Saving core dump to flash on NRF54L15

[Maldus512]

Hello everyone,

I need to save a core dump on my NRF54L15 internal flash in order to debug an issue. I've been following the "Debugging and Troubleshooting section" of the intermediate academy course (https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-2-debugging/topic/build-errors-and-fatal-errors/).
Beside the fact that most configuration options listed as necessary are undefined an result in a failed build (see CONFIG_BOOT_DELAY_S, CONFIG_BOOT_DELAY_MS, CONFIG_BOOT_DELAY_SLEEPY_TICKS, CONFIG_BOOT_DELAY_SLEEPY_TIME and CONFIG_COREDUMP_FLASH_OFFSET), I cannot even enable the FLASH component.


Adding CONFIG_FLASH=y to my prj.conf causes an error because the symbol DT_N_S_soc_S_peripheral_50000000_S_vpr_4c000_IRQ_IDX_0_VAL_priority is undefined.
I am not sure of the reason behind it, but I did notice that instead of a flash0 node the nrf54l15 dts files list a cpuapp_rram node (see nrf54l15dk_nrf54l15_cpuapp.dts). Should I define the flash controller differently? What's exactly the difference between using cpuapp_rram and something like flash0? Does the NRF54L15 require a particular procedure to work with its internal storage?

Hello,

Please give the attached sample a try.

Hello,
Thank you for the assistance. The sample doesn't build, failing with the following error:

[Vidar Berg]

Please let me know which SDK version you are on. From the release notes linked above you can see this setting was introduced in SDK v3.1.0

[Maldus512]

V3.0.0

[Vidar Berg]

OK, please upgrade to v3.1.1 if possible so you can use the new coredump NV backend mentioned in this relase notes. If using the other flash backend you need to have CONFIG_ASSERT disabled since the RRAM drivers are not meant to run in an interrupt context.

[Maldus512]

I upgraded to v3.1.1. The course I linked however displays a version range between 2.7.0 and 3.1.0, is it a documentation issue?

With the new version your example compiles but my own project still doesn't. It complains about a missing node that I cannot recognize:

I have setup a similar DTS tree, with a coredump_partition in cpuapp_rram:

&cpuapp_rram {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;
		boot_partition: partition@0 {
			label = "mcuboot";
			reg = <0x0 DT_SIZE_K(64)>;
		};
		slot0_partition: partition@10000 {
			label = "image-0";
			reg = <0x10000 DT_SIZE_K(324)>;
		};
		slot1_partition: partition@61000 {
			label = "image-1";
			reg = <0x61000 DT_SIZE_K(324)>;
		};
                coredump_partition: partition@b2000 {
                        label = "coredump-partition";
                        reg = <0xb2000 DT_SIZE_K(4)>;
                };
	};
};

The errors are related to the sQSPI peripheral which is not used by coredump, but it means you can free up the 64K of RAM allocated to FLPR as I did in my test sample.

I upgraded to v3.1.1. The course I linked however displays a version range between 2.7.0 and 3.1.0, is it a documentation issue?

SDK v3.1.0 introduced a new backend for coredump that is better suited for handling NV storage in the fault handler, but the course has not been updated to reflect this change yet, so it is still suggesting the old backend which does still work if you dont have CONFIG_ASSSERT enabled.

The configurations below are wrong and should not be used. Not sure when they got added there. I will report it internally.
