Our HomeKit experts responds with:

In HomeKit sample in prj.configs there are:

### External flash Cconfiguration for secondary app image slot
CONFIG_NORDIC_QSPI_NOR=y
CONFIG_NORDIC_QSPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096
CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE=16
 
CONFIG_PM_EXTERNAL_FLASH=y
CONFIG_PM_EXTERNAL_FLASH_DEV_NAME="MX25R64"
CONFIG_PM_EXTERNAL_FLASH_BASE=0x0
CONFIG_PM_EXTERNAL_FLASH_SIZE=0x800000

and in homekit/samples/multiprotocol/child_image/mcuboot.conf

### External flash
CONFIG_NORDIC_QSPI_NOR=y
CONFIG_NORDIC_QSPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096
CONFIG_NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE=16

Let me know how this works for you. 

Kind regards,
Øyvind

Yes, It can work, if I use the nrf52840-dk, but my problem is my product use the other qspi flash, It's not MAX25R64. I want to use P25Q80H. and I want to know how to support P25Q80H qspi flash
