hello,
最近在研究 66ak2的arm端的RBL代码，有如下问题：
1. 同样的ccs环境，一块66ak2的开发板能同时连接 4个arm_A15 core，另一块开发板只能连接arm_A15_core0，TargetConfiguration已经配置好各核的gel。
连接其他core时，错误信息：
Error -6305
Error Generating to the target, PRSC module failed to write to a router register。
2. 在查看arm ROM中的代码时，发现
有读地址 0x2501040 + (core number<<3)，
有写地址 0x1000030 + (core number<<2), 0x100_0030为AXI2BUSM Master 地址。
不知以上操作有什么物理意义？
谢谢！
