It does has to do with flash address.
0x40000 means the code be programmed at flash address 0x40000
0x10000 then the AT firmwares programmed at flash address 0x10000.

0x10000 then the AT firmwares programmed at flash address 0x10000.

Where did you took the 0x40000 number ? Is the firmware you wish to use has been built according to that address ?
BTW, also, don't expect having both custom firmware and AT firmware running at the same time.
