- When NVS encryption is enabled on SoCs with the HMAC peripheral that have flash encryption
enabled, the HMAC-based NVS encryption scheme is now selected as default instead of the
flash encryption-based scheme.
- If your application previously used the flash encryption-based scheme, you need to manually
configure the NVS encryption scheme to flash encryption from HMAC through ``menuconfig``
or your project's ``sdkconfig`` (i.e., setting ``CONFIG_NVS_SEC_KEY_PROTECT_USING_FLASH_ENC=y``).
The issue is `esp_flash_write_encryped` function in ROM on ESP32C3, ESP32S3
calls legacy implementation, which uses old configuration. And this causes
write fails.
The solution in this commit is to compile and link this function(and related)
in IRAM instead of the ROM one.
The IRAM cost increases around 1.2KB after the fix
