Hi everyone, I want to enable SPI0 on beaglebone black, and I've been following resources online:
http://embedded-basics.blogspot.com/2014/10/enabling-spi0-on-beaglebone-black.html http://elinux.org/BeagleBone_Black_Enable_SPIDEV after changing uEnv.txt and rebooting bbb however, bbb doesn't come back online. All 4 of the usr LEDs are on, and I can no longer connect back to beaglebone. Firstly, a few clarifications, in My Computer > BeagleBone Getting Started, I did not find any uEnv.txt file, but nfs-uEnv.txt. The contents of nfs-uEnv.txt are: ##Rename as: uEnv.txt to boot via nfs > ##https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt > ##SERVER: sudo apt-get install tftpd-hpa > ##SERVER: TFTP_DIRECTORY defined in /etc/default/tftpd-hpa > ##SERVER: zImage/*.dtb need to be located here: > ##SERVER: TFTP_DIRECTORY/zImage > ##SERVER: TFTP_DIRECTORY/dtbs/*.dtb > ##client_ip needs to be set for u-boot to try booting via nfs > client_ip=192.168.1.101 > #u-boot defaults: uncomment and override where needed > #server_ip=192.168.1.100 > #gw_ip=192.168.1.1 > #netmask=255.255.255.0 > #hostname= > #device=eth0 > #autoconf=off > #root_dir=/home/userid/targetNFS > #nfs_options=,vers=3 > #nfsrootfstype=ext4 rootwait fixrtc > In the embedded-linux blog, he suggested to delete everything in the file and put in optargs=quiet drm.debug=7 capemgr.enable_partno=BB-SPI0-01 > > I however followed the instructions from elinux, and just copied the the above line. After that, I changed the name of the file from nfs-uEnv.txt to just uEnv.txt and rebooted bbb by typing reboot on the terminal, and now I don't think bbb works. Any ideas on what I'm doing wrong?
