Programming Flash Memory

Hi.
I am trying to programm flash memory (cfm) via gdb, but it errors. Is
flashing still not supported, or do I do something wrong? When I try to
flash via the P&E-Tools or via the CFFlasher from Freescale it works. My
target I want to flash is a mcf52235. Below I copied a complete gdb
session, for the case that helps.
Thank you for any help and advice.
Kay
