Unexpected boot to factory partition
Posted: Tue Jan 02, 2024 9:19 am
Hi,
We encounter an issue with our product built around an ESP32-WROOM-32-E.
Our setup is the following:
- factory partition with a kind of proprietary bootloader
- ota partition with the final application
- nvs partition including mandatory and optional settings for the final application
When all partitions are valid, we observe on undefined circumstances (electric perturbations ?), that sometimes the esp32 wrongly boots once from the factory partition. Then the product boots on ota partition again on next boot.
In our case this is very problematic as the factory application erases the nvs partition making the ota partition unusable.
Has anyone ever had this problem?
