Bus fault error when initiating connection on 2M/Coded PHY

Hi all,

I have two nRF52840-DK boards advertising on legacy(1M) and Coded PHY mode.

Connections on 1M PHY are working fine, however, for Coded or 2M, I am having a "Precise data bus error" on functions that I believe are part of S140 Soft Device library.

  • r14/lr: 0x00004f17 > ncs/v1.8.0/nrfxlib/softdevice_controller/lib/cortex-m4/hard-float/libsoftdevice_controller_multirole.a(libsoftdevice_controller_s140_debug_hardfp__obfuscated.elf)
  • Faulting instruction address (r15/pc): 0x00019e14 > ncs/v1.8.0/nrfxlib/softdevice_controller/lib/cortex-m4/hard-float/libsoftdevice_controller_multirole.a(libsoftdevice_controller_s140_debug_hardfp__obfuscated.elf)

I have tried to trigger the connection manually within scan_filter_match() callback function, but the result it is the same. Connections on1M PHY are opened successfully and Bus fault error on 2M/Coded PHY.

I am working with nRF Connect SDK v1.8.0 and SoftDevice HCI Controller.

Please find attached debug output screenshot and project folder.

Any suggestion would be much appreciated.

Kindest regards,
