Message: 51403   

Hi All,

 

     I am using JPEG decoder(JPEG2000)  written in Assembly language for blackfin  BF561 processor and able to compile it for BF561 on x86 host. Here the main function written in C Language calls the assembly routine by passing arguments to it,but While executing it is giving  following errors,

<br style="color: rgb(51, 51, 255);" />Decoder: not found<br style="color: rgb(51, 51, 255);" />Here Decoder is executable file.<br style="color: rgb(51, 51, 255);" />

please could anyone suggest me  where i am wrong here.

 

 

 

Thanks and Regards,

Pavithra

Message: 51409    Hi Mike,

    Sorry for not sending the JPEG decoder files.I have attached the files here with this  mail,please go through.We are using the  JPEG2000 decoder test application given by ADI to test using VDSP.But here i am trying to port on uclinux.

Please tell me where i am going wrong.

 

In cycle_count.asm source file they have used two variables,

_Ret_Add, and  _Save_R7  I am not getting  what has to be  replaced by  these

variables.

 

And along with these files i am using another header file test_input.h

File is as below.

 

test_input.h

 

 

 

 

 

 

Thanks and Regards,

Pavithra

Message: 51430    the error string you said was displayed is not contained in any of those sources

 

you also need to change all of the arguments to the .section attributes as none of the VDSP sections match the standard names used by everyone else

 

please review the documentation on how to port VDSP code
