original PR #5278 from @s-hadinger, which is not accepted because of failure of CLAassistant `ESP.getFlashChipSize()` always returns `0` on Esp32c3 due to a change in the Flash layout. It looks like to Espressif documentation was not updated accordingly. https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/storage/spi_flash.html#spi-flash-size - Esp32 and Esp32s3 have the flash information update by esptool.py and decribed here - https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/spi_flash.html Esp32c3 has no image information at 0x0000 and contrary to the docu this information is at offset 0x0000
