当我尝试将某些内容回应到/ sys / devices / platform / bone_capemgr / slots时 控制台冻结,CTRL + C,CTRL + Z没有动作。 Ubuntu分配来自: https://rcn-ee.com/rootfs/2017-04-07/flasher/BBB-eMMC-flasher-ubuntu-16.04.2-console-armhf-2017-04-07-2gb.img.xz
root@arm:~# uname -r
4.4.59-ti-r96
root@arm:~# sh -c "echo 'BB-UART1' > "sys/devices/platform/bone_capemgr/slots"
我清除了最终安装bb-cape-overlays
apt-get purge bb-cape-overlays
apt-get install bb-cape-overlays
有警告: 警告:缺少/lib/modules/4.9.20-armv7-x4
然后我更新内核:
cd /opt/scripts/tools
git pull
./update_kernel.sh —lts-4_4 —bone-channel
cd /home
git clone https://github.com/beagleboard/bb.org-overlays
cd ./bb.org-overlays
./dtc-overlay.sh
./install.sh
但它不起作用。当我试图回声时控制台冻结。有什么问题?
