  1. LVDS Framebuffer hummingboard Kernel 4.13

    Thanks, I did, with above result. If the driver would not work for the solo i expect to see a message when the the driver is probed. It seems that no attempt is made to load the driver.
  2. LVDS Framebuffer hummingboard Kernel 4.13

    I have trouble getting the driver (imx-ldb) to load. It is present in the kernel, but there is no sign of it in dmesg. Also no fb. In my dtb: // ldb: ldb { The address was missing in the original dtsi , needed? ldb: ldb@020e0008 { #address-cells = <1>; #size-cells = <0>; compatible = "fsl,imx6q-ldb", "fsl,imx53-ldb"; The driver is imx6q Works for Solo ? gpr = <&gpr>; status = "okay"; lvds-channel@0 { #address-cells = <1>; #size-cells = <0>; reg = <0>; status = "okay"; port@0 { reg = <0>; lvds0_mux_0: endpoint { remote-endpoint = <&ipu1_di0_lvds0>; }; }; port@1 { reg = <1>; lvds0_mux_1: endpoint { // remote-endpoint = <&ipu1_di1_lvds0>; remote_endpoint = <&panel_in>; }; }; }; panel { // klp compatible = "mitsubishi,aa121td01", "panel-lvds"; width-mm = <261>; height-mm = <163>; data-mapping = "jeida-24"; panel-timing { clock-frequency = <60000000>; hactive = <1024>; vactive = <600>; hback-porch = <160>; hfront-porch = <160>; vback-porch = <23>; vfront-porch = <12>; hsync-len = <70>; // 60 vsync-len = <15>;// 10 // <1>: high active // <0>: low active hsync-active = <1>;//hsync pulse is active low/high/ignored vsync-active = <1>;//vsync pulse is active low/high/ignored // de-active = <1>; pixelclk-active = <1>;// active high = drive pixel data on rising edge/sample data on falling edge // active low = drive pixel data on falling edge/ sample data on rising edge }; port { panel_in: endpoint { remote-endpoint = <&lvds_out>; }; }; }; Any idea?
  3. LVDS Framebuffer hummingboard Kernel 4.13

    Hi, thanks for the quick reply. I was digging in the source and found the DRM stuff. I have compiled this into the kernel. Still no fb. Have to adapt the dtb. Is nobody using the LVDS on the solo module? Dig
  4. Hi I moved from 3.14 to 4.13. In 3.14 I had a imx framebuffer , needed for my lvds LCD In the 4.13 kernel menuconfig i cannot find a way to set CONFIG_FB_IMX. How to enable this? Dig
