(Error -1015 @ 0x0) after the first flash

Other Parts Discussed in Thread: UNIFLASH

Hi,

i had started to load a programm to a TMS330F28069PZT at the first time.

At the first moment, every work fine, but at the moment where CCS5 startet to flash the controller the power supply collapsed, because i had set the current limited at a low level. 

I thought, no problem, load the programm again.

BUT, now i get always the error:

Error connecting to the target:

(Error -1015 @ 0x0)
Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible, and power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.0.872.0)

The JTAG connection work fine, the "JTAG DR Integrity scan-test has succeeded"

The cuircuit and the power supply is ok.

I tried to erase the flash with CCS Uni-Flash also, but i get only: 

15:38:10] C28xx: Erasing Flash memory...

[15:38:10] ERROR >> C28xx: Flash Programmer: Error erasing flash memory. Device is locked or not connected. Operation cancelled

Can anyone help me with my problem?!
