Linker issues in the connectivity firmware

[TS Gowtham]

Hi,

I am trying to build the connectivity firmware for a custom dongle based on the nrf52832. I am getting a section overlap issue when I am trying to build the solution from SES.

Steps followed til now:

-> Downloaded the latest version of pc-ble-driver from the github page.

-> Ran the bootstrap_sd_api_v5 script.

-> Opened the ble_connectivity_s132v5_hci_pca10040 located at pc-ble-driver-master\sdk\nRF5_SDK_15.0.0_a53641a\examples\connectivity\ble_connectivity\pca10040\ser_s132v5_hci\ses\

-> Tried to build the solution but got the following error

1> Linking ble_connectivity_s132v5_hci_pca10040.elf

Hi,

Can you check that sdk150_add_sd_v3v5_support.patch:84195 have been applied to the SES project setting. 

• Project 'ble_connectivity_s132_hci_pca10040' Options
• Common configuration
• Linker->Section Placement Segments
• Check that "connectivity_version_info RX 0x30000 0x18" is included

Best regards,
Jørgen

Under Linker, I can't find any Section Placement Segments. There are 'Section Placement Macros' and 'Section Placement File'. There was an option under build, 'Memory Segments', which has the line you spoke of.

Contents of Build->Memory Segments

FLASH RX 0x0 0x80000
RAM RWX 0x20000000 0x10000
connectivity_version_info RX 0x30000 0x18

Contents of Linker->Section Placement Macros

FLASH_PH_START=0x0
FLASH_PH_SIZE=0x80000
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x10000
FLASH_START=0x26000
FLASH_SIZE=0x5a000
RAM_START=0x2000b8a8
RAM_SIZE=0x4758

These are all under 'Common' configuration.

Which one should I edit?

Thank you
