C2H problem

Question

I met a problem in using C2H acceleration.

My chip is Altera's EP1c6q240.And my quartus project's compilation report show that the LE source is 66%.

But I want to accelerate my some function in my program.I put the function as a single function in .c file.But whichever function I accelerate, the result is all failed.

Below is the failed information:

/cygdrive/c/altera/kits/nios2_60/components/altera_hal/HAL/inc/sys/alt_flash_dev.h:82:PARSE ERROR, /cygdrive/c/altera/kits/nios2_60/components/altera_hal/HAL/inc/sys/alt_flash_dev.h line 82 column 1

Thank you for your advise.

If someone know the solution, please send message to me with my mailbox:gaurson@163.com.Thank you very much!

Are you trying to accelerate something that pulls in the CFI flash drivers? If you are looking to improve computational performance I would look for something else to accelerate besides flash accesses.

To debug this I would first switch to the software only implementation and make sure that compiles properly first.

I just went to line 82 in that file and found a struct. Take a look at the C2H user guide and near the end you'll see what the tool doesn't support (pg 113/118) here:

I hope that helps
