sorry for such late response but i was quite consumed with getting mono
winforms running on BBB ...
Thanks for the tips , i learned some new things thanks to them , but the
resolution to HDD was pretty easy , all i had to do was add in my
"/uEnv.txt" file following arguments :
uenvcmd=*usb start;echo Booting from USB ...;*run loadall; run mmcargs;
echo debug: [${bootargs}] ... ; echo debug: [bootz ${loadaddr}
${rdaddr}:${rdsize} ${fdtaddr}] ... ; bootz ${loadaddr} ${rdaddr}:${rdsize}
${fdtaddr};
echo command is not needed but wanted it to be in place for debuging
measures :)
Of course before this i had to format hard drive correctly and change fstab
on it, but it`s described in your guide pretty nicely :)
Thanks again for help !
