TDA4VM中的每个核都有自己的bootrom吗,在哪里可以找到对应bootrom的内存划分吗。比如MCU_0_0的bootrom和MCU_0_1的bootrom分别在哪片内存?

不是每个核都有自己的boot rom,有两种the MCU ROM code和DMSC ROM code,具体可以看TRM文档4.1.1 ROM Code Overview。

1.目前支持lockstep模式。
The Linux SDK currently operates MCU R5F in LockStep mode, and there is missing support to boot the MCU R5F Core1.
