Yes thanks, the lines above sorted it. (I thought I clicked verify answer?)

Thanks! That's the missing piece that was eluding me.

Hello,

This error means '' '__device_dts_ord_130' undeclared here (not in a function);'' a missing kconfig or a device is referenced but not properly enabled in the device tree.

''Which as far as I can tell is spi00. If I enable spi00 then I get a conflict 'can only use one of spi00 twi00 uart00' etc'''

This means that flash driver is trying to use SPI0 which conflict with your UART0 as they both have same instances.

When you set SPI0 pin for internal flash, no other external flash or device should have the same SPI0 instance.

To use ZMS exclusively you can try to set the following config:

# Enable flash support (for internal flash)
CONFIG_FLASH=y

# Enable ZMS
CONFIG_ZMS=y

# Explicitly disable external flash drivers
CONFIG_SPI_NOR=n
CONFIG_NORDIC_QSPI_NOR=n
