Bootloader compatibility in ESP-IDF v5.0
Posted: Fri Jun 09, 2023 12:00 pm
HI,
I use ESP32S3-wroom-1 (N8R2) and current firmware is build with ESP-IDF v4.4.4.
We now plan to update to firmware build with ESP-IDF v5.0.
So, ESP32S3 works with v4.4.4 bootloder and v5.0 application.
In this case, esp_restart() does not work. It hangups in restart sequence.
And WDT and panic handler are also hangup and never startup without H/W reset.
On the other hand, v5.0 bootloader and v5.0 application combination works fine.
Following document says "bootloader supports newer versions of ESP-IDF".

Doesn't the v5.0 bootloader support v4 application?
thank you
