ESP32 Forum

Hi,
Currently I am working Esp wroom32 ,right now i want to know whether i can modify Ota slots size in partition table,if so what is the minimum size i can provide to perform OTA. In the Programming guide they mentioned 1MB for each OTA slots.

It depends on your .bin file size. You can check the size of your program by checking the "MyProject.bin" file in your build folder. Running "make size" also works.

If say your total image size is smaller than 1mb you can shrink it by specifying a custom partition table in "make menuconfig"
