ADuC7023 Eval Board not flashing

Hi,

I have been using ADuC7023 Eval board 40-lead rev.B for about a week now. Got no problem debugging and downloading to it using mIDAS-Link until today. I just debugged using the latest FW with just a slight modification like toggling P0.7 but in that last flash J-link cannot connect to it until now. Kindly advice on how to fix this. Thanks.

  • Hi,

    Thanks for replying. I haven't mentioned that I also tried that steps 1 to 5 of I2C Programming interface. But tried it again anyway. Got the same error when I tried it the 1st time.

    We purchased a new board. It would be great if this could be fixed and to know the cause of the problem so we can avoid in the future.
