Sig block 0 signed with untrusted key on ESP32
Posted: Mon Nov 20, 2023 2:57 am
Hi All,
My device is ESP32-WROVER-E with branch release/v5.1 from GitHub.
I try to enable sign and encrypt like this.
I already enable ABS_DONE_1 and write Security boot key, please check attachment.
This is my partition table.
I try to use following commands to flash my device.
When I try to run "hello world" example code, I will have following output.
Anyone can help or teach which part is wrong? I would like to try sign and encrypt at ESP32 to see my understanding for whole secure boot. Thanks.
