hello, everyone. I am using omap3530 board,and dsplink version is dsplink_1_65_00_02 . and my os is linux-03.00.01.06.

I have finish the build of dsplink environment and the compile of the samples . the samples can run in the linux . I also change the sample and write new application (gpp and dsp) . the application can run in the linux . 

but I find a strange appearance.  when linux is begin and dsplinkk.ko is insmod , the first application can run OK in the linux . and  the application can run many times. but if I can another application ,the another application hang in the PROC_start .and no any print info.  both the sample and  my application is  this appearance. these samples can run in the first times ,but  why it hand  in the PROC_start  if it  run after one application run ?    I changed the bootmode from  DSP_BootMode_Boot_NoPwr to DSP_BootMode_Boot_Pwr . but it not work .
