nrf52811 FreeRTOS porting Linker RAM definition

[VadymS]

Hi.  I want to use nrf52811 with FreeRTOS with SDK 16.0. I have trouble with configure RAM_start in a linker file.

I tried to use the value 0x20001ae0 from "ble_app_blinky" project for emulated PCA10056e_S112" and it doesn't work.

I compared the HRS examples with and without FreeRTOS for the same nrf52840 with same SD s140 . 
For HRS without FreeRTOS i see           " define symbol __ICFEDIT_region_RAM_start__   = 0x20002be0; "
For HRS with FreeRTOS                         "define symbol __ICFEDIT_region_RAM_start__   = 0x20005968; "

Does the value of the RAM depend not only from SoftDevice? And how can I calculate it?

Hi Vadym

What IDE are you using? If you're using SEGGER Embedded Studios (SES) you should get an error when building the application stating what the RAM and flash should be set to if these values are set too low. You can also use our adjustment of RAM and Flash memory guide to see what the minimum set RAM and flash addresses for each of the SoftDevice versions are, and how you can set these in the various IDEs.

Best regards,

Simon
