STM32N6: flash partitions overlap #97850
Description
Describe the bug
The mcu-boot partition has a size of 256KB but the following slot0-partition already starts at offset partition@10000 - only 64KB.
Snippet from stm32n6570_dk_common.dtsi
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
/*
* Following flash partition is dedicated to the use of bootloader
*/
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x00000000 DT_SIZE_K(256)>;
};
slot0_partition: partition@10000 {
label = "image-0";
reg = <0x10000 DT_SIZE_K(1536)>;
};
slot1_partition: partition@210000 {
label = "image-1";
reg = <0x210000 DT_SIZE_K(1536)>;
};
storage_partition: partition@410000 {
label = "storage";
reg = <0x410000 DT_SIZE_K(64)>;
};
};
As soon as the bootloader exceeds 64KB in size, after flashing the STM DFU interface comes up instead of running mcu-boot.
