Re: Custom partition for storing data
Thanks Neil,
I have now created a customized partition.
I would also like to know that each location in esp32 flash is of how much bytes. eg. if I am using
spi_flash_write(0x304240 temp, sizeof(temp));
then 0x304240 can store how much bytes?

Hello,
You can also enable "compressed upload" in "serial flasher config" in "menuconfig" utility.
