工具与软件：
有时、从暂挂模式唤醒后电话不显示。 当没有显示时 寄存器 F6 = 40。 这种现象的原因可能是什么？
您好！
请查看以下调试指南：
e2e.ti.com/.../faq-sn65dsi86-sn65dsi86-black-screen-debugging-guide
我已验证设置是否与 EDID 面板配置相匹配、但问题仍然存在。 接下来、我可以采取哪些步骤来调查问题背后的原因？
以下是我的设置和 EDID。

您好！ 您能否检查系统是否遵循数据表中的暂停模式说明。 它表示 SUSPEND 置为有效之前和之后都应有有效的 REFCLK。 此外、您能否通过内部图形生成对此进行测试、看看是否仍然出现这种情况？ 还请共享 工作情况和非工作情况的0xF0 - 0xF8寄存器读取、以便我们检查是否还记录了其他错误。 此致、 Ikram
调试后、无法重现不显示的问题。 但在正常显示期间、寄存器 F8始终设置为1。
这是否正常？ 如果不能、我可以采取什么措施来解决它？
遵循 F1~F8
F0=0 F1=1 F2=0 F3=0 F4=1 F5=0 F6=0 F7=0 F8=1
谢谢
您好！ 0xF8寄存器位0表示链路训练成功、这表示 DP 输出已进行链路训练且正在工作。 挂起模式问题的信息、这是否重复出现？ 它出现的频率有多高？ 如果问题再次发生、您可以共享这些寄存器的日志以检查它遇到了哪种类型的错误。 此致、 Ikram
