我将 Altera 的 github 存储库（最近更新的主分支）中的 linux-socfpga 与我的 DE2-115 FPGA 一起使用。 jtag 配置的输出是：
$ jtagconfig1) USB-Blaster [2-2]
020F70DD EP3C120/EP4CE115
我想知道它是否可以找到我连接的 USB 存储器？当我运行 lsusb 时，什么也没有出现。也许是FPGA设计错误？

在 menuconfig 中我有以下设置。
答案1
部分答案：
这用户手册第 9 页显示有两个 USB 端口连接到飞利浦 ISP 1362Host/Device/OTG芯片，一个端口连接一个FTDI FT245。
启动日志显示您正在加载通用（Intel 兼容）EHCI 和 OHCI 主机驱动程序，以及fotg210_hcd（以错误的顺序）。所以这是行不通的，你没有任何驱动程序来访问你的 USB 端口。
这USB 设备树绑定然而，这些芯片没有明显的文件，谷歌搜索了一下说 ISP 1362 可能已被弃用。
因此，(1) 通过查看主板来找出主板上实际的 USB 芯片，(2) 找到它们的兼容驱动程序，如有必要，可以查看或grep查看已安装在某处的 Linux 树的源代码。
