devo7e with V5.0.0 can't format inside 2M storage

hi ,guys ,i have updataed my devo7e to V5.0.0 half an hour before, but i found i can not enter into the main menu , it stoped at the mass storage interface , no matter i press "ent" to power on or not. just as pic shows.


And i can not formatting this mass storage . But i'm sure the "ent" kay has no problem , i have tested it , and before i updataed the new version ,it works well .
So how can i solve this ? Really appreciate for your hard work ! Thanks first !

ok. i reply myself . i found i need to remove CC2500 then updata the new V5.0.0 version , everything goes well , the reason is leaking of power supply ! i add another LDO for extra module ,

There have been changes in tx.ini and hardware.ini in nightly-build/5.0.
