Unable to open GEL file

Hi,

After bulit the project, I tried to debug it. However, CCS says that "unable to open GEL file", although I have put the GEL file in the project

You need to include the GEL file in your target configuration. Please check the section Advanced target configurations of the CCSv5 Getting Started Guide.

And then CCS also says that "ICEPICK_C: Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.520.0)".

This error indicates the device may not be powered up correctly, as the emulator is failing to properly read a register on the internal JTAG router of the C6748 device (called ICEPICK). I would carefully inspect all the connections, as well as check if the C6748 is being held in reset by an external device - additional details are at the page below:

Another tip is to connect to the device manually instead of using the green bug button. For that, check the same section of the CCSv5 Getting Started Guide sent before.

Hope this helps,

Hi Rafael,

Thanks for the reply, the problem is solved.

By the way, I would like to know the setting of DIP switch on C6748.

As shown in the brochure along with the TMS320C6748, the DIP switch is set as 2, 3, 4 on and 1, 5, 6, 7, 8 off.

This setting is correct for finger print and face detect demos.

Is it also correct for other cases in developing TMS320C6748?

Thanks.

Best regards,

PP
