I am using the new WROVER-E and trying my luck with the secure boot V2.
I am having an issue with updating the ota partition with a new image.
At the end, the esp_ota_end() is called, this causes the system to reboot without any message.
Tracked it down to esp_secure_boot_verify_rsa_signature_block():
Its failing in a call to a ROM function in this part of the code:
Code: Select all
int r = ets_secure_boot_read_key_digests(&trusted_keys);
if (r != 0) {
ESP_LOGE(TAG, "No trusted key digests were found in efuse!");
} else {
ESP_LOGD(TAG, "Verifying with RSA-PSS...");
// TODO: calling this function in IDF app context is unsafe
r = ets_secure_boot_verify_signature(sig_block, image_digest, &trusted_keys, verified_digest);
}
Any help on this would be appreciated, because we need to ship our product in about two weeks and i would be unhappy if we need to use the V1...
Thanks,
Simon
