Migrating sdk5 ANT Broadcast TX Example from nRF52832 to nRF52840

Question

Hi,

After successfully compiling and flashing both the blinky example and the ble_app_hrs on my nRF52840 I ran into an issue with ANT Broadcast TX example. The example is written for the nRF52832 so I changed the make file and the rom and ram in the linker file to what I thought were the appropriate values for the 52840. It compiled just fine but when I try to flash the S212 soft device and the application hex it does not like it. I am not sure what going wrong during flashing. I have tried changing the main.c to simplify it down to the blinky example but I am still unable to flash. I have attached my simplified main.c, my makefile, and my linker file.

I have a few hunches as to what might be wrong. 1) the linker file has the incorrect origin/length flash/ram values. 2) the softdevice is not being initialized by the application correctly 3) some other file such as the sdk_config.h needs to be changed to work with the 52840.

I appreciate any help with this. Thank you!
