#83750 - Seciurity bits. Responding to: ???'s previous message |
Dear Jan,
Thanks a lot for your reply, Did you clear the security bits using serial (via bootloader), or parallel (using device programmer) programming? I am using new virgin chips and they show all 3 security bits unset /clear when read using flashmagic. When prgramming I chose option "Erase all Flash+Security bits" in Flashmagic to make double sure that all security bits are cleared but the problem is not solved. Regards, Prahlad Purohit |
