hello,

i m using codevelopper to accelerate some calculations, when the hardware module is associated to a virtexII pro platform with microblaze processor it shows me en error in terminal window "malloc failed malloc failed"

i have tried some exemple ( helloworld, fft256, blackschols ) and just the helloworld exemple is showing the right result, the other no!

i m using opb bus, i have tried to enlarge heap end stack memory, using sdram memory and no change always "malloc failed". the software ( i mean xxxx_sw ) is welly written ane verified.

If somone can help ?

Hi,

What is the base address of the heap memory? If it is zero, then the co_process_create function will interpret the result of malloc as NULL and print the error message you describe.

Another possible source of the problem is an older version of Xilinx EDK. Which version are you using?

Ralph

I tried your proposition but still the same error !

Have you run the XMD debugger on the MicroBlaze to see which function is causing the "malloc failed!" messages to be printed?

Which version of CoDeveloper are you using, and which PSP have you chosen when building the example projects?

Thanks,
Ralph

Hi bizertino,

Can you send us your EDK project for a diagnosis? Please clean your project first to keep the transfer size smaller.

Thanks,

Hi bizertino,

You can post the zipped project files to the forum as an attachment. If you prefer to continue our discussion privately, sending emails to support@impulsec.com is fine. No additional information is needed as long as we know it's from you, and related to this forum thread.
