ICE-1000 emulator does not recognize custom BF-547 board

Hi,

There are a few possibilities why you are encountering this error message. Although you mention your custom board is based on the BF-547, can you please confirm the JTAG section of the board complies with the Analog Devices JTAG Emulation Technical Reference guide, EE-68:

Do you have access to a BF-547 EZ-Kit, or any other type of board? If you do, please let us know if you can connect without any problems to these boards.

Have you ever been able to connect to this board without any problems? On occasions, target connection errors can be caused by the processor booting corrupt code. If possible, please try changing the boot mode of the processor and let us know if this has any affect on the behavior you're seeing.

Please read through our Emulator Troubleshooting Guide and let us know the results of the troubleshooting steps it advises.

Please refer to the below EE note for VDSP++.

Hi:

Thanks for your reply. This problem went away after shortening the JTAG cable length (to 1 inch) between the target board and ICE-1000 emulator.
