为了方便多人同时开发，我们在 j7200_evm BOARD上，尝试用【MMCSD+SBL】的方式启动调试Gateway Demo，结果不是所有核都能正常启动（MCU2_0未启动）。
想确认一下TI目前的Demo是否支持这样的启动方式？如果支持的话，我们的配置文件还有哪些地方需要改进。
【MMCSD+SBL】启动方式：
Boot Mode：MMCSD
Boot File：SBL
tifs：/packages/ti/drv/sciclient/soc/V2/tifs.bin
应用程序：combined.appimage（使用combined_appimage tool生成的多核Image）
生成combined.appimage使用的文件：
can_traffic_generator_app_mcu1_0_release.xer5f
app_remoteswitchcfg_server.xer5f
can_eth_gateway_app_mcu2_1_release.xer5f

Gateway Demos 不支持SD card boot mode. 只支持OSPI和CCS boot mode。

感谢回复：
我仍有如下两个疑问：
1、我理解multi-image从SD卡启动和OSPI启动只是启动介质不同罢了，同样的mult-image在OSPI能启动，那么在SD卡不也应该能启动吗？
2、Gateway Demos 不支持SD card boot mode，是哪个参数决定了不支持SD卡启动呢？
