Bootloader Configuration to load image

Postby aygh4266 » Tue May 28, 2024 8:37 am

hello everyone,

I am new in ESP32 world and I wonder if it is possible to load the image from a FAT partition. If not, So how can I configure the bootloader to load the image from ota_0 app partition.

Thanks in advance

It's not possible. The bootloader needs the image to be aligned to the MMU page size in order to succesfully map it, and the alignment of a file on a FAT partition depends on how the host writes it; it's unlikely to be aligned correctly.
