missing .dts file for firefly rk3288 reload board

[bschiett]

I compiled the kernel using branch release-20160920, hoping to use it with my
firefly rk3288 reload board (see http://en.t-firefly.com/en/firenow/firefly_rk3288/).

I configured the kernel with rockchip_linux_defconfig and I'm using rk3288-firefly.dts. I managed to boot with the kernel but it seems that the hardware on my firefly reload board doesn't work. I can see graphics via HDMI and see the linux desktop but when I plug in a mouse it doesn't work, probably because the .dts file for my reload board has to be different from the original .dts for the firefly board.

Also, I get the below kernel messages on the serial console endlessly looping, I suppose this has to do with the .dts file not being correct for my board. See below for the kernel messages on the serial console which are looping non stop.

I know that firefly has a kernel config and dts file for the reload board in their kernel repository. I thought I could copy their .dts and kernel config to use it with the above branch of rockchip's kernel but I'm not sure how to do it. Is it a matter of putting their kernel config in ./arch/arm/configs/ and .dts file in ./arch/arm/boot/dts/ and i can automatically use it or is there something else I should do? I would appreciate it if the kernel config/dts file for the reload board are added to rockchip's kernel repo.

I can also add that in the mainline there is no kernel config for rockchip but there is a .dts file for the reload board, see

https://github.com/torvalds/linux/tree/master/arch/arm/configs
https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/rk3288-firefly-reload.dts

[hizukiayaka]

Yes, it is what I submitted to mainline. For the firefly rk3288 reload, I would suggest you to use the mainline kernel.
You may not use the firefly release dts for firefly reload, the hardware connection is a little different.

[bschiett]

@hizukiayaka thanks, yesterday I checked out mainline stable tag 4.8.1 (latest) and then noticed your rk3288-firefly-reload.dts is not in it yet, so I went to download it manually together with its core board .dtsi file, and I put them in the dts folder and modified the Makefile to compile your .dts file. For the linux defconfig I used the defconfig from the firefly kernel tree (original v3 kernel, not mainline) since was not sure what the correct defconfig was I should use. I can now boot the kernel but I don't have any graphics output via HDMI. I assume this is because you haven't added HDMI out yet? I haven't manually installed any modules in the rootfs yet after compiling the kernel and haven't manually added any drivers yet. Should it be a matter of adding HDMI suport to your .dts file for the reload board to get basic graphics output working with mainline, or is there more to be done?

[hizukiayaka]

Those dts files for firefly reload have been merged into linux next. Anyway, that dts is designed for mainline not rockchip develop branch, you need a extend property "supports-sd;" in sdmmc node to enable the support for SDMMC.
You may meeet such problem with this branch. Besides, I think the HDMI would work in mainline, but I have not confirmed it yet, you may have a try.

[bschiett]

Thanks, I tried enabling it by setting the status of hdmi and i2c5 node to okay in your reload .dts file using the 4.8.1 stable branch on mainline but that was not enough? Is there anything else I should check?

[bschiett]

In the rockchip kernel repo, "supports-sd;" is already in the sdmmc node,
in the file rk3288-firefly.dtsi. It's just that as soon as I enable the
lvds node and try to boot from SD, the kernel can't find the SD card
anymore so it can't find the root FS. Of course, this is for the classic
firefly board and not my reload board, maybe on the reload board the pins
used for lvds are the ones for the sd card so the moment I turn on the lvds
I disable the sd automatically?

In the mainline, I had no problem booting using your reload .dts but there
I haven't switched on lvds yet because some driver code seems to be missing
and I'm not sure what I need to import.

hi
try this patch
https://patchwork.kernel.org/patch/9348571/

[wzyy2]

And the endlessly looping is caused by networkmanager bug.
I have fix it in this commit

[bschiett]

I tried this patch but nothing changed, for some reason now that i've
enabled hdmi and lvds in my .dts file the sd card is no longer found by the
kernel ... I now have:

LVDS shouldn't affect sd-card.
Could you show me your LVDS dts?

[wzyy2]

The DTS you send seems no problem.
Try add rootwait to bootcmd.

[bschiett]

I think the problem with the SD card not being found might have to do with
the regulators for vcc_sd and vccio_sd, I read that vccio_sd has to be able
to switch between 1.8v and 3.3v depending on the type of SD card (high
speed)? Maybe the .dts is missing some definitions to make this possible?

Firefly don't support uhs, they have a hardware bug in it.
You should remove any sd-uhs-* in sdcard dts node and vccio_sd will not switch between 1.8v and 3.3v.

[bschiett]

Thanks, I will try it.

I restored the sdmmc settings and I still have the same problem - kernel
doesn't find sd card and thus can't mount root fs ... for some reason when
i turn on lvds stops the sd from working, I don't understand ... I'll try
again with Randy's original reload .dts without my changes to see if it can
boot from sd (it did when I first tried it)
