器件型号：TDA4VM 尊敬的 TI 团队：
我尝试使用 OSPI 来缩短启动时间，
我使用了 TI 的演示("SBL_cust_img"和"CAN_BOOT_APP_MCU_RTOS ")，并尝试修改了演示(CAN_BOOT_APP_MCU_RTOS)，以便它可以跳转到我的应用程序并启动 QNX。
启动过程为：(SBL_cust_img -> CAN_BOOT_APP_MCU_RTOS ->启动我的应用和 QNX)
a. SBL_CUST_IMG：启动 MCU1_0/MCU1_1
b. CAN_BOOT_APP_MCU_RTOS：我修改了它，添加了" status = OSPIBootImageRate (&k3xx_evmEntry、OSPI_OFFSET_APP)；"以读取我的应用文件；
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;
}
然后调用 SBL_SlaveCoreBoot (MCU1_CPU0_ID、0、&k3xx_evmEntry、SBL_Request_CORE)以跳转到我的应用。
它可以正确跳转到我的应用程序并启动 QNX；但是当我删除"Task_sleep（4000)"时、它将导致 QNX 启动失败、错误为:ti_sci_recv_message、无法接收消息

我的问题是：
1.删除"Task_sleep (4000)"时为什么它启动 QNX 失败？ 这是因为 MCU 跳转到另一个应用程序而导致 sci 服务器关闭了吗？
2.是否有其他方法可以帮助我们解决这个问题？ 我们希望引导加载程序可以跳转到我的应用程序并启动 QNX
