AWR2944: awr2944解锁步运行？

Other Parts Discussed in Thread: AWR2944

Ti的工程师您好！

  我们目前基于awr2944在进行开发，awr2944一共有r5-0,r5-1,dsp三个核，在默认的demo中，r5-0与r5-1是lockstep模式运行的，请问一下，如果我想让r5-0与r5-1单独运行，请问我该如何操作呢？我浏览了该论坛其它相关回答，说是分开运行不支持，但是我阅读了sdk相关文档，又是支持的，mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_awr294x_09_00_00_15\examples\networking\enet_layer2_multi_channel\awr294x-evm也提供了r5-0，r5-1双核单独运行的demo，sbl会自动根据appimage中的程序数量，切换至不同的模式，如果我想要r5-0,r5-1单独运行，是不是建立r5-0，r5-1,dsp三个工程就可以了，最后，如果要3核调试，该怎么进行操作？期待您的回复！

    是的，要使 R5-0 和 R5-1 单独运行，步骤包括：

    创建独立的工程项目、加载程序到各自的核心、配置启动加载程序（SBL）、多核调试

    好的，谢谢，问题已解决，修改ccs_debug程序后3个核也可以正常调试，但是内存r5-0与r5-1,存在一些问题，r5-1在不使用TCMB的情况下，可以正常运行，但是使用TCMB后，会跑飞，我的内存配置如下，请问一下是否存在问题：

    r5-0:

    }

    r5-1:

    检查一下内存访问
