samples: reduce k_malloc() heap size for ESP32 #281

Closed mniestroj closed 1 year ago

mniestroj commented 1 year ago

ESP32 platform has just 176.5 kB RAM for application use. This includes 128 kB reserved for RAM, which leaves just 48.5 kB for non-heap (k_malloc) use.

Reduce size of k_malloc() heap to 96 kB, which is what zephyr/samples/board/esp32/wifi_station uses. This increases non-heap RAM from 48.5 kB to 80.5 kB.

TODO:

[x] double check all samples

All samples tested. There is an issue with esp32 platform and DFU sample (does not confirm and reboot automatically), but not related to this PR. Merging.
