how to give rootfs address to kernel.
Hi,
Iam using IMX6Q board with Yocto Project.Iam having a requirement of modifying the kernel(appending some data to the kernel)after modifying the kernel while booting its hanging after showing following lines. mmc2: new high speed SDHC card at address e624 mmcblk2: mmc2:e624 SU08G 7.40 GiB mxc_vdoa 21e4000.vdoa: i.MX Video Data Order Adapter(VDOA) driver probed mmcblk2: p1 p2 mxc_hdmi_cec soc:hdmi_cec@00120000: HDMI CEC initialized we are suspecting that kernel is not able to find the location of rootfs.if so please help me how to solve this problem. thanks in advance. sunilkattubadi. |
Use the correct boot parameters?
My Raspberry PI show with dmesg "Kernel command line: dma.dmachans=0x7f35 bcm2708_fb.fbwidth=656 bcm2708_fb.fbheight=416 bcm2708.boardrev=0xe bcm2708.serial=0x4d5d1cfa smsc95xx.macaddr=abcdefghijklmnop bcm2708_fb.fbswap=1 bcm2708.uart_clock=3000000 vc_mem.mem_base=0x1ec00000 vc_mem.mem_size=0x20000000 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait". This is with raspian. So, depending of your kernel, identify and use the correct boot parameter. This is just my thought this morning. Perhaps it helps. |
