It's always safest to reset the target before writing flash to get it
into a known state.
Thanks, solved,
there is an errata out for stm32f405, says device can't be programmed
without NJTRST connected.
So i connected (was simpler) the NRST the jtag NRST pin, and all works
perfect.

device id = 0x10016413
