Since PLM supports three priority tasks (Critical, High and Normal priority), below example shows how the user can create a high priority task within PLM

Code Block
languagec
int XPlm_PreBootTasksUserTaskHandler(void* Arg)
{
  XPlmi_Printf(DEBUG_PRINT_ALWAYS, "User task handler\r\n");
  
  return XST_SUCCESS;
}

int XPlmi_RegisterUserTask(void)
{
  int Status = XST_FAILURE;
  XPlmi_TaskNode *Task;
  
  Task = XPlmi_TaskCreate(XPLM_TASK_PRIORITY_0, UserTaskHandler, NULL);
  if (Task == NULL) {
    Status = XPlmi_UpdateStatus(XPLM_ERR_TASK_CREATE, 0);
  }
  
  XPlmi_TaskTriggerNow(Task);
  
  return Status;
}

In the above example code, XPLM_TASK_PRIORITY_0 is passed to the XPlmi_TaskCreate function along with the task handler to create a task with high priority. Similarly, If user wants to create a Normal priority task, XPLM_TASK_PRIORITY_1 needs to be passed as priority argument for XPlmi_TaskCreate function.

*This above size which we give here is basically the total Image store memory allocated where multiple PDI’s are stored once the PDI add request is made.
Eg:

A new <PDI ID> field is added to the Add & Remove Image Store IPI command

...

id_code = 0x14ca8093
extended_id_code = 0x01
id = 0x1

boot_device { imagestore, address = 12 }

image
{
name = pmc_subsys
id = 0x1c000001
partition
{
id = 0x2
type = bootloader
file = ./plm.elf
}
partition
{
id = 0x3
type = pmcdata,load=0xF2000000
file = ./pmc_data.cdo
}
}

Info

Note: All of the metrics are with compilation optimized for size (-Os) and LTO settings enabled for PLM BSP. This optimization settings are enabled by default.
