Linker script for OpenThread

[LRA_]

Hello,

I am trying to adapt open thread coap example to use with the PCA10059/NRF52840 Dongle board. I am using segger IDE.

I adapted the CLI to use the USB like in the thread_cli_usb_bootloader example. Still, the code was getting stuck in "otInstanceInitSingle". I saw this thread about using multiprocol  and I guessed it was something similar. Unfortunately I did not find the best way to solve this.

I could not find any way to change the linker file, maybe I did it correctly and am unaware. 
When I checked "flash_placement.xml" in the thread_cli_usb_bootloader example and compared to the coap and found a difference. I just tried to replace it and the example ran fine.
Is there a correct way to do this?

Hi.

The "linker file" in Segger Embedded Studio is the "Section Flash Placement", you can see here how you can change them.

Best regards,

Hello, thanks for the answer.

Well I already had changed the "section placement macros".
When searching for "flash" in the options it showed "memory segments" under build. It seems that's the thing I was looking for, where it has on the PCA10059 project "ot_flash_data RX 0x000dc000 0x4000" and in the PCA10056 project "ot_flash_data RX 0x000fc000 0x4000".

Is there any reason this has to be different depending on the board?

Which example are you looking at when you find this?

Which file, is it flash_placement.xml?

[LRA_]

thread_cli_usb_bootloader for the PC10059.
Any other thread example for the PC10056.

I was looking at the options of the project. flash_placement.xml does reflect the values that are in the options.

Hi.

It is probably 0xDC000 in order to make room for the bootloader.

Best regards,
