Esp32S3 : How to access Read/Write flash partition from bootloader hook
Posted: Fri Jan 19, 2024 1:58 pm
Good afternoon,
Using the Esp32S3 chip, I managed to define a "bootloader_component"
"bootloader_components/my_boot_hooks/hooks.c"
where a placed a void bootloader_before_init(void) {}
definition.
From that function, I would like to read and write some bytes of a flash partition.
Do you know how to do it ?
Which are the functions that I can call ?=from this point ??
Thank you for your help,
Thomas TRUILHE
