i'm new to NXP. I want to try out the ble_thread_router_wireless_uart demo appilcation which i downloaded with the SDK i've builded using the MCUXpresso SDK Builder, name of the .zip-file:  NXP_SDK_2.2_FRDM-KW41Z. I executed the steps discribed in the "Kinetis Thread Stack Demo Applications User's Guide" PDF contained in the .zip-file to deploy the application with MCUXpresso IDE. When i'm building the example, i get the following output in the CDT Build Console:

I didn't change anything in the code or other files. Others with this problems hve posted their *.ld file in which the memory map is described, so here is mine:


/* Specify the memory areas */

TEXT_region1 (RX) : ORIGIN = m_text_start, LENGTH = (m_flash_config_start - m_text_start)
m_flash_config_region (RX) : ORIGIN = m_flash_config_start, LENGTH = (m_flash_config_end - m_flash_config_start)
TEXT_region2 (RX) : ORIGIN = m_flash_config_end + 1, LENGTH = (m_text_end - m_flash_config_end - 1)

DATA1_region (RW) : ORIGIN = m_data1_start, LENGTH = (m_data1_end - m_data1_start + 1)
DATA2_region (RW) : ORIGIN = m_data2_start, LENGTH = (__region_RAM2_end__ - __region_RAM2_start__ + 1)
PRODUCT_INFO_region (RX) : ORIGIN = m_fsl_prodInfo_start, LENGTH = (m_fsl_prodInfo_end - m_fsl_prodInfo_start)

I dind't change anything in the file, so the values used here are still default.


I'm using the FRDM-KW41Z Development Kit with the MCUXpresso IDE.


I'm thankfull for your answers.
