Hello,

According to the AN5185:

  • If SBRV Option Bytes value is 0x3D800 (for FUS V0.5.3) or 0x3D000 (for FUS V1.x.z) then FUS must be running
  • If SBRV Option Bytes value is different from 0x3D800 (for FUS V0.5.3) and from 0x3D000 (for FUS V1.x.z) then FUS is not running

Best Regards

And in that case the SBRRV option byte should be pointing at the start of the wireless stack, which, in case of a successful installation at 0x080CE000, should be 0x33800
