I want to use mcuboot together with LittleFS/NVS and a custom partition foo with my own flash storage routines. It works as long CONFIG_BOOTLOADER_MCUBOOT=n.
But with CONFIG_BOOTLOADER_MCUBOOT=y it does not recognise the foo partition. In contrast, it does with the usual partitions like storage
#if DT_HAS_FIXED_PARTITION_LABEL(foo) #define FLASH_TEST_ID DT_FIXED_PARTITION_ID(foo) #define FLASH_TEST_OFFSET FLASH_AREA_OFFSET(FLASH_TEST_ID) #define FLASH_TEST_SIZE FLASH_AREA_SIZE(FLASH_TEST_ID) #else #error "foo" partition is not defined #endif
In devicetree_unfixed.h there is no difference between foo and storage. In the pm_config.h the are only entries for storage but none for foo. That seems to be the root of the problem.
#define PM_LITTLEFS_STORAGE_OFFSET 0xfa000 #define PM_LITTLEFS_STORAGE_ADDRESS 0xfa000 #define PM_LITTLEFS_STORAGE_END_ADDRESS 0x100000 #define PM_LITTLEFS_STORAGE_SIZE 0x6000 #define PM_LITTLEFS_STORAGE_NAME littlefs_storage #define PM_LITTLEFS_STORAGE_ID 7 #define PM_littlefs_storage_ID PM_LITTLEFS_STORAGE_ID #define PM_littlefs_storage_IS_ENABLED 1
In the dts is following definition
&flash0 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x000000000 0x0000C000>;
};
slot0_partition: partition@c000 {
label = "image-0";
reg = <0x0000C000 0x00067000>;
};
slot1_partition: partition@73000 {
label = "image-1";
reg = <0x00073000 0x00067000>;
};
scratch_partition: partition@da000 {
label = "image-scratch";
reg = <0x000da000 0x0001c000>;
};
/*
* Foo partion to experiment with dedicated storage
*/
foo_partition: partition@ea000 {
label = "foo";
reg = <0x000ea000 0x00002000>;
};
/*
* Storage partition will be used by FCB/LittleFS/NVS
* if enabled.
*/
storage_partition: partition@85000 {
label = "storage";
reg = <0x00085000 0x00008000>;
};
};
};
What can I configure to get the foo partition to pm_config.h?
Do I have to use pm_static.yml even with the partitions defined in the dts file? I do not use pm_static.yml yet.
