  1. Hi to enable mmc try this
  2. @felipeduque The audio that I mentioned is on h3, i tested sound and mic and work.
  3. Try this
  4. Hi marco, i use this file on debian xenial, i dont have any idea why this file dont on on debian strech. Please download xenial version an copu the device tree file when i descrybe.
  5. Hi Marco, The is necessary run only once to fixed mac address number.
  6. The nano pi core armbian image not have ethernet support I made the file with little modification to fix this.
  7. Hi the solution you found here
  8. I'm trying to learn a little more about uboot and device tree, I already managed to create my own boot.scr, but I'm not having any success with device tree overlay, especially when typing the command. fdt apply ${load_addr} before I can type all these commands successfully setenv kernel "zImage" setenv ramdisk "uInitrd" setenv fdtfile "sun8i-h3-nanopi-neo-core.dtb" setenv load_addr "0x44000000" setenv rootdev "/dev/mmcblk0p1" setenv verbosity "1" setenv console "both" setenv disp_mem_reserves "off" setenv rootfstype "ext4" setenv consoleargs "console=ttyS0,115200" setenv uuid "UUID=7ac33e6e-fa92-4fd2-bb7c-bde01b119803" setenv rootfstype "ext4" part uuid mmc 0:1 partuuid load mmc 0 ${kernel_addr_r} /boot/${kernel} load mmc 0 ${ramdisk_addr_r} /boot/${ramdisk} load mmc 0 ${fdt_addr_r} /boot/${fdtfile} fdt addr ${fdt_addr_r} fdt resize load mmc 0 ${load_addr} /boot/dtb/sun8i-h3-w1-gpio.dtbo here is the error screen where nothing happens
  9. After compile my own kernel a have same problem above. Anyone help me ? I try use nano pi core, now after build kernel with the changes in DTS i have network and mmc working together, but when startup i have the same problem above I put modules in /lib/modules/4.16.0-rc1 but noting change
  10. Hello. I am trying read to directly access GPIO PL11 (IRTX) from nano Pi DUO without success, other pins with this same code work very well. Via Userspace work well echo "363" > /sys/class/gpio/export echo "in" > /sys/class/gpio/gpio363/direction cat /sys/class/gpio/gpio363/value Then i receive 0 or 1 (This proves that hardware is ok.) My example code To compile gcc gpio_lib.c simple_gpio.c -o blink #include <stdlib.h> #include <stdio.h> #include "gpio_lib.h" int main() { sunxi_gpio_init(); //gpio_PA3 sunxi_gpio_set_cfgpin(SUNXI_GPA(4), SUNXI_GPIO_OUTPUT); sunxi_gpio_set_cfgpin(SUNXI_GPL(11), SUNXI_GPIO_INPUT); while(1) { unsigned int b = sunxi_gpio_input(SUNXI_GPL(11)); printf("%x\n", b); sunxi_gpio_output(SUNXI_GPA(4), 1); sleep(1); sunxi_gpio_output(SUNXI_GPA(4), 0); sleep(1); } return 0; } gpio_lib.c gpio_lib.h simple_gpio.c
  11. Hi guys some news about an armbian compilation for this board.
  12. My little contribution for the community Node.js 4 GPIO control for h3 processors.
