Hey,

I tried flashing the latest nukihub on a brand new ESP32-DevKitC V4 from Aliexpress.

It finishes flashing (after long-pressing the BOOT button), but then after the reset is stuck in a loop showing this output every ~1s:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff

Here's the output of the Chrome DevTools from the flashing process:

Try hard reset.

I also tried flashing with the Espressif SDK CLI but it basically got stuck (I'm probably doing something wrong).

Any clue what's going on? Is the ESP32 I got not compatible (even though it shows up on the readme)?

commented

As far as I can see it's a regular ESP32 and it should be compatible. Did you try flashing a different firmware (e. g. tasmota) to exclude hardware problem?

commented

Tried flashing Tasmota/ESPHome and they both failed. I guess it's a busted esp32, thanks for the tip.
