Web it seems that 16mb flash and 8mb psram can be mapped from, but the windows are 4mb or about 3.2mb for instruction access. Web so far, with wifi connection function, it worked well and available update ota via websocket. 5) when the “ erasing ” process begins, you can release the “. Is it true that the flash memory of the esp32 can slowly break after about 100000 write cycles? Up to 10.5mb of address space can be used to access the external flash or spiram.
First 32kb iram is used as a cpu0 cache and next 32kb is used as cpu1 cache memory. For today’s tutorial, we will learn how to read and write data to the esp32’s flash memory. 11.5mb should be able to map into instruction address space on 32 bit alignment, but i could not read back correct values using mmap and could not find reported success using registers so i mmap in chunks to data. For today’s tutorial, we will learn how to read and write data to the esp32’s flash memory.
