Hello TI Teams:
I tried to use OSPI to decrease the startup time ,
I used TI's demo("sbl_cust_img" and “can_boot_app_mcu_rtos”) and i tried to modified the demo(can_boot_app_mcu_rtos), so that it could jump to my APP and start the QNX.
The startup process is:(sbl_cust_img -> can_boot_app_mcu_rtos -> start My APP & QNX)
a. SBL_CUST_IMG: to start MCU1_0/MCU1_1
b. CAN_BOOT_APP_MCU_RTOS: I modified it , I add " status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_APP);", to read my App file;
static int32_t OSPIBootStageImage(sblEntryPoint_t *pEntry, uint32_t address)
{
int32_t status = E_FAIL;
if ((NULL != address) && (NULL != pEntry))
{
if (address != MAIN_DOMAIN_HLOS)
{
# if !defined(MPU1_HLOS_BOOT_ONLY_ENABLED)
/* non-HLOS image */
// status = OSPIBootImageLate(&k3xx_evmEntry, address);
status = E_PASS;
# else
status = E_PASS;
# endif
}
# if defined(MPU1_HLOS_BOOT_ENABLED) || defined(MPU1_HLOS_BOOT_ONLY_ENABLED)
else
{
// status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_APP);
// AppUtils_Printf(MSG_NORMAL,
// "START H97 APP \n");
/* Load the HLOS appimages */
status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_A72IMG1);
if (status != E_PASS)
{
AppUtils_Printf(MSG_NORMAL,
"Error parsing A72 appimage #1 for HLOS boot\n");
}
else
{
status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_A72IMG2);
if (status != E_PASS)
{
AppUtils_Printf(MSG_NORMAL,
"Error parsing A72 appimage #2 for HLOS boot\n");
}
else
{
#if 1
status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_APP);
if(status == E_PASS)
{
//AppUtils_Printf(MSG_NORMAL,"START H97 APP \n");
//AppUtils_Printf(MSG_NORMAL,"Entry point = %x\n",k3xx_evmEntry.CpuEntryPoint[4]);
Start_App = 1;
}
else
{
AppUtils_Printf(MSG_NORMAL,"START H97 APP FAILED\n");
}
#endif
}
# if defined(LINUX_OS)
else
{
status = OSPIBootImageLate(&k3xx_evmEntry, OSPI_OFFSET_A72IMG3);
if (status != E_PASS)
AppUtils_Printf(MSG_NORMAL,
"Error parsing A72 appimage #3 for HLOS boot\n");
}
# endif
}
if (status == E_PASS)
{
/* Set the A72 entry point at the ATF address */
pEntry->CpuEntryPoint[MPU1_CPU0_ID] = ATF_START_RAM_ADDR;
}
} /* if (address == MAIN_DOMAIN_HLOS) */
# endif /* #if defined(MPU1_HLOS_BOOT_ENABLED)*/
} /* if ((NULL != address) && (NULL != pEntry)) */
return status;
}
and then call the SBL_SlaveCoreBoot(MCU1_CPU0_ID, 0, &k3xx_evmEntry, SBL_REQUEST_CORE); to jump to my APP.
It could jump to my APP correctly and start the QNX; But when i remove the "Task_sleep(4000)", it will lead QNX start failed, the error is :ti_sci_recv_message, unable to receive message

So my questions:
1. Why will it start QNX failed when i remove the "Task_sleep(4000)"? Is it because mcu jump to the other APP and it leads the sci server closed?
2. Is there has the other way to help us solve this problem? we want the bootloader could jump to my App and start QNX
