I've been trying without success to start an ADAS board by booting and loading the rootfs from NFS or from MMC. What I've done: * Build the kernel and the toolchain was given here: http://elinux.org/R-Car/Boards/Yocto#Building_the_BSP_for_Renesas_R-Car_SILK.2C_Porter_and_Stout * Set up the parameters in multiple ways: ** using the mkBootargsNFS or mkBootargsMMC already pre-set in the boards u-boot environment ** using the lines from here: http://elinux.org/R-Car/Boards/Yocto190#For_Porter_board The result is always the same, the kernel boots but doesn't find the device: for MMC I get 'VFS: Cannot open root device "mmcblk0p1" or unknown-block(0,0): error -6 ' for NFS I get ' VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6 Please append a correct "root=" boot option ' This happens although: * the nfs server is up and running properly (tested with a Lager board) * the MMC device is present and clean, the kernel is actually loaded from the sdcard - see the logs below Any ideas, why this happens? The logs for the two use cases are below. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- A typical log for NFS: = = printenv _ip=ip=10.96.21.32:10.96.22.71::255.255.255.0::eth0 _kaddr=0x40007fc0 _mem=vmalloc=386M _mmcKernelDir=/boot/uImage+dtb _mmcblk=/dev/mmcblk0p1 _mmcload=ext4load mmc 0:1 _nfsdir=/opt/poky.stout/rootfs _rootNFS=root=/dev/nfs rw nfsroot=10.96.22.71:/opt/poky.stout/rootfs rootwait _tftpKernelDir=rcar2/stout/uImage+dtb _tty=console=ttySC0,38400 _video=video=HDMI-A-1:1024x768-32@60 baudrate=38400 bootMMC=run mkBootargsMMC; run mkBootcmdMMC; run bootcmd bootNET=run mkBootargsNFS; run mkBootcmdTFTP; run bootcmd bootargs=console=ttySC0,38400 video=HDMI-A-1:1024x768-32@60 vmalloc=386M ip=10.96.21.32:10.96.22.71::255.255.255.0::eth0 root=/dev/nfs rw nfsroot=10.96.22.71:/opt/poky.stout/rootfs rootwait bootcmd=tftp 0x40007fc0 rcar2/stout/uImage; tftp 0x40f00000 rcar2/stout/uImage-r8a7790-stout.dtb; bootm 0x40007fc0 - 0x40f00000 bootdelay=3 bootm_low=0x40e00000 bootm_size=0x100000 ethact=sh_eth ethaddr=00:11:22:33:44:55 fileaddr=40F00000 filesize=952A gatewayip=10.96.20.1 ipaddr=10.96.21.32 mkBootargsMMC=run mkRootMMC; run mkIP; setenv bootargs ${_tty} ${_video} ${_mem} ${_ip} ${_rootMMC} mkBootargsNFS=run mkRootNFS; run mkIP; setenv bootargs ${_tty} ${_video} ${_mem} ${_ip} ${_rootNFS} mkBootcmdMMC=setenv bootcmd ${_mmcload} ${_kaddr} ${_mmcKernelDir}\\; bootm ${_kaddr} mkBootcmdTFTP=setenv bootcmd tftp ${_kaddr} ${_tftpKernelDir}\\; bootm ${_kaddr} mkIP=setenv _ip ip=${ipaddr}:${serverip}::${netmask}::eth0 mkRootMMC=setenv _rootMMC root=${_mmcblk} rw rootwait mkRootNFS=setenv _rootNFS root=/dev/nfs rw nfsroot=${serverip}:${_nfsdir} rootwait netmask=255.255.255.0 serverip=10.96.22.71 stderr=serial stdin=serial stdout=serial ver=U-Boot 2013.01.01-gcb82c56-dirty (Aug 10 2015 - 15:20:25) Environment size: 1777/262140 bytes = saveenv Saving Environment to SPI Flash...
