Dear list, I am still playing with FreeBSD/Crochet/OrangePi-One. In my last attempts, I was able to boot FreeBSD by using two dtb files: [nano]: NanoPi-Neo ($FREEBSDSRC/sys/boot/fdt/dts/arm/nanopi-neo.dts) [plus]: OrangePi-Plus-2E ($FREEBSDSRC/sys/boot/fdt/dts/arm/orangepi-plus-2e.dts) Using [nano] I was able to use ethernet but not USB. Using [plus] I was able to use USB but not ethernet. Now, I merged [nano] and [plus] generating a dts file for OrangePi One (lets call it: [one]). Basically, [one] is a copy of [plus], but the lines regarding ethernet interface are from [nano]. In particular, lines 65-78 of [plus] are deleted and lines 53-63 of [nano] are used instead. [one] works fine on my OrangePi One, I used it in the last couple of days, and both ethernet and USB are working. --------------------------------------------------------------------------------------------- ==Other attempts: Before writing file [one], I also tried to use the dts file for OrangePi One from Linux: [linux]: $FREEBSDSRC/sys/gnu/dts/arm/sun8i-h3-orangepi-one.dts With this file ethernet does not work, and usb works sporadically. In order to add ethernet, I applyed the patches as described in [1]. To be more specific, I only used the patches written in the following text, copied from the cited blog: #==================================================================== # [v4,04/10] ARM: dts: sun8i-h3: Add dt node for the syscon wget https://patchwork.kernel.org/patch/9365773/raw/ \ -O sun8i-emac-patch-4.patch # [v4,05/10] ARM: dts: sun8i-h3: add sun8i-emac ethernet driver wget https://patchwork.kernel.org/patch/9365757/raw/ \ -O sun8i-emac-patch-5.patch # [v4,07/10] ARM: dts: sun8i: Enable sun8i-emac on the Orange PI One wget https://patchwork.kernel.org/patch/9365767/raw/ \ -O sun8i-emac-patch-7.patch #==================================================================== The resulting patched file ([patch]) boots. I can see both ethernet and USB, but ethernet never works, and USB works sporadically. To be more specific: When I attach an USB memory to the port, I can mount it 1 time over 5 attempts, and when things do not work I see the following messages in dmesg: #==================================================================== ugen0.2: <SanDisk Cruzer Fit> at usbus0 umass0 on uhub0 umass0: <SanDisk Cruzer Fit, class 0/0, rev 2.10/1.00, addr 2> on usbus0 umass0: SCSI over Bulk-Only; quirks = 0x8100 umass0:0:0: Attached to scbus0 (probe0:umass-sim0:0:0:0): INQUIRY.

One of the differences between OrangePi Plus 2E and OrangePi One is the voltage regulator responsible for cpu scaling. I had a look at the values used in the FEX files from Armbian [2] (lines 713-730), and I inserted similar values in the lines 96-97 and 111-121 of [plus]. Things seem to work fine until now, but I really don't know how should I check the correct behavior of cpu-scaling. Moreover, I am not an experienced developer and I am really just putting things together here, so I would like to know if you think I am following the right road. Finally, given that I used a FEX file from Armbian as a reference, and given that I am not sure about the license this file is released with, I do not know what kind of license should I use for my work in progress dts file. I am a beginner here, any kind of help or suggestion is very much appreciated.
