ESP32C3 TRM - DIS_DIRECT_BOOT missing
Posted: Wed Jun 18, 2025 7:59 am
The current version of the technical reference manual for the ESP32C3 chip does not contain the eFuse DIS_DIRECT_BOOT. Instead, the same bit is described as 'EFUSE_RPT4_RESERVED8'. The according description is 'Reserved (used for four backups method). (RO)'
Anyway, the latest docu of the 'Security enablement workflow' for ESP32C3-Chips states, that it is strongly recommended to burn the 'DIS_DIRECT_BOOT' eFuse:
https://docs.espressif.com/projects/esp ... flows.html
Can someone clarify, which of the documents is wrong?
Best regards,
Markus
