In ESP document for flash encryption i found

OTA updates to encrypted partitions will automatically write encrypted, as long as the esp_partition_write function is used.

And in

Code: Select all

esp_ota_write

we use

Code: Select all

esp_partition_write

It mean the firmware ota is must be plaintext firmware.
But i want to do ota with encrypted firmware. This is a requirement for production.
Based on IDF document, i think i have to modified

Code: Select all

esp_partition_write

for write unencrypted data.

Is there any solution for this?
I also looking for ESP32 production guide.
