Hello,

it seems like I made a huge mistake on use of the flash protection descriped here: http://www.infineonforums.com/threads/1013-Flash-Protection-for-TriCore?

Unfortunately I locked the device and can't even connect the MemTool to it any more. DAS says "DEVICE_LOCKED".

Is there anything I can do, to get access to it again?

Hope you can Help...

I made the same misstake but on TC1793.
I Wonder if it's possible to fully erase flash or if I should replace processor.

Hi Guys,

Erasing the UCB can reset everything.

However did you guys implement additional code to erase the UCB? Pls drop me a PM with your email address so that I can contact you directly.

Best Regards
Travis

[#6]

I can't erase the USB, because I have not access to the flash. So i can't load new code to the device.

1. which debugger is used?
2. What is the hardware configure for TC277?
If use ineternal flash, no problem for JTAG/DAP connection. The customer can use the same flash driver(program,erase) for DFLASH and UCB.
