AUTOSAR开源OS——Trampoline的编译与使用（二）

环境准备

viper准备

如果没有viper配置的话，会出现如下报错：

Error: VIPER_PATH is not defined. Exiting
Exiting virtual platform.

因此需要正确配置viper，viper在trampoline中已经给了，就在源代码的根目录下面，需要执行如下命令进行配置

cd viper
make
export VIPER_PATH=`pwd`

此时再执行相关任务就不会出现上述报错了

任务配置

可以参考goil官方手册，这里贴一个案例demo作为参考，除了基础的applicatin和task等，还有一个IOC的案例

OIL_VERSION = "4.0";IMPLEMENTATION trampoline {/* This fix the default STACKSIZE of tasks */TASK {UINT32 STACKSIZE = 32768 ;} ;/* This fix the default STACKSIZE of ISRs */ISR {UINT32 STACKSIZE = 32768 ;} ;
};CPU only_one_periodic_task {OS config {NUMBER_OF_CORES = 1;STATUS = EXTENDED;BUILD = TRUE {APP_SRC = "ioc.c";TRAMPOLINE_BASE_PATH = "../../..";APP_NAME = "ioc_exe";LINKER = "gcc";SYSTEM = PYTHON;};};APPLICATION receiver_application {TASK = receiver;ALARM = check_every_seconds;COUNTER = SystemCounter_App0;};APPLICATION sender_application {TASK = sender;ALARM = please_send_a_message;COUNTER = SystemCounter_App1;};APPMODE std {};COUNTER SystemCounter_App0{};COUNTER SystemCounter_App1{};ALARM check_every_seconds {COUNTER = SystemCounter_App0;ACTION = ACTIVATETASK { TASK = receiver; };AUTOSTART = TRUE { APPMODE = std; ALARMTIME = 100; CYCLETIME = 100; };};ALARM please_send_a_message {COUNTER = SystemCounter_App1;ACTION = ACTIVATETASK { TASK = sender; };AUTOSTART = TRUE { APPMODE = std; ALARMTIME = 350; CYCLETIME = 300; };};TASK receiver {PRIORITY = 1;AUTOSTART = FALSE;ACTIVATION = 1;SCHEDULE = FULL;};TASK sender {PRIORITY = 2;AUTOSTART = FALSE;ACTIVATION = 1;SCHEDULE = FULL;};IOC my_ioc_name {DATATYPENAME uint32 {DATATYPEPROPERTY = DATA;};SEMANTICS = QUEUED {BUFFER_LENGTH = 5;};
//    SEMANTICS = LAST_IS_BEST {
//      INIT_VALUE_SYMBOL = AUTO;
//    };RECEIVER rcv {RCV_OSAPPLICATION = receiver_application;};SENDER snd {SND_OSAPPLICATION = sender_application;};};
};
