Cannot perform OTA, not enough space on WROOM 32D 16 Mb

[brahmajit]

I've a code that is already running on the device and want to perform OTA. But I cannot initiate the OTA, it shows "not enough space to begin OTA". My code is little bit big with 4 freertos tasks running and is around 1.4 Mb when compiled as a binary. I don't know what is happening there enough space for the app and OTA (16 Mb, 3 Mb App and 9 Mb FATFS or 2 Mb App and 12.5 Mb FAT).

Before uploading the Original Sketch you must choose a Partition scheme which provides enough space for subsequent OTA operation. Maybe you have set a partition scheme without OTA support or with too less OTA partition.
