flash download stops BDM

Started by George Hollinworth ACE December 19, 2005

I am using cosmic ZAP icd 6812(paged) to flash download to the HCS12DP256
chip through the
P&E multilink USB BDM. The target is the freescale M68EVB912DP256.

I have been loading to the target for months.

On the last download, the ZAP was incorrectly set to hc12dg128. The flash
showed an error almost at the end of the load sequence. Then the BDM
disconnected and I cannot connect to that target anymore. Looks like the
BDM has been turned off.

Is this possible?
Is there a way to recover?

Thanks,.

Sounds like you secured the device. Download a copy of unsecure_12 from
P&E's website at www.pemicro.com and use it to unsecure your part.
