  1. I2C standard clock are usually 100KHz or 400KHz, but you can try other values. Here is the doc, the parameter is "clock-frequency" : https://www.kernel.org/doc/Documentation/devicetree/bindings/i2c/i2c-designware.txt
  2. Download this UserGuide : http://dl.linux-sunxi.org/A20/A20 User Manual 2013-03-22.pdf Read the LRADC chapter starting at page 192. You will see the description of the ControlRegister at page 193-194. You need your /dev/mem to be "O_RDWR", not "R+" to allow writing into ControlRegister.
  3. Right, but don't forget to initialize Control Register first by setting Continuous Rate and Continuous Mode...
  4. I can do sporadic testing ...
  5. Like the message says, you need to use "-p" : patch -p 1 < 0001-fbtft-fb_ili9488.patch
  6. PWM is always disabled by default in DT. You will need to decompile DTB into DTS, edit the DTS to place ' status = "okay"; ' in the PWM node, and recompile DTS into DTB ...
  7. Overlays on R40 is a bit different than the ones on H3 ... I've done tests on my BPiM2U using proper overlay which is "spi-spidev0" (not "spi-spidev") , without any needs for "param_spidev_spi_bus", and /dev/spidev0.0 appeared properly.
  8. Nope ! All my H6 (OPi3/OPiLite2/OPiOne+) are now on 5.9.y (after a month on 5.8.y), and none have frozen ... But none of them been "upgraded", I'm always do "fresh" install.
  9. Overlays on meson64 are tough and not well supported in Armbian. Even different Amlogic SoCs pinctrl are not compatible between them. I've took a quick look at my OdroidN2, and it seems that GPIOX_7 is pin 72. So, I've created a quick overlay source provided below, although I didn't attached any DS18B20, it seems to work : /dts-v1/; / { compatible = "amlogic,meson-gxbb"; fragment@0 { target-path = [ 2f 00 ]; __overlay__ { onewire@0 { compatible = "w1-gpio"; pinctrl-names = "default"; gpios = < 0xffffffff 0x48 0x06 >; status = "okay";
  10. Ah ! Ok ! So, we can trim my WiFi patches to keep only parts relevant to other drivers not provided by jwrdegoede ...
  11. Those 2 patches worked fine 2 days ago for my 5.9.y builds (and also a month ago in 5.8.y) ... Is there something that changed since then ?
  12. I don't have any objections to merge those subforums ...
  13. My Allwinner garden tour using 5.9.y is almost finished ! Only 2 board models left ...
  14. Those are only the pins. If there isn't something like "spdif@1c21000" node (this one is on H3 SoC), then there is nothing enabled ...
  15. You need to decompile DTB into DTS, edit the DTS to change ' status = "okay"; ' of the spdif-out to ' status = "disabled"; ', and then recompile DTS into DTB.
  16. I think it should be good to switch to u-boot v2020.07, at least for DEV, I've done that since few weeks locally and didn't got any issues ...
  17. Ok ! I will do some 5.9 builds for few of my Allwinner garden members ...
  18. I've an OPi3 currently running 5.8.0 build done almost a month ago ...
