Dear Eugene Yu.

Thank you very much for your help. I just redefine memory map, it works very well.

Hello Mr.Kwak,

Each of Softdevices has different size.

So you need to look into the release note for specific version of Softdevice.

For example, the your current version (s140 v6.1.0) of release note has as below.

---------------------------------------------------------------------------------------

SoftDevice Properties

This SoftDevice is production tested for nRF52840.
This SoftDevice contains the Master Boot Record (MBR) version 2.3.0 (DRGN-9755).
The combined MBR and SoftDevice memory requirements for this version are the same as for the s140_nrf52_6.0.0:
- Flash: 152 kB (0x26000 bytes).
- RAM: 5.54 kB (0x1628 bytes). This is the minimum required memory. The actual requirements depend on the configuration
- chosen at sd_ble_enable() time.
The Firmware ID of this SoftDevice is 0x00AE.

---------------------------------------------------------------------------------------

Try to configure linker's memory map to

IROM1 : 0x26000 0xD4000

Thanks,

Eugene

Dear Vidar Berg. Thank you very much for your help. But I don't know how to change the linker configuration. Could you please let me know how to change?

I actually changed memory map as below.

But it still makes same error.

I hope your reply.

Hi,

The DTM examples starts at address 0x0 in flash which overlaps with the softdevice, hence the error. So you need to change the linker configuration for the example so it starts above the softdevice if you want to merge both.
