  1. Support of Raspberry Pi

    Earlier in the current thread :
  2. Icenowy had submit several patches for H6 on liunux-sunxi ML, so I presume we will benefit from those sooner or later...
  3. SH1106 128x64 (SSD1306) I2C oled display library

    This wiring seems Ok ! But what did you do after ? Did you have loaded the sun8i-h3-i2c0.dtbo overlay ? Did you wrote some software, either in python or other language, to initialize the OLED properly and write some pixels into it ? Because, unless doing so, don't expect the kernel itself to display anything there ...
  4. SC16IS752 UART on opi-zero

    Did you tried to add the stuff in the main dtb (of course, after doing a backup) ?
  5. SC16IS752 UART on opi-zero

    Where this comes from ? It's probably that i2c overlays isn't loaded before your overlay ?
  6. SH1106 128x64 (SSD1306) I2C oled display library

    This OLED LCD is I2C based. So you need to hookup the SDA and SCK to your board.
  7. Which dtb is loaded?

    Try also to set clock-frequency = <0x61a80>, since 200KHz is a non-standard value, maybe any value between 100KHz and 400KHz will fallback to 100KHz.
  8. Is armbian for H5 cpu 64 bit os?

    Of course ! But why asking that in H2/H3 sub-forum ?
  9. armbianEnv.txt

    Ok ! I was asking because I don't own any cubietruck, and on almost all boards I own, the u-boot version is now 2017.11.
  10. armbianEnv.txt

    It looks like you are using an old u-boot from Sept 2016. Is this a system that you've upgraded only the kernel without upgrading the u-boot ?
  11. Boot your OPiPC+ using a SDCard, and after completing the "first boot" steps, then simply use the command "nand-sata-install" ...
  12. disable UART0 on OPI-Zero

    I guess I will have to try myself when I will have a chance... But "time is the missing ingredient" In the mean time,you should probably continue googling the u-boot forums/mailinglist.
  13. disable UART0 on OPI-Zero

    Although I didn't try it myself, I presume by appending it to the previous patch as follow : --- a/configs/orangepi_zero_defconfig +++ b/configs/orangepi_zero_defconfig @@ -15,3 +15,5 @@ CONFIG_SPL_SPI_SUNXI=y CONFIG_SUN8I_EMAC=y CONFIG_USB_EHCI_HCD=y CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE=y +CONFIG_SILENT_CONSOLE=y +CONFIG_EXTRA_ENV_SETTINGS="silent=1\0"
  14. Did you tried different TVs ? VSync could be defective on the one you've tested ...
  15. Difficulty accessing gpio via sysfs interface

    Be aware that pin numbering mentioned in Igor's link is important for all AllWinder SoC. This mean that the gpio11 you've tried is actually PA11, and beware also that pins can have multiple usages, and here PA11 could be TWI0_SCK if you have loaded I2C mainline overlay or having I2C enabled in legacy FEX.
