different commandline, no ubi attach probably.
I booted a letux-4.16.0-rc2 and there I could read out things using the
string commands. 
So there is a onenand problem here too, but it is nicer if the kernel
at least boots. So maybe let's first get the string commands working
again.

root at gta04:~# cat /proc/cmdline 
root=/dev/mmcblk0p6 rootfstype=ext4,ext3,btrfs rootwait twl4030_charger.allow_usb=y mpurate=800 console=ttyO2,115200n8 vram=12M omapfb.vram=0:8M,1:4M omapfb.rotate_type=0 omapdss.def_disp=lcd rootwait twl4030_charger.allow_usb=1 log_buf_len=8M ignore_loglevel earlyprintk

Andreas
