Hello I have an nRF52840 board with a 2 MB external flash
I'm using SDK 2.6.2
I'd like to configure the mcuboot_secondary partition to be on the external flash
Here is my pm_static.yml
# Internal flash partitions
mcuboot:
address: 0x00000000
size: 0x0000C000 # 48 KB
settings_storage:
address: 0x000F8000
size: 0x00007800 # 30 KB
app_config:
address: 0x000FF800
size: 0x00000800 # 2 KB
# External flash region
external_flash:
address: 0x00000000
size: 0x00200000 # 2 MB
end_address: 0x00200000
region: external_flash
# External flash partitions
mcuboot_secondary:
address: 0x00000000
size: 0x00100000 # 1 MB
region: external_flash
device: QSPI_FLASH
end_address: 0x00100000
scratch_partition:
address: 0x00100000
size: 0x00010000 # 64 KB
region: external_flash
device: QSPI_FLASH
end_address: 0x00110000
qspi_app_storage:
address: 0x00110000
size: 0x000F0000 # 960 KB
region: external_flash
device: QSPI_FLASH
end_address: 0x00200000
DTS file:
chosen {
.....
pm_ext_flash = &qspi_flash0;
};
&qspi {
status = "okay";
pinctrl-0 = <&qspi_default>;
pinctrl-1 = <&qspi_sleep>;
pinctrl-names = "default", "sleep";
qspi_flash0: qspi_flash@0 {
compatible = "nordic,qspi-nor";
status = "okay";
label = "QSPI_FLASH";
reg = <0>;
sck-frequency = <16000000>;
writeoc = "pp4o"; /* enable quad page program */
readoc = "read4io"; /* enable quad fast read */
jedec-id = [c8 40 15];
size = <0x00200000>; /* 2 MiB */
has-dpd;
t-enter-dpd = <20000>; /* match datasheet typical */
t-exit-dpd = <20000>;
quad-enable-requirements = "S2B1v1"; /* required for quad mode */
partitions {
status = "okay";
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
mcuboot_secondary: partition@0 {
label = "mcuboot_secondary";
reg = <0x000000 0x100000>; /* 1MB */
};
scratch_partition: partition@100000 {
label = "scratch";
reg = <0x100000 0x10000>; /* 64KB */
};
qspi_storage: partition@110000 {
label = "qspi_storage";
reg = <0x110000 0xF0000>; /* 960KB */
};
};
};
};
BUT I'm still getting compile error:
C:/ncs/v2.6.2/bootloader/mcuboot/boot/zephyr/include/sysflash/pm_sysflash.h: In function '__flash_area_ids_for_slot':
C:/ncs/v2.6.2/bootloader/mcuboot/boot/zephyr/include/sysflash/pm_sysflash.h:47:60: error: 'PM_MCUBOOT_SECONDARY_ID' undeclared (first use in this function); did you mean 'PM_MCUBOOT_PRIMARY_ID'?
47 | #define FLASH_AREA_IMAGE_0_SLOTS PM_MCUBOOT_PRIMARY_ID, PM_MCUBOOT_SECONDARY_ID
| ^~~~~~~~~~~~~~~~~~~~~~~
SDK is 2.6.2
When I examine the partitions.yml in and pm_config there is no mention of the mcuboot secondary. Looks like my pm_static.yml is ignored even though I see this message in the build log
Found partition manager static configuration:..../pm_static.yml
Partition 'mcuboot' is not included in the dynamic resolving since it is statically defined.
Partition 'settings_storage' is not included in the dynamic resolving since it is statically defined.
Partition 'mcuboot_secondary' is not included in the dynamic resolving since it is statically defined.

Any ideas?
Thank you
