One or two bank memories issue

I am testing "hello_wolrd" example for cyclone V by using OpenCL sdk and "c5soc" profile board on the compiler. I followed the getting started guide and it works perfectly.  

 

However, when I try to use another board profile as "c5soc_sharedonly" this does not work, the issue is exposed at the moment of running the host application and this indicate a "different name of device issue", so based on this issue, I edit the "board_spec.xml" name field to change just for c5soc (deleting "_sharedonly" part), and also the folder of the board was edited with c5soc only. By avoiding to have conflict with c5soc original board profile, I move the folder to another place. And again I compile but this time using "c5soc" board profile ( c5soc_sharedonly edited) its compile correctly but this time when I try to run host application linux get freezed.

I am thinking that the RTE running over SOC-FPGA linux os is just compatible with two banks of ram memory project, because the c5soc_sharedonly profile has one bank memory and it is the only difference with c5soc board profile. 

 

Someone has more information related to this. I will be deeply thankful for any help.

I got the solution.  

 

As I am using other c5soc profile board, it is needed to reprogram with aocl 

1) Run comand: "aocl reprogram /dev/acl0 hello_world.aocx" 

2) Then you can run the c5soc shared only project: "./host" 

 

P.D: Always check the profile board that is running with coamand "aocl diagnose".
