[opensuse-arm] Is there any good way to specify frame buffer size options to Raspi2 kernel?
Hi, Is there any good way to specify framebuffer options to Raspberry Pi 2 kernel? To set the size of frame buffer, we need to specify the size options by kernel cmdline. (Otherwise the resolution of framebuffer will be 800x480) - bcm2708_fb.fbwidth - bcm2708_fb.fbheight - bcm2708_fb.fbdepth - bcm2708_fb.fbswap I now specify those options by modifying boot.script. It seems that on Rasbian, u-boot passes the size options to kernel according to "display_mode". However, on openSUSE, it does not. Is it possible passing those options in the same way as Rasbian? Or any better way to add some options to kernel cmdline?

Fuminobu thanks for posting this, I have same problem myself. Can you explain how you are setting this i set bcm2708_fb.fbwidth=1280 and bcm2708_fb.fbheight=1024 in bootargs and rebooted, but nothing changed, im still in 800x480, I am very likely doing something wrong here, can you show me exactly what you are doing? thanks and hopefully someone has a better more automatic solution for the future. - Michael Emory Cerquoni -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
Hi Michael, Did you make a new boot.scr from your modified boot.script? You need to run mkimage every time when you update boot.script. $ mkimage -C none -A arm -T script -d boot.script boot.scr Fuminobu TAKEYAMA, On 2016/03/27 3:26, Michael Emory Cerquoni wrote:

that was it, i now have it working in 1280x1024!! Thank you so much this is a big step forward for sure, hopefully this gives someone with more knowledge of how to fix this the ability to do so now! I feel like I can actually start using tumbleweed on my raspberry pi2 now!! thanks so much! On Sun, Mar 27, 2016 at 10:34 AM, Fuminobu TAKEYAMA <ftake@geeko.jp> wrote:

$ mkimage -C none -A arm -T script -d boot.script boot.scr

Here is screenshot of my LXDE Desktop running in 1280x1024 on latest tumbleweed pi2 image! Thanks again! http://nebadon2025.com/pi2/tumbleweed_raspberrypi2_framebuffer_fix_01.png On Sun, Mar 27, 2016 at 10:34 AM, Fuminobu TAKEYAMA <ftake@geeko.jp> wrote:
