Hello,
as stated in the Titel im trying to read Firmware Information, for Example the Firmware Version.
I tried solving this by reading via Flashareas but no matter where i try to read the Flash is apparently completely empty (reading only 0xFF Bytes).
There seem to be no errors while reading.
My Questions are, is there a better way to do this and if not where can i find out where the Image Data is located at ?
The Programm i use for testing is this flash_reader.rar
My Project Config is this:
CONFIG_HEAP_MEM_POOL_SIZE=2048 CONFIG_MAIN_STACK_SIZE=8192 CONFIG_FLASH=y CONFIG_IMG_MANAGER=y CONFIG_IMG_ERASE_PROGRESSIVELY=y CONFIG_MPU_ALLOW_FLASH_WRITE=y
+ Logging Config Commands
and this is the Flash Layout i use(its the default devicetree one for the NRF52840)
&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 0x0001e000>;
};
storage_partition: partition@f8000 {
label = "storage";
reg = <0x000f8000 0x00008000>;
};
};
};I checked to see if there is information at 0xC000 and 0x73000 but all i read is 0xFF
Any possible Solutions or Ideas would be greatly appreceated
Regards,
Nick
