Dear All, I bought this LCD monitor able to display at 1280x800@60 (I tested it as external hdmi screen and it worked with 1280x800@60): http://www.amazon.com/Toguard-Monit...&redirect=true&ref_=oh_aui_detailpage_o02_s01 Using U-BOOT I set the env in this way: Code: setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1280x800@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M and then Code: saveenv Nevertheless the Android boots at 640x480@60 regardless the setup. This is what happens at kernel boot: Code: MIPI DSI driver module loaded mxc_sdc_fb mxc_sdc_fb.0: register mxc display driver hdmi mxc_hdmi mxc_hdmi: Detected HDMI controller 0x13:0xa:0xa0:0xc1 imx-ipuv3 imx-ipuv3.0: IPU DMFC DP HIGH RESOLUTION: 1(0,1), 5B(2~5), 5F(6,7) mxc_sdc_fb mxc_sdc_fb.1: Can't get fb option for mxcfb1! mxc_sdc_fb mxc_sdc_fb.2: Can't get fb option for mxcfb2! Any suggestion? -- Raffaele
Hi there, Well, maybe it's missing an "M" specification? Try this: Code: setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1280x800M@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M ek5
Thank you for the answer. Unfortunately doesn't work. These are the messages at boot: Code: mxc_sdc_fb mxc_sdc_fb.0: register mxc display driver hdmi mxc_hdmi mxc_hdmi: Detected HDMI controller 0x13:0xa:0xa0:0xc1 fbcvt: 1280x800@60: CVT Name - 1.024MA imx-ipuv3 imx-ipuv3.0: IPU DMFC DP HIGH RESOLUTION: 1(0,1), 5B(2~5), 5F(6,7) mxc_sdc_fb mxc_sdc_fb.1: Can't get fb option for mxcfb1! mxc_sdc_fb mxc_sdc_fb.2: Can't get fb option for mxcfb2! -- Raffaele edit: please use [ code ] tags for code snippets
Update: I tried with the M specification and even using 1280x720 with no results. Is it possible the resolution is not supported by Android 4.4.2 ? The monitor works perfectly with the UDOO Neo on both Linux and Android 5. Now I'll try the UDOO QUAD with the latest Linux. -- Raffaele
Update: Apparently it is a Android 4.4.2 limitation: using the latest ubuntu by udoo the monitor works perfectly with really remarkable results using the Udoo QUAD. I hope the next Android version for Udoo QUAD (when will be available) will fix the 1280x800 resolution. -- Raffaele
