== Flashing the Bootloader ==
If you get this error in console, Likely bootloader is corrupt or erased:
invalid header: 0xffffffff
Download new bootloader file from this Zip file:
https://docs.espressif.com/projects/esp-at/en/release-v2.4.0.0/esp32c3/AT_Binary_Lists/ESP32-C3_AT_binaries.html
Install the bootloader at 0x0 location:
esptool.py --port /dev/ttyACM0 --baud 9600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_size detect 0x0 bootloader.bin
* If you get this error while installing both bootloader & the Application files:
Detected overlap at address: 0x8000 for file:
You need to give proper space between the files:
0x1000 bootloader.bin 0x8000 esp32-idf4-20191220-v1.12.bin
* If you see these error in Console:
E (540) esp_image: Image length 1339808 doesn't fit in partition length 1114112
;31mE (541) boot: Factory app partition is not bootable
E (543) boot: No bootable app partitions in the partition table
Or:
E (54) flash_parts: partition 0 invalid magic number 0x6e9
E (60) boot: Failed to verify partition table
E (65) boot: load partition table error!
Most likely the Bootloader is installed but there is no application installed or is not bootable.
