I have run into an RCU stall when booting openwrt on my ClearFog CN9130 Pro. In my recent past this problem was solved by using the right dts file. I have tried to use a dts file from upstream linux but that wasn’t working for me.
Are there patches needed to the dts file in order to boot openwrt on CN9130-Pro ?
We are working on an OpenWRT patchset. It will be published soon.
I am happy to do some testing if that is needed. Please reply here if I can assist.
@jnettlet Any updates? I see in github repo there are some device tree patches. Would putting all those patches into an openwrt.org device tree file be a worthwhile test? Or is there more behind the scenes work ?
@jnettlet , I pulled the device tree file from the ubuntu image that solid run posted on images.solid-run.com. Applied it to the build tree for openwrt and the board comes up and seems to be working well. I am wondering if you can post or link to the original device tree file as the decompiled file is not suitable for inclusion upstream. I am happy to slog to get it upstreamed, but I have to have a decent file to begin with.
Happy to answer any questions.
is there anything new for an official .defconfig?
@jnettlet I have submitted the device tree files for the CN9130 to the mailing lists here is the link to the message. I have you on cc per a previous comment on this forum. I hope I haven’t mailed out of turn and wish to assist as needed.
Thanks for the community support. I will keep an eye on the list and if there are any issues I will chime in.
@jnettlet,
I aligned the dts file to the kernel conventions, change _ to - , added a compatible line, etc. But there are some issues that I am out of my depth on wrt a dts file and the hardware it describes. Are you able to tell me what the “right” name is for ap0_reg_sd_vccq: ap0_sd_vccq@0 and the incorrect property problems that Krzysztof is mentioning in his reply?
do you have your updated dts patches somewhere that I can review them?

Hi lblyth,
I am testing this on my CN9130 Clearfog Pro, with your dts and Makefile patch included in the 6.2.8 kernel source. Seems to be working pretty well thus far. I did get one strange line in dmesg:
[ 6.530664] mv88e6085 f212a200.mdio-mii:04: OF node /cp0/config-space@f2000000/mdio@12a200/switch@4/ports/port@5 of CPU port 5 lacks the required “phy-mode” property
Adding the following before line 296 seems to resolve the problem:
phy-mode = “sgmii”;

@solarnetone ,
thank you for the update. Odd that is required cause that info is elsewhere in the dts file linked by that name. But that means I still have more to learn 
Also was that a kernel.org kernel? or were you inside of openwrt / yocto?
@jnettlet Any edits?
Booting debian with 6.2.8 and the device trees works on base and pro, but the link loss problem with 10G fiber optics still remains:
Hi @bareminimum ,
I have my CF9130 Pro connected directly to a Honeycomb. I am seeing no such problems using these optics configured for Nvidia firmware:
I have yet to see a disconnect with this configuration.
In SFP Optics module debugging - #5 by bareminimum I posted a table of some combinations we tried so far. Click on Summary to view it.
I’ll try and hook it up the Honeycomb some time the next 2 weeks.
What OS are you running on your Honeycomb and how do you boot it?
I saw your table, which is where I learned to try the Nvidia (ex Mellanox) optics setting.
It is a custom in-house Debian derivative, also running a 6.2.8 kernel.org kernel. I boot from SD card using the provided Solid-Run image. The root filesystem is fully encrypted, on NVME. I modified /extlinux/extlinux.conf on the SD card’s filesystem, in addition to placing my custom kernel/dtb in /boot there. No initrd is required. The SD card can be removed after boot. In this fashion, restool had to be compiled from source, and a few errors therein fixed, before being able to use the SFP+ cages on the Honeycomb.
@jnettlet ,
I was wondering about this part of the dts file:
expander0: gpio-expander@20 {
/*
* This is how it should be:
* compatible = "onnn,pca9655", "nxp,pca9555";
* but you can't do this because of the way I2C works.
*/
compatible = "nxp,pca9555";
I think I see that the SFP cages go through this expander, does this section of the dts file need to change in order to reflect that?
quick edit to post this, hopefully it is useful:
