Linker issues in the connectivity firmware

RE: Linker issues in the connectivity firmware

Thank you for your help. I replaced the linker in ser_s132v5_hci and it worked. Also, is there any nordic documentation on the flash_placement.xml other than the video in the SES tutorial playlist provided by nordic

This is because you compiled ser_s132_hci, not ser_s132v5_hci as you said earlier. I did not test it with this project. You can move the section further up the file, to make it work with ser_s132_hci as well:

devzone.nordicsemi.com/.../5826.flash_5F00_placement.xml

I tried to build it using the flash_placement.xml you have provided but I got the following error

Other than using the flash_placement.xml you have provided, do I need to change any other of the build options?

Seems to be an issue in the flash_placement.xml file. The static placed section connectivity_version_info should be placed into the memory segment "FLASH" instead of in its own memory segment, to avoid that other code have already been placed in this section by the linker. I have attached updated flash_placement.xml file that can be used to successfully compile the project:

devzone.nordicsemi.com/.../flash_5F00_placement.xml

I installed SES 3.34 and got a fresh copy of the pc-ble-driver and SDK 15. Did the same steps as the first post to setup the SDK. I am still getting a linker error, but the segment it shows is different now but the location is same.

Ok, might be that Segger changed the location in SES 3.40. The settings looks correct, but could you try with SES v3.34, just to be sure? This is the version that the SDK have been tested with. You might need to make a fresh copy of the SDK and apply the patch one more time.

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

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
