Recently I was trying to run a Linaro on my zed board, following the steps of “LINUX WITH HDMI VIDEO OUTPUT ON THE ZED AND ZC702 BOARDS”. After all things had been done, the Linaro started with errors and the HMDI video stopped at a sense of twinkle cursor.
These are my operating steps and the boot information. I wonder if there was anything wrong in my operations.
- Git u-boot from Xilinx, configure it with zynq_zed_config and create boot.elf. Use cf_adv7511_zed reference design to build BOOT.bin.
- Download the Linux kernel; switch it to xcomm_zynq branch and configure it with zync_xcomm_adv7511_defconfig. Build zImage and zynq-zed-adv7511.dtb.
- Download rootfs file and extract it to SD card.
The main errors :
init: Failed to create pty - disabling logging for job
init: Temporary process spawn error: No such file or directory
Failed to create pty - disabling logging for jobr job
modprobe: FATAL: Could not load /lib/modules/3.3.0-01876-gff09395/modules.dep: No such file or directory
mmcblk0: error -110 transferring data, sector 318400, nr 24, cmd response 0x900, card status 0xc00
end_request: I/O error, dev mmcblk0, sector 318401
Buffer I/O error on device mmcblk0p2, logical block 26744
EXT4-fs error (device mmcblk0p2): ext4_journal_start_sb:327: Detected aborted journal
mmcblk0: error -110 transferring data, sector 104448, nr 8, cmd response 0x900, card status 0xc00
The attached file is the complete information of booting. It seems that there is something wrong with the ext4 fs and I/O buffer.
