Web Flasher

Thought I would give 3.0.0 a try on a spare ESP32 before committing to upgrading my main Waveshare device.
This board has 4MB of flash and no PSRAM so was trying to flash esp32dev-4mb.

Should the web flasher also update the bootloader and partition table?

It will flash the partition as it removes the old SPIFFS partition to make space for more code. note the 4MB is really tight on space and ESP32 without PSRAM don't have the BLE support as not enough RAM.

I'm certainly not an expert in the ESP field so a lot of the flashing technicalities go right over my head.

The board should have been erased before I tried to use the web flasher but it seems that it only wants to write the firmware (0x001000) which it does and then re-boots but then goes into an endless loop with the rst:0x10 (RTCWDT....... and invalid header messages. A quick AI search seems to suggest this is because it hasn't flashed the bootloader and partition table.

I cloned the V3.0.0 branch and I was able to flash esp32dev-4mb from VS Code no problem which is booting and working fine.

fixed on the web site now, thanks for reporting. If you want to repeat what you did to check it.
