  1. @Wener thanks for the guidance. It seems that fdtfile= in armbianEnv.txt doesn't work. Incidentally, i saw both lite2 and one+ dtb in /boot/dtb/allwinner folder and i just need to switch dtb name because apparently the image file is hardcoded to load the respective board name.
  2. Yes, because I want to maintain 1 image for 2 boards.
  3. Hi I would like to know whether I can use orange pi lite 2 image on orange pi one plus. I tried it but eth0 is not visible. Is there a way to tweak it? The reason is I want to create an image with various packages installed. So that i do not need to maintain 2 sd images since both are H6. Tq
  4. I have not tried it though because it is not documented in /boot/overlays/READMExxx for SPI
  5. There is no deny that SCK has extrac burst before data is transferred. Further investigation confirms that it happens right before the edge of CE0 (in my case active low). If you use the kernel to control CE0, then you are safe. However, if you use a manual way to control CE0 (like me), then you will have problem due to slave may mistakenly interprete the burst as a clock and read in a wrong info. I am not sure whether i consider luckily, the kernel generated CE0 is active low (by default?). If you need an active-high CE0, may be someone can share some thought on how to achieve this. Cheers
  6. Hi, I moved from Jessie to Stretch. On Jessie i looked under a scope and generated SCK (Orange Pi Lite is Master) is clean. However, after i switch to Stretch, my SPI Slave doesn't work anymore and further investigation reviews that it has similar problem as previous builds that extra clock cycle is generated before data is transfered. The behaviour is exactly similar to following image posted by another forumer but for earlier builds. I am not sure whether any of you experience the same problem.
