S120 softdevice 32K RAM support on xxac devices

Hello, from looking at the GCC linker files I take it that S120 softdevice doesn't support using the full 32KB RAM of the new nrf51422-xxac devices. Is this something that will require a new version of the softdevice or can it be achieved by changing the linker scripts?

S120 v2.0.0 works with the XXAC devices and 32 KiBy RAM. It's just the v1.0.1 ones that blow chunks in that situation.

I seem to have totally missed that post. I managed to get it to work after fiddling with it for a while. For anyone else having trouble, I had to make following changes:

• used SDK version 7.2.0 and S120 version 2.0.0
• used S120 version 2.0.0 header files
• flash origin=0x1d000, length=0x23000
• in device_manager_central.c added missing parameter in sd_ble_gatts_sys_attr_get and _set calls
• in application added sd_ble_enable call after softdevice init
