Problem Description

Hello, I have a problem with the flash encryption feature in my project. I have followed the steps that appear in the example esp-idf/examples/security/flash_encryption but when the program executes the function “esp_partition_write”, the task hangs and does not continue. Furthermore any exception appears, only appears logs coming from task wdt because the task is hanged.

The data length that I am trying to write is multiple of 16 (128 bytes) with a offset 0. The partition is marked with the “encrypted” flag in the partition table.

If I remove the “encrypted” flag, the process runs correctly

Other items if possible

• sdkconfig file (attach the sdkconfig file from your project folder)
• Partitions table
• elf file in the build folder (note this may contain all the code details and symbols of your project.)
• coredump (This provides stacks of tasks.)
