiguration, which were resolved to enable successful compilation and flashing. Various ESP32 variants were tested, including ESP32-C3, ESP32-C6, ESP32-CAM, ESP32-C2, ESP32-D0WDQ5-V3 (ESP-WROOM-32), and ESP32-S3, with reports on flash size detection, bootloader behavior, and peripheral support. Challenges encountered involved stack overflows on reboot, watchdog timer resets, and GPIO functionality inconsistencies, particularly on non-C/S ESP32 boards. Solutions included adjusting makefiles for 4MB flash, fixing bootloader offsets, increasing task stack sizes, and replacing software timers with hardware timers for improved timing accuracy. Peripheral drivers such as BMP280, AHT2x, DS1820, DHT11/22, PWM, UART, and NTP were tested with varying success; some required specific pin assignments or additional delays to prevent crashes. Deep sleep support was added without GPIO wakeup. The firmware uses the Espressif ESP-IDF SDK for ESP32 and plans for ESP8266 porting were discussed, noting SDK differences and RAM constraints. Continuous integration (CI) and online build availability were confirmed. Users shared flashing tools, partition table considerations, and debugging tips including esptool flash_id and efuse burning. The community actively tested and reported logs, crashes, and feature functionality, contributing to iterative fixes and enhancements.
