Build error

[reis220]

Hello everyone,

When i try to set up my only task to autostart after StartOS(), i can't build the code.

This is the excerpt of the code that triggers the build error:

Code: Select all

  TASK Task1 {
    PRIORITY = 1;
    AUTOSTART = TRUE { APPMODE = OSDEFAULTAPPMODE; };
    STACK = PRIVATE {
      SIZE = 1024;
    };
    SCHEDULE = FULL;
  };

When i switch AUTOSTART to FALSE, it stops giving me errors and builds correctly. Have you got any hints of what might be the problem?

Could you please report which build are you using?

Please also attach a minimal complete OIL file that trigger the error.

I am compiling using aarch64-linux-gnu-gcc and the petalinux working evironment. I've been following the instructions from here (http://www.erika-enterprise.com/wiki/in ... inx_ZCU102), because i want to use ERIKA in a jailhouse context with Ultrascale+ SoC.


This is my OIL configuration file:

Code: Select all

CPU mySystem {

  OS myOs {

    /* EE_OPT = "OS_EE_VERBOSE"; */
    EE_OPT = "OSEE_DEBUG";
    EE_OPT = "OS_EE_APPL_BUILD_DEBUG";
    EE_OPT = "OS_EE_BUILD_DEBUG";
    EE_OPT = "OSEE_ASSERT";
    
    CFLAGS = "-g -Wall";
    CFLAGS = "-I/home/joao/armageddon/libflush/libflush";
    CFLAGS = "-I/home/joao/Desktop/jailhouse_v0.10/inmates/lib/arm-common/include";
    CFLAGS = "-I/usr/aarch64-linux-gnu/include";
    

    CPU_DATA = AARCH64 {
      MULTI_STACK = TRUE;
      COMPILER = GCC;
      IDLEHOOK = TRUE {
        HOOKNAME = "idle_hook";
      };
    };

    /* SOC_DATA = NVIDIA_TEGRA_X1; */
    SOC_DATA = XILINX_ZYNQ_ULTRASCALE_PLUS; 

    KERNEL_TYPE = OSEK {
      CLASS = ECC1;
    };
  };
 
  APPDATA aarch64_jailhouse_hello_world {
    APP_SRC = "main.c";
  };

  
  TASK Task1 {
    PRIORITY = 1;
    AUTOSTART = TRUE { APPMODE = OSDEFAULTAPPMODE; };
    STACK = PRIVATE {
      SIZE = 1024;
    };
    SCHEDULE = FULL;
    //RESOURCE = SharedUartResource;
  };

};

I'm not sure if the following is the problem it's just a suggestion, since I cannot build for AARCH64, I don't have the environment set.

Since you have no APPMODE configured, you don't need to explicity states the appmode in TASK AUTOSTART field.

Try:

Code: Select all

  TASK Task1 {
    PRIORITY = 1;
    AUTOSTART = TRUE;
    STACK = PRIVATE {
      SIZE = 1024;
    };
    SCHEDULE = FULL;
    //RESOURCE = SharedUartResource;
  };

Now when i try to build it warns that there is no ee_oscfg.mk file, therefore it cannot build.

I've uninstalled and installed Erika and everything is working fine now (don't know which was the problem). You can close the thread if you want to.
