Hardware acceleration integration starts with no apparent reason

Hi,

I have a SDSOC project that uses a couple of accelerated functions that are well confined in separated modules. Sometimes it happens that by changing something very simple in the software code, like a printf or a parameter into a sw function, when I recompile the hardware acceleration integration process restarts again with the subsequent long times for the bitstream generation. I cannot figure out why this happens, also because it seems very random. Any suggestion?

Thanks in advance

Hi @dat63

You can disable build automatically option.

Navigate to Project->Build Automatically and uncheck the option

 

Best Regards,

Nutan

Re: Hardware acceleration integration starts with no apparent reason

Hi Nutan,

the option you mention is not enabled and has nothing to do with what I was trying to say but maybe I was not clear enough. I am saying that sometimes even if I make a simple modification in the software code (not in the hw accelerated functions) the build process performs a complete bitstream generation instead of building the .elf only as I would expect

Best Regards

Re: Hardware acceleration integration starts with no apparent reason

Hi dat63,

did you find a solution? I have the same problem. It appears to be random for me. Even though i just change a std::cout line, sometimes the Hardware accelerator integration starts while building the project.

I tried the option "-mno-bitstream" without success.

Best regards.

Hi,

I am sorry but I did not find any solution for this issue. I gave up and I live with it, even though it is very annoying sometimes
