Still running into this on 53139c293ba77c457484f8f08ae94b4323d0228f, also tried setting the spi_flash size and that didn't work

I have this issue as well, I think its because of the default partition tables/bootloader, if I flash the blufi example project from esp-idf repo then flash a legacy image of esphome onto the 0x10000 address, it will boot fine but OTAs wont work obviously

Hi,

I have the same ESP-C3-32S (2Mb Variant) board and issue. I managed to boot the board with ESPHome using this information: https://community.home-assistant.io/t/esp32-c3-boot-loop-2mb-flash/466311

The reason behing the issue is the size of the binary file which doesn't fit in the 2MB of external flash. I'm not sure that solves the actual issue but it gives some workaround to play with ESPHome on these boards.
