[microblaze-uclinux] Error open file

[ravi kishu <ravvigadu@xxxxxxxxx>]

Hi Dear,
  
  -----------       I runned the video decoder program on the uclinux 
  
                1)  After making the make , make romfs , make image successfully , I copied these images folder from petalinux-dist to the referencedirecotory of edk project.

                 2)   Then I downlaoded the bit stream from the Edk window ..... it was done .

                 3)   Now  I open the hyper terminal and   "launch XMD "  then it opens the XMD window 
 
                4)    Now I did cd images 
 
                5)    Then I did " dow -data image.bin 0x8c000000 "
 
                 6)   After that   con 0x8c00000

                   Then it was done successfully and showed the processing the hyper terminal

                   now I typed H264_dec( which is in the make file APP)  and press teh enter key so the executable file is working

                  But my Problem is how to give the input file to this and how can i get the output file 

                  Later i copied  "test.264" file and "decoder.cfg" file to the petalinux-dist/romfs/mnt/ 

------      and again follow the same procedure like above  , i.e, make romfs make image then no errros so dowwload the bitstream and......( steps 1 to 6)

                 now in the XMD > cd images 
                       > cd ../mnt
                       > H264_dec decoder.cfg

                 then it was saying 
               Error open file test_dec.yuv

-----      then  I went to the romfs directory/mnt/ 
                 created the test_dec.yuv and did the same thing.( steps 1 to 6)  make romfs make image .......

                 again in the XMD if we give 

                 # H264_dec decoder.cfg   then it was giving the same error 
                     
                 Error open file test_dec.yuv     

again I tried like below


# cd /mnt/
# H264_dec -i test.264 -o test_dec.yuv
Error open file test_dec.yuv
# H264_dec -i test.264 -o ted.yuv
Error open file ted.yuv
# H264_dec -i test.264 -i test_dec.yuv
Error open file test_dec.yuv




so how can i give the input file to my image so that it will take the input and give the output , and from where i can take the output . Please assisat me in this regard



Thanks in advance 
Ravi
