Whats the largest firmware binary you've seen?
Posted: Wed Feb 08, 2023 3:37 am
My firmware with a couple third-party components is 1.82MB. Has anyone seen significantly larger?
A 4MB ESP32 has too little margin for my comfort once I add NVS and a small SPIFFS area, so I'm running a 16MB part. I currently have 3.01MB per OTA partition and am curious if anyone's firmware binary is threatening to overflow even this?
(...plus some reserved areas defined after this of varying sizes, to take it up to 16MB, in case a future OTA update has need for another storage area)
