How to change resolution in console mode for TX1 ?

I’m trying to use to change some resolution (640x480) in console mode using jetpack 2.3 for TX1
but, I can’t. However, 640x480 resolution is ok in X11.

The test was conducted as follows.

(1). xrandr --output HDMI-0 -mode 640x480 -> It’s good !!

(2) fbset default -> Kernel Error and unusally fb_match_mode()is returned null.
I got the ‘640x480-60’ value from (1). and saved to /etc/fb.modes using " fbset >> /etc/fb.modes ".

mode "640x480-60"
    # D: 25.200 MHz, H: 31.500 kHz, V: 60.001 Hz
    geometry 640 480 0 0 32
    timings 39721 48 16 33 10 96 2
    rgba 8/0,8/8,8/16,8/24
endmode

  1. use ioctl (FBIOPUT_VSCREENINFO) fuction
struct fb_var_screeninfo vinfo.
     vinfo.xres = 640;
     vinfo.yres = 480;
     vinfo.pixclock = 39721;//  KHZ2PICOS(25200); 
     vinfo.left_margin = 48;
     vinfo.upper_margin = 33;
     vinfo.right_margin = 16;
     vinfo.lower_margin = 10;
     vinfo.hsync_len = 96;
     vinfo.vsync_len = 2;
     vinfo.vmode = 272629760;
     vinfo.sync = 3;
     ioctl(fb_fp, FBIOPUT_VSCREENINFO, &vinfo);

-> there’s error like with test (2).
-> tegradc tegradc.1: pclk out of range!

  1. use ioctl (FBIOPUT_VSCREENINFO) fuction
struct fb_var_screeninfo vinfo.
     vinfo.xres = 1680;
     vinfo.yres = 1050;
     ioctl(fb_fp, FBIOPUT_VSCREENINFO, &vinfo);

-> It’s good

I wonder could I fix the resolution at boot time?

Thanks.

I can verify this causes a kernel panic and leaves the system mostly unusable (some sysrq still works). I probably have a bit more debugging info on this kernel than stock, but otherwise it is the same (R24.2.1). In my case fbset is for “1680x1050-60”, which is the only mode seen by fbset (the monitor supports far more than this).
