How can I add arch Linux device driver for Zedboard

How can I add arch Linux device driver for Zedboard

Postby vincentlau » Wed Dec 17, 2014 4:56 am

Hi all,
I am working with Zedboard,and it really works fine when I referred to the http://archlinuxarm.org/platforms/armv7/xilinx/zedboard.
However,I have to add FPGA bitstream for Linux drivers.I compiled u-boot via u-boot-digilent-2012.04-digilent-13.01,and renamed u-boot to u-boot.elf,created FPGA bitstream and FBSL( first stage bootloader) via xilinx vivado that I renamed them system.bit and FSBL.elf.And then I created BOOT.BIN based on that three files(u-boot.elf,system.bit,FSBL.elf).Further more,I compiled Linux zImage, devicetree.dtb via linux-digilent.
and then I put BOOT.BIN,zImage,devicetree.dtb to the first partiton of SDcard and put a linaro-precise-ubuntu file system to the second partition,it did work fine.
BUT,when I deleted anything of the second partiton and put ARCH Linux file system to the second partiton,I works failed.
The mistakes are below:
...
[ 1.110000] #0: HDMI monitor
[ 1.150000] fb0: frame buffer device
[ 1.150000] drm: registered panic notifier
[ 1.150000] [drm] Initialized analog_drm 1.0.0 20110530 on minor 0
[ 1.160000] mmc0: new high speed SDHC card at address b368
[ 1.170000] mmcblk0: mmc0:b368 SMI 3.69 GiB
[ 1.180000] mmcblk0: p1 p2
[ 1.180000] EXT4-fs (mmcblk0p2): couldn't mount as ext3 due to feature incompatibilities
[ 1.240000] EXT4-fs (mmcblk0p2): couldn't mount as ext2 due to feature incompatibilities
[ 1.370000] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
[ 1.380000] VFS: Mounted root (ext4 filesystem) on device 179:2.
[ 1.390000] devtmpfs: mounted
[ 1.390000] Freeing init memory: 152K
[ 1.690000] systemd[1]: Failed to mount tmpfs at /sys/fs/cgroup: No such file or directory

I browsed almost all subjects of the forum,but I coudn't find a solution.I really hope you can give me some advice.
Tank you very much!

You are likely missing configuration items in the kernel you built. Check your config against the requirements for systemd:

Tank @pepedog and @kmihelich very much!
I am sorry that I can not find where I can reply you respectively.
----> to pepedog
I have checkd the kernel version:
[root@alarm ~]# uname -r
3.6.0-digilent-13.01-00002-g06b3889-dirty
and I met a new problem!

----> to kmihelich
Tank you again!
I referred to http://cgit.freedesktop.org/systemd/sys ... README#n37
and I have successfully boot arch Linux on Zedboard.
Howerver,I met this problem :
....
Starting udev Kernel Device Manager...
[ OK ] Reached target Local File Systems (Pre).
[ OK ] Started udev Kernel Device Manager.
[ OK ] Found device /dev/ttyPS0.5]: Received request to flush runtime journal from PID 1
[ OK ] Reached target Sound Card.
[ OK ] Started Trigger Flushing of Journal to Persistent Storage.
[ ***] A start job is running for dev-mmcblk0p1.device (23s / 1min 30s)
I have to wait for 1min30s for every reboot.
Should I upgrade Linux kernel ?
