Memory map difference SES vs ARMGCC

[tni]

I am testing nRF5_SDK_17.1 examples/dfu/secure_bootloader/pca10040_uart_debug

After I run on SES. I got this memory map. It overlaps softdevice area.

With armgcc, after make & make flash, I got this memory map

As my understanding, memory map should be same with SES and ARMGCC.

Do you know why memory map layout is so different?

I guess SES does not refer .ld file.

Thanks,

Hi,

Did you remember to flash the softdevice with make flash_softdevice? Make flash command only flashes the application, while SES does this auto when you build and flash your application.

I found I need to flash SoftDevice.

SES does not flash SoftDevcie automatically.

SES also does not refer .id file for staring address. SES pickup lowest address.

Thanks,
