for fbtft_device don't waste your time on that version, switch to
either v4.14.x-ti or v4.16.x-bone

v4.14.x-ti:

sudo /opt/scripts/tools/update_kernel.sh --ti-channel --lts-4_14

v4.16.x-bone:

sudo /opt/scripts/tools/update_kernel.sh --bone-channel --exp

Robert what William said makes sense but i have no idea where to look to
disable the debug mode on that loadable mod.
I have a cross compile environment and i see that in your build you do
compile them.
any help would be awesome

Apparently, the driver was compiled with debug symbols, and in debug mode.

[beagleboard] display driver

2018-02-22 Thread evilwulfie 
The more i learn the more i don't know

Got most everything working with a spi display but one last issue i cant
seem to figure out.

if i load the module

modprobe -v fbtft_device busnum=1 cs=0 speed=1600 name=er_tftm070_5
gpios=reset:60,dc:24,led:50

it loads with no errors

i can display a jpg on the monitor

fbi -noverbose -T 1 -a -d /dev/fb0 Mystery-100x100.jpg

it displays the image on display just fine proving that the module is
functioning fine

ok this is good i say but if i tail -f /var/log/messages OR view dmesg 
OR tail -f /var/log/syslog

it spams the below messages over and over.  If i read the logs it inits
the display fine but the repeating messages baffle me.

when i modprobe -r fbtft_device

the errors go away

I am SO over my head in kernel land i just need a little help here if
anybody knows what might be going on.
