器件型号：DRA756

工具/软件：Linux

您好！

HW：定制 VAYU 板。

我正在将 SDK 从 GLSDK 7.04移植到处理器 SDK 3.02。
目标板基于 DRA7X_EVM (VAYU 703761-1031)、没有太多差异。

我没有遇到 GLSKD 7.04问题。
但是、在应用处理器 SDK 3.02后、USB1器件模式不工作。

在 u-boot 中使用"ums 0 mmc1"命令时、在主机 Linux PC 上可以找到小工具驱动程序和其他目标的停止。
内核加载后、我可以使用 USB1作为器件模式。

但如果没有 u-boot 命令、我无法使用器件 USB1端口。
当我使用以前版本的内核配置和设备树(基于 GLSDK 7.04)使用相同的 u-boot 进行测试时，情况良好。
(我通过更改器件树测试了主机模式、它在主机模式下工作正常。)

我认为内核配置或设备树肯定是错误的。
我已经检查了时钟、稳压器电源等
但我不能弄清楚是什么问题。
还有其他建议或提示吗？

谢谢你

内核配置

我认为、如果您可以通过脚本自动执行 g_multi-modprobe、我认为您将能够检测到它。

您好 Dwarakesh R

嗯。我认为您理解不正确。

问题不是小工具驱动程序的 modprobe。

即使我执行了 modprobe 的脚本、USB1的器件模式也不起作用。

我的意思是、只有 lsmod 的日志才会被执行、而不会有小工具驱动程序的 modprobe。

因此、我在执行小工具驱动程序后添加了 lsmod 命令的日志。

在没有 uboot 命令的 modprobe 命令后、器件模式不工作。这是问题。

哦、好了。您是否能够观察到 USB 寄存器在工作用例和非工作用例(给定和未给出 Uboot comand 时)之间的任何变化。我怀疑 USB 的 FCLK 未设置差异。
