Re: Fatal error ESP32S2 after Secure Boot Experiments
Hi stan-k I see. Since Secure Boot is a security feature on which the root of trust depends completely, hence it is not possible to disable secure boot once it is enabled for the device. After you have disabled the ROM DL mode then the espefuse script would not work with the chip. So no more eFuse r...

Re: Fatal error ESP32S2 after Secure Boot Experiments
Hi stan-k,
As Nespressif has suggested, are you able to obtain the eFuse summary, can you share it with us?
I am sharing a link to a similar issue faced on esp32 https://github.com/espressif/esptool/issues/741 Can you see if the steps given there help your use-case?
Thanks,
Aditya

Re: Eror in esp-cryptoauthlib atecc608b
Hi oedzee, It looks like this issue is related to the Serial Port. The script esp_cryptoauth_utility internally uses esptool. Below are some requirements for serial connection with esptool related to Serial Port. https://docs.espressif.com/projects/esptool/en/latest/esp32/esptool/basic-options.html#...

Re: Flash encryption with micropython and reflashing
Hi MauroDiam, I'm not using the reflashing option (see here) of the Flash encryption Development mode, bacause the efuse FLASH_CRYPT_CNT has just 7 bits so the board could be reflashed just 4 times, is it correct? Please note that the 7 bits are not related to the flashing. Those 7 bits indicate the...

Is it a good practice only or is there a technical reason ? What append / what is the risk if the signer certific...

Re: OTA update using DS module
Hi Alex,
Yes you are right, the DS support is not present in the client configuration structure.
I will soon share a patch with you that shall enable you to use DS peripheral for establishing the TLS connection at the time of OTA.
