ESP32-C3: “Image requires efuse blk rev >= v419.62, but chip is v1.2” with cargo-espflash 4.0-dev (4006bd0) #870
Description
Describe the problem
When flashing my firmware to an ESP32-C3 using cargo-espflash 4.0-dev (commit 4006bd0), the device fails to boot, and the log shows the following error:

I’m not sure if I might be missing a required setting or configuration to support this chip revision, or if this could be related to how espflash generates or flashes the image.
If you have any suggestions or workarounds, I would greatly appreciate your guidance.
