Hi.How can I use DVTB?

The evm is dm355evm.

# ls                                                                                                                                                
cmemk.ko          dvevmdemo         encodedecode      mapdmaq                                                                                       
data              dvtb-dm355        encodedecode.txt  thirdpartydemos                                                                               
decode            dvtb.cfg          encodedecoded     web                                                                                           
decode.txt        encode            interface                                                                                                       
dm350mmap.ko      encode.txt        loadmodules.sh                                                                                                  
# ./dvtb-dm355                                                                                                                                      
./dvtb-dm355: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory                      
#

What can I do ?

    Does your filesystem have /lib/libncurses.so.5 in it?
    Secondly, I presume you have performed the steps in the DM355 DVEVM Getting Started Guide (SPRUF73) to build the DVTB (ie. Section 4.8)?
    If so, the binaries that need to be copied into /opt/dvsdk/dm355 are dvtb-d and dvtb-r.

    Hi,


    Please follow the DVTB build instructions as in the DM355 DVEVM Getting Started Guide or the DVTB user guide (Sec 2.2).

    Once the build is successful, two binaries dvtb-r and dvtb-d will get created in the DVTB source directory.

    (dvtb-r is the release build that will run with minimum logs for any use-case. dvtb-d is the debug build that will run with full logging.)

    You would need to copy the dvtb-r and/or dvtb-d to the target directory /opt/dvsdk/dm355

    dvtb-scripts directory will have few scripts which can be taken as reference for running the required use-cases.
