Bootloader corrupted
Posted: Sun Mar 14, 2021 4:50 am
My ESP32 module reboots repeatedly with the error message below.
It was caused by accidental power down during the flashing of the new firmware.
Seems to me the bootloader was corrupted.
The standard procedure that pressing BOOT key after reset (where bootloader enters flash update mode) has no function now.
How I can recover the module? Please help.
Code: Select all
E (598) esp_image: Checksum failed. Calculated 0xcb read 0xe4
E (598) boot: Factory app partition is not bootable
E (599) boot: No bootable app partitions in the partition table
