MPSoC的MAC支持1588。在Linux Kernel的配置項(xiàng)中使能CONFIG_MACB_USE_HWSTAMP,并在Linux rootfs添加Linux ptp/ethtool,就可以運(yùn)行1588的軟件命令ptp4l。
PetaLinux下,配置Linux rootfs命令是petalinux-config -c rootfs。1588在Linux用戶態(tài)的應(yīng)用程序軟件包是Linuxptp,可執(zhí)行文件是ptp4l。
1在zcu106之間運(yùn)行1588
下面的命令,在zcu106之間運(yùn)行1588。運(yùn)行順序是先在第一塊單板(master)啟動(dòng)1588 master;再在第二塊單板(slave)上啟動(dòng)1588 slave;接下來在第一塊單板(master)終止1588 master,模擬1588 master故障;最后再在第一塊單板(master)啟動(dòng)1588 master。
1.1. master
1588 master的命令是ptp4l -i eth0 -m。運(yùn)行記錄如下:

在1588 slave的打印中可以看到,slave先選擇外部時(shí)鐘master 000a35.fffe.04d238。當(dāng)外部master退出后,再選擇了本地時(shí)鐘,0651e5.fffe.c27188。當(dāng)外部master正常后,又選擇了外部時(shí)鐘master 000a35.fffe.04d238。
時(shí)鐘的標(biāo)識(shí),是網(wǎng)卡的MAC地址。
master offset表示主從端時(shí)間差,單位是ns。s0,s1,s2 : 表示1588的不同狀態(tài),s0表示未鎖定,s1表示正在同步,s2表示鎖定。
2PC機(jī)上運(yùn)行1588
也可以在PC機(jī)上運(yùn)行1588。首先在master和slave的PC機(jī)安裝1588的Linux用戶態(tài)應(yīng)用程序,Linuxptp。
