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。

回复 陈慧:

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?
