How to insert the interrupt vector table in a C6202 DSP/BIOS confige file?

Z-SEED

I use a DM642 board with a C6202 DSP/BIOS confige file for some reason. Now I need to open the interrupt GPIO_Interrupt_0 in DM642, which is not shown in C6202 DSP/BIOS confige file. What should I do to achieve this functionality?

I used to use the function C64_plug, but I can't debug it. The error code shows that C64_plug is a undefined symbol. How to use C64_plug correctly?

Thank you very much for you support. I am on-line waiting for reply.

You need to start from a DM642 seed file. You will never have access to C64 APIs as long as BIOS thinks you're on a 62x device. What version of BIOS are you using? Is this 4.x (cdb based rather than tcf based)? If so, an easier way to make the change might be to update to the latest BIOS. It will convert your existing cdb to a tcf file and at that point you will be able to edit text to tell it to use a DM642 seed instead of a 6202 seed.

I used BIOS5.31.2. How about C62_plug?

I think Brad's point is that at best you are looking at a work-around rather than something guaranteed to work long-term. Creating a new BIOS Configuration file for a DM642 target should be fairly straightforward, so please let us know if there is any reason you cannot do this.

I change the interrupt source, and the problem is sloved. Thank you very much.

But I still want to know if there is any way to slove this problem in software? In other words, I just want to know how to plug a interrupt in a BIOS configure file in main function.

Take a look at the HWI_dispatchPlug function in the BIOS API Reference Guide.

Tim, many thanks for your answer.

Could you tell me how to use C62_plug function, please? I used it with the head file "c62.h", but CCS said that the C62_plug is a undefied symbol. Is therr any lib file I should add?

Thank you very much.
