Hi,

The use of the area from 2Mbyte up is not compatible with the use of devices build by Sonoff which are probably our biggest target for real life deployment. Personally I would use 0x7A000 as being compatible with such devices and allowing FOTA strategies

I’m not an expert in memory layout, this address seem to work for me. But! As with any flash library it can be configured with preprocessor defines in Makefile:

EXTRA_CFLAGS += -DSPIFLASH_BASE_ADDR=0x7A000

Also had trouble with this, setting it via EXTRA_CFLAGS didn't seem to work for me, had to go and manually set it in component.mkL15: HOMEKIT_SPI_FLASH_BASE_ADDR ?= 0x70000.

(Using this with an ESP-01)

Ok, for the record so that people who will read it later won't get wrong information: to use example on ESP-01, you need to set FLASH_SIZE variable to 8 and HOMEKIT_SPI_FLASH_BASE_ADDR to 0x7a000 (and of course latest version of the code):

make -C examples/led FLASH_SIZE=8 HOMEKIT_SPI_FLASH_BASE_ADDR=0x7a000 all

or through environment variables:

export FLASH_SIZE=8
export HOMEKIT_SPI_FLASH_BASE_ADDR=0x7a000
make -C examples/led all
