66ak2 evm RBL

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！

Nancy Wang：

参考以下链接中关于prsc-errors的总结，是自制板吗？可能是硬件问题导致的。

Nancy Wang：

请问arm ROM的代码是从哪边看到的？方便分享一下链接吗？

回复 Nancy Wang:

arm ROM的代码，就是在ccs环境中 反汇编窗口 看到的。

目前我手头没有这块板子，没办法直接看，源码在哪里可以下载的？
