nrf52840pdk split image doesnt successfully write second image

[jacobrosenthal]

Has anyone run a split on an nrf52840pdk lately? Neither of my boards are showing the second image.... Current upstream newt tool, newtmgr, and core

Bog standard target

Jacobs-MacBook-Air:chippd3 jacobrosenthal$ newt target show split-default
targets/split-default
   app=@apache-mynewt-core/apps/blesplit
   bsp=@apache-mynewt-core/hw/bsp/nrf52840pdk
   build_profile=optimized
   loader=@apache-mynewt-core/apps/bleprph

It seems like the restore command isnt working??? Here is the working nrf52dk showing the correct magic first byte

(gdb) x 0x8000
0x8000:    0x96f3b83c
(gdb) x 0x42000
0x42000:    0x96f3b83c
(gdb)

And both my nrf52840pdk and @mlaz's show no errors, but the second magic (and indeed the entire image) is missing on device

(gdb) x 0x82000
0x82000:    0xffffffff
(gdb) x 0xc000
0xc000:    0x96f3b83c (edited)
