ESP 32 logs

Hello, actually i'm using esp8266 but for some reason mine is a bite bugged, some times stop from working, idk why. So i'm migrating to esp32, uploaded the firmware fine, but the size for register logs is too much reduced, like its 568,000 bytes available, is that right? And another question, i'm gona start using iSpindel, i need to start log register to use with them?
