• 国内开源ARM TrustZone安全内核

    Liwenhao
    Liwenhao

    Hi,大家好。

    我们团队花了很长时间实现了基于ARM TrustZone的安全内核T6:t6_overview,现在代码已进入稳定版本,目前支持三星SoC、ARM Versatile Express,正在支持Freescale,T6正计划开源,但不知道国内这方面的需求怎么样。

    板上大神不少,希望大家能给出点意见或批评,让我们能够有动力将T6一直维护下去。

    谢谢。

  • JTAG工具如何让CPU停下来?

    chinatiger
    chinatiger

    hi, experts:

    通过JTAG 接口,debug ARM Cortex-A7平台时:

    JTAG tool与CPU Core连接后,通过halt命令,会让CPU停下来?

    这是如何做到的?会做一些CoreSight相关register设置吗?

    按我的理解:

    1. 当我们设置Software breakpoint / Hardware breakpoint时,才会做一些register设置。
