I have done some software projects with CoDeveloper,I have found these errors as blow:

1.HW_STREAM_WRITE HW_STREAM_READ:
such as: HW_STREAM_WRITE(test_producer,red_pixels_out,pBitMap[i++]); ( in the EdgeDetect_2 of Toturials)
the compiler of edk show erros blow:
/cygdrive/c/G/gc19861210/EdgeDetect_2/EDK/code/EdgeDetect_sw.c:128: error: expected ':' or ')' before 'p_test_producer_red_pixels_out'
2. creat_stream creat_process failed

it shows that "malloc failed!" ,and I figure out it is the problem of creat_stream() creat_process ()

And it's so strange that I have not encount these probloems in other projects .


Can you tell me why? how to solve them? Thanks a lot!

You are you using the APU correct? If so, are you including "apu_if.h" which gets exported as part of the driver?

How big is your heap? You can set the heap size using the linker script.

apu? sorry, I use mocoblaze in my system , It seems that there is no apu . And ,Why I have not these problems in other project? Thanks

Hi,
What other projects and in what version(s) of CoDeveloper? Your projects or examples? And all MicroBlaze?

For the compile error, it is a matter of names. Check to make sure the names match what is in the generated "fsl_if.h" file (I am assuming your are using FSL with MicroBlaze given the error which would be similar to PPC-APU).

For the "malloc failed!" error, there is a long known error with Xilinx's implementation of malloc() (do a search on the forums here or Xilinx's site for more information) for for the MicroBlaze such as the heap does not get automatically free'd at reset causing memory to "leak".
