Hi, I have created Images for Beagle bone black, and Board bring up was successful via sdcard.
But when I tried to mount the rootfs using nfs , i’m getitng kernel panic. Log: *[ 1.939870] VFS: Cannot open root device "nfs" or unknown-block(0,255): error -6* *[ 1.947781] Please append a correct "root=" boot option; here are the available partitions:* *[ 1.956773] 0100 16384 ram0 [ 1.960523] (driver?)* *[ 1.963071] 0101 16384 ram1 [ 1.966814] (driver?)* *[ 1.969300] 0102 16384 ram2 [ 1.973107] (driver?)* *[ 1.975599] 0103 16384 ram3 [ 1.979340] (driver?)* *[ 1.981859] 0104 16384 ram4 [ 1.985603] (driver?)* *[ 1.988087] 0105 16384 ram5 [ 1.991858] (driver?)* *[ 1.994345] 0106 16384 ram6 [ 1.998087] (driver?)* *[ 2.000570] 0107 16384 ram7 [ 2.004342] (driver?)* *[ 2.006829] 0108 16384 ram8 [ 2.010570] (driver?)* *[ 2.013084] 0109 16384 ram9 [ 2.016827] (driver?)* *[ 2.019311] 010a 16384 ram10 [ 2.023171] (driver?)* *[ 2.025658] 010b 16384 ram11 [ 2.029491] (driver?)* *[ 2.032004] 010c 16384 ram12 [ 2.035838] (driver?)* *[ 2.038322] 010d 16384 ram13 [ 2.042188] (driver?)* *[ 2.044675] 010e 16384 ram14 [ 2.048508] (driver?)* *[ 2.050992] 010f 16384 ram15 [ 2.054853] (driver?)* *[ 2.057357] b300 7761920 mmcblk0 [ 2.061402] driver: mmcblk* *[ 2.064342] b301 512000 mmcblk0p1 7f863e1e-01[ 2.069721] * *[ 2.071322] b302 7248896 mmcblk0p2 7f863e1e-02[ 2.076701] * *[ 2.078278] b308 3735552 mmcblk1 [ 2.082327] driver: mmcblk* *[ 2.085266] b309 3731456 mmcblk1p1 ca48043c-01[ 2.090645] * *[ 2.092251] b318 2048 mmcblk1boot1 [ 2.096722] (driver?)* *[ 2.099207] b310 2048 mmcblk1boot0 [ 2.103703] (driver?)* *[ 2.106189] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,255).* ->My Host system is running on Archlinux. ->I belive I have selected proper nfs support in menuconfig: <*> kmod-fs-nfs................................
