tantal

Hi There, I would like to run Linux5 or Linux6 on Jetson nano, display using HDMI-DVI adapter. It worked fine with Jetpack4 (=Linux4). When I boot with armbian/Linux5.10, which is linux-image-current-jetson-nano, the display tells me it is out of sync then I would force the display as 1280x1024@60Hz, since it looks like Linux fb or X11 are trying to use 1280x1024@75Hz, so that I need edid/1280x1024.bin (maybe with video=1280x1024@60) using {linux-source}/tools/edid to maintain the resolution and sync. I tried both of gcc-10 and gcc-9 to build it, but failed with below error: edid.S: Assembler messages: edid.S:274: Error: cannot represent BFD_RELOC_8 relocation in this object file format Any workaround? or is this plan never work? Thank you.

I could solved by myself. I specified wrong gpio number therefore no activities. Now I see the device connected to spi-gpio is working. Thank you.

Neo has one SPI port and I need two, so would like to add another spi using spi-gpio, but no success (I think). I am using Armbian 23.02.2 Bullseye, default kernel does not enable it, recompiled using linux-source-5.15.93-sunxi.tar.xz, enabled spi-gpio as module. Digged around forum, prepared below dts and armbian-add-overlay succeeded. But there is no message arrived when loading (dmesg shows nothing about spi) and no /dev/spi* created. Is it OK or there must be something? Please advise.... / { compatible = "allwinner,sun8i-h3"; fragment@0 { target-path = "/"; __overlay__ { softspi: spi_gpio { compatible = "spi-gpio"; #address-cells = <1>; #size-cells = <0>; ranges; sck-gpios = <&pio 0 15 0>; /* PG6 */ mosi-gpios = <&pio 0 16 0>; /* PG7 */ miso-gpios = <&pio 0 1 0>; /* PA6 */ num-chipselects = <0>; status = "okay"; spidev { compatible = "linux,spidev"; reg = <0>; spi-max-frequency = <10000000>; status = "okay"; }; }; }; }; };
