Hello! My starting point for this issue is a custom board using an nrf52832 and a SPI flash chip (MX25R1635F).
So far I have been able to initialize the SPI flash (the JEDEC ID is read and verified successfully), but I want to use it with the FCB system (currently working fine on internal flash).
I followed the instructions here (or at least I tried to) to set up a partition in external flash that I can then reference when initializing the FCB. When I build, I'm getting hundreds of lines of errors, most along these lines:
error: unknown type name 'NRF_QSPI_Type'; did you mean 'NRF_SPI_Type'?
967 | NRF_STATIC_INLINE void nrf_qspi_cinstr_long_transfer_start(NRF_QSPI_Type * p_reg,
| ^~~~~~~~~~~~~
| NRF_SPI_Type
Along with
zephyr/drivers/flash/nrf_qspi_nor.c:69:2: error: #error "No size specified. 'size' or 'size-in-bytes' must be set" 69 | #error "No size specified. 'size' or 'size-in-bytes' must be set"
This led me to try setting `CONFIG_NORDIC_QSPI_NOR=n` explicitly in my proj.conf, but it's still showing the same errors (even with PM_OVERRIDE_EXTERNAL_DRIVER_CHECK). When I look in the .config file in the build folder (snippet below), it's getting set back to `y`, but I can't find any clue as to why.
# # Nordic nRF Connect # CONFIG_BOOT_BANNER_STRING="Booting nRF Connect SDK" CONFIG_MBEDTLS_LIBRARY_NRF_SECURITY=y CONFIG_WARN_EXPERIMENTAL=y CONFIG_PRIVILEGED_STACK_SIZE=1024 CONFIG_MCUMGR_TRANSPORT_NETBUF_SIZE=2475 CONFIG_BT_BUF_CMD_TX_COUNT=2 CONFIG_ENTROPY_GENERATOR=y CONFIG_INIT_ARCH_HW_AT_BOOT=y CONFIG_NORDIC_QSPI_NOR=y CONFIG_NORDIC_QSPI_NOR_FLASH_LAYOUT_PAGE_SIZE=4096 # CONFIG_GETOPT is not set # CONFIG_NCS_SAMPLES_DEFAULTS is not set
Here are the rest of the relevant config snippets:
The flash device is configured in my overlay as below

nordic,pm-ext-flash = &mx25r1635;
};

};

};
};
/* other configs */

};
};
I have the following pm_static.yml
nvs_storage: address: 0x7B000 end_address: 0x7D000 region: flash_primary size: 0x2000 internal_fcb: address: 0x7D000 end_address: 0x80000 region: flash_primary size: 0x3000 external_fcb: address: 0x000000 device: MX25R16 end_address: 0x1000000 region: external_flash size: 0x1000000
The following is a snippet from my prj.conf
# Internal Flash/NVS CONFIG_MPU_ALLOW_FLASH_WRITE=y CONFIG_FLASH=y CONFIG_IMG_MANAGER=y CONFIG_STREAM_FLASH=y CONFIG_FLASH_MAP=y CONFIG_FLASH_PAGE_LAYOUT=y CONFIG_NVS=y CONFIG_MPU=y CONFIG_SOC_FLASH_NRF_UICR=y CONFIG_SOC_FLASH_NRF_EMULATE_ONE_BYTE_WRITE_ACCESS=y # SPI Flash CONFIG_SPI=y # CONFIG_SOC_NRF52832_ALLOW_SPIM_DESPITE_PAN_58=y CONFIG_SPI_NOR=y CONFIG_NORDIC_QSPI_NOR=n CONFIG_PPI_TRACE=y CONFIG_FCB=y CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y
A handful of items in there were gleaned from various support tickets, but many of them may have been out of date. Anyway, I appreciate any guidance you can provide.
Thank you!
