Memory mapping with segger and zephyr

[titi17]

Hello,

I can't set the memory map into segger with a zephyr project.

For example for blinky project into ncs/zephyr/samples/blinky.

When I go to Project->Options, I don't have Linker options (see my screenshot).

I'm using Segger embedded studio for ARM (Nordic Edition) V4.30c with nrf52832.

I've seen this but it doesn't help me : https://wiki.segger.com/Add_new_Memory_Sections_and_Segments

Thanks

Hi.

Why do you want to change the memory map?

In NCS, most configuration is done through Kconfig or device trees, not compiler flags (or, flags are set based on Kconfig and device trees).

You can find more information here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/dts/index.html#flash-partitions

Best regards,

Didrik

I want to change memory map to have the capabilities to set multiple program on my device (to update program for example).

I change my DTS file "nrf52_pca10040.dts" and I shift the location to start at 0x1000 of the partition and it doesn't work. Zephyr.dts is modified on the build but in debugger when i see the memory, there is always data between 0x0000 and 0x1000.

boot_partition: partition@1000 {
            label = "mcuboot";
            reg = <0x00001000 0xb000>;
        };

Regards.

My bad, it works :-)
