TDA4VL-Q1: 锁步模式切换分离模式报异常

guibing liang

Part Number: TDA4VL-Q1

目前bootload开发的方案，sbl加载bootload，再由bootload加载app。三者都是运行在Mcu1_0上，bootload加载到DDR及部分的OCMC。当bootload将app从EMMC加载到DDR后，MCU1_0需要从锁步模式退出到分离模式，此时会提示操作失败，请问有没有解决办法，谢谢。

请及时跟进英文论坛的回复：

There are 3 components: SBL, BootLoader and App and three of these components run on MCU1_0.
You want to boot SBL and Bootloader in Lockstep mode but when loading app on mcu1_0 you want to load in split mode?

What is the intent of using split mode for the app? Are you loading different firmware on mcu1_0 and mcu1_1.
Also, can you please share the steps you are following to switch between split/lockstep mode?
