  1. I am trying to connect a PPS source to an ODROID-C2 board using GPIO. I am running Armbian 19.11.3 Buster, with kernel 5.3.11-meson64. I downloaded the Armbian kernel source for this kernel, added the following to meson-gxbb-odroidc2.dts, and compiled and installed it: pps { compatible = "pps-gpio"; gpios = <&gpio GPIOY_3 GPIO_ACTIVE_HIGH>; status = "okay"; interrupt-parent = <&gpio_intc>; interrupts = <26 IRQ_TYPE_LEVEL_LOW>; }; When I boot and load the pps-gpio module, I get the following error: pps-gpio pps: failed to map GPIO to IRQ: -6 pps-gpio: probe of pps failed with error -22 Could anyone help me understand what I'm getting wrong that's causing this error? Am I misunderstanding how to assign IRQs to GPIOs?
  2. Hi, balbes150, I can get the 4.14.11 and 4.17.0-rc2-next images to boot using the p201 dtb. When I do so, although the kernel detects the ethernet PHY and its state correctly, when I configure eth0 with an IP address, it still can't actually talk with the network. This works fine with the 3.14 kernel. Do you have any suggestions about how I can debug this?
  3. Hi, balbes150, I have a S905 tv box that came stock with Android 6.x. There does not appear to be an Android 7.x build available from the vendor. This appears to be a common issue for S905 (non-X/W/etc.) boxes. Is there a way to either build a 4.9 or newer kernel that the existing u-boot can boot, a way to build a chain u-boot, or some other solution to get the newer kernels on these boxes? My box boots your 3.14 kernel using one of the generic S905 DTBs. Is it possible/likely that we can get to a set of similarly generic S905 dtbs for 4.9 or newer? It looks like there are no S905 dtbs in your build at all. Many thanks for all of your work getting the S905 series working.
