Hey, I've been working a good bit with the mini2440 but was wondering if anyone solved this one. I've got Friendlyarm's kernel (2.6.32.2) with a minimal fs built using OE. I've been wondering about two things: 1. In the migration from 2.6.29.x to 2.6.32.2 the font seems to have gotten bigger, can anyone shed some light? Is the font a kernel setting? 2. The screen powers down after a couple of minutes of no use and I can't get it to power back on again (no suprise since I'm controlling it via ethernet or seria), does anyone know how to disable this? Power management is disabled in my kernel build. Thanks a lot Pajolo
Mini2440 Screen Font Size & Power
Update: if I plug a usb keyboard into the mini2440 and type the screen comes on again, so it's definitely a power management thing. Any ideas on how to kill it? Thanks
Hey dm9, can't write to /blank or any other of the files in that folder... I ve chmodded them, tried overwriting, cat, vi, but nothing. I'm pretty sure they're in use. Any ideas? Thanks
The keywords is "setterm", please check the FriendlyARM's default Linux -> etc -> init.d -> RCA, maybe at the last line.
Thanks, but I m using OE and there's no such command. Is there any way I can set the values manually? Thanks Paul
this: ========================= #echo "0" > /sys/devices/platform/s3c2410-lcd/graphics/fb0/blank ========================= works with me, just to unblanking the screen, and screen will blank again next 10 minutes. what i did is, i read this file, ========================= #cat /sys/module/kernel/parameters/consoleblank 600 ========================= wala.. there is where 10 minutes came from from this page, http://fxr.watson.org/fxr/source/Documentation/kernel-parameters.txt?v=l... then i add consoleblank=0 to my "bootargs" variable in u-boot this is my NEW bootargs variable value bootargs=root=/dev/mtdblock3 rootfstype=jffs2 console=ttySAC0,115200 consoleblank=0 mini2440=1tb this is how i did it; i type this at u-boot shell-like ========================= setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttySAC0,115200 consoleblank=0 mini2440=1tb saveenv reset ========================= after reboot, i read this file again and got 0 ========================= #cat /sys/module/kernel/parameters/consoleblank 0 ========================= GUTLAK GAN (^_^)7

When I start my board there is the kernel logo (the tux penguin). Then if I let the screen shut down after 10 minutes, and power-on the screen again by typing something on my usb-keyboard/press one of the six buttons on the board, the kernel logo isn't shown anymore. There is just a black empty space as big as the kernellogo was, but no logo. If I keep the display on all the time by typing on the usb-keyboard, the logo will off course stay there. So is it in any way possible to do so that the kernel logo would be visible also when the display is powered on again?
Ideas, anyone? I think the problem that the tux logo goes away, is that the system will blank the console after 600 sec, with: echo "1" > /sys/devices/platform/s3c2410-lcd/graphics/fb0/blank That 600 seconds time is set up in /sys/module/kernel/parameters/consoleblank Here is some more info: http://friendlyarm.net/forum/topic/1133 So if I could shut down the screen after those 600 sec in some other way than blanking, I think the logo would still be there. I wouldn't like to have the screen constantly on as I think it won't last forever, and draws too much power.
