Setting up uvision4 debugger with Cortex-M1 on Altera Cyclone III

I am trying to setup the uvision4 debugger to communicate with Cortex M1 on Altera Cyclone III through the USB JTAG interface. I have observed from the Cortex-M1 development kit that this can be done by instantiating the Virtual JTAG megafunction and implementing a glue logic to interface the Virtual JTAG with the Cortex-M1 RTL. Unfortunately, the Verilog description of the glue logic is not visible.
Can anyone give me some pointers on how to go about designing the glue logic between Virtual JTAG and Cortex-M1? Or is there another alternative to this? Thanks.

Hi there,
Are you using Cortex-M1 Verilog RTL source, or Cortex-M1 Altera development kit?

Hi Joseph,
I am using Cortex-M1 Verilog RTL source code. I have generated the bitstream using Altera tools and downloaded it onto the Altera FPGA. However, uvision4 is unable to detect the core on the FPGA. I am pretty sure that I have generated the bitstream correctly.
When I analyzed the files provided by Cortex-M1 Altera development kit, I realized that they have instantiated the Virtual JTAG megafunction and implemented a glue logic to interface the Virtual JTAG with the Cortex-M1. This glue logic is encrypted so I have no idea how it works.
Thanks and regards,
Siew Kei

I have discussed with the engineer who worked on this. When Cortex-M1 was developed, the Virtual JTAG detail specification was not open to public. As a result, we were unable to include the glue logic to the Cortex-M1 RTL package.
You should be able to bring out the JTAG/Serial Wire signals to the FPGA top level (you need to add a tristate buffer to SWIO), then you should be able to connect it to the debugger using Keil ULINK, Segger J-Link or other debuggers, using this separated JTAG interface.
Alternatively you can contact our support team to see if we can provide the detail of this glue logic to you.

Hi Joseph,
Actually, we are trying to get uVision4 to communicate with Cortex-M1 on the FPGA through the USB ByteBlaster. This is possible for the Cortex-M1 Altera development kit.
I will contact the support team to see if they can provide the glue logic. Thanks the suggestions.
Regards,
Siew Kei
