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

Thank you

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?

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:

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
