After having migraded IDF from 4.4 to 5.0.1, I have got new warning messages when ESP32-S3-DevKitC boots up and before my own application code starts.
(1) spi_flash: Detected size(8192k) larger than the size in the binary image header(2048k). Using the size in the binary image header
(2) eFuse: calibration efuse version does not match, set default version: 0
Can anyone help me to understand what these two warning messages mean? and how should I fix them?
I could not find any useful infomation from the internet. FYI, I am using ADC in my project. Below I have copied the complete message log.
Thanks!
