在虛擬機(jī)可以正常運(yùn)行官網(wǎng)提供的 openocd 工具，但是將其移動(dòng)到docker環(huán)境后，和主機(jī)共享設(shè)備。Docker 內(nèi) lsusb 可以識(shí)別出來usb設(shè)備

找到問題了??！

Docker 內(nèi)執(zhí)行下面這條指令出現(xiàn)?

Couldn't?open?device,?some?information?will?be?missing

是因?yàn)槲沂褂玫牟皇?root 用戶，加上 sudo lsusb -s 001:003 -v 就正常了。

因此，如果需要執(zhí)行 openocd 的話 也需要加上 sudo openocd -f wch-riscv.cfg 就正常了??

希望我踩的坑，對(duì)大家有幫助。

Docker 的好處就是搭建的環(huán)境不會(huì)對(duì)宿主機(jī)有影響，畢竟 ./start.sh 會(huì)往宿主機(jī)里面塞東西....

sudo 是懶辦法吧，歸根結(jié)底是權(quán)限問題。

你所嫌棄的“往宿主機(jī)里面塞東西”其實(shí)就包含了權(quán)限配置啊，讓 Link-E 的組是 plugdev，然后你用戶也加入這個(gè)組，就可以正常訪問了。

docker的USB熱插拔支持還是挺差的。

2017年有一篇?https://pic.huodongjia.com/ganhuodocs/2017-08-18/1503028636.63.pdf?提到用mknod加載，我也是這么干的，確實(shí)能支持新插入硬件。不知道有沒有更好更簡單的辦法。
