<![CDATA[Core OTA issues]]>I have M5 Core, which I understand to have 4MB flash.

My firmware.bin is 1,065,552 bytes.

It seems like after the OTA update after reboot, the old firmware still loads, and then I get an error that there's no room to OTA.

Same code works fine on other ESP32 dev boards.

Any ideas? Is something interfering with the self-reflashing?

EDIT:

In platformio I see the following when I build:

Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"
RAM: [= ] 13.9% (used 45448 bytes from 327680 bytes)
Flash: [======== ] 81.3% (used 1065286 bytes from 1310720 bytes)

Why does it seem like I don't really have 4MB of flash, or that so much is being reserved for RAM?

It refers to the wireless delivery of new or updated software or firmware to devices such as smartphones and tablets.
