Yocto Image for H3ULCB+Kingfisher M04

What is the best way to create a Linux Yocto (preferably 3.21) for the H3ULCB+Kingfisher M04 configuration?

I tried the build instructions from here, but the image doesn't boot:

During the Kernel startup I get a panic:

[ 1.531217] loop: module loaded

[ 1.537959] renesas-rpc ee200000.rpc0: using DMA read (dma0chan0)

[ 1.544521] Bad mode in Error handler detected on CPU1, code 0xbf000000 -- SError

[ 1.552007] Internal error: Oops - bad mode: 0 [#1] PREEMPT SMP

Full details here:

How can I build a Image which supports the Kingfisher features (especially 8ch. audio and USB3.0):

07:03, 26 March 2020


I confirmed that Yocto v3.21.0 is booted on H3ULCB(ES2.0 8GB) + KF(M04).

I checked your boot log, and noticed IPL and U-boot is old.

So, please update IPL and U-boot, then try to boot again.

Best regards.

01:01, 27 March 2020

Thanks for your help!

I have to admit that the boot log from the link above is not mine (just the error was the same).

My u-boot and IPL is newer, here is my full log of the kernel Oops:

It is a dual-boot system which can also boot Android (for development), so the bootloader is from the Android build. I hope that's not the problem?

Here is my u-boot environment:

01:59, 27 March 2020

Sorry, I have never used android on H3ULCB + KF.

But, I tested Yocto v3.21.0 on H3ULCB(ES2.0 4GB) + KF(M04) again.

And I confirmed that it works.

How about using yocto bootloader ?

if yocto can be booted, android bootloder may not be good for yocto...

Best regards.

03:18, 27 March 2020

Thanks for your help Y.H. With the Yocto-Firmware it boots as expected.

How I need to get the Android part working again, but boota is not supported in the Yocto's u-boot. But that's a different story now.

07:44, 30 March 2020


I prepared android 9 for H3ULCB(ES2.0 4GB) + KF(M4), and tested for booting yocto.

In my environment, yocto was booted with android's IPL and U-boot.

If you use old version of android, how about updating it ?

HDMI DU_DOTCLKOUT frequency on Kingfisher


What is the maximum supported frequency for DU_DOTCLKOUT on Kingfisher (not ULCB)? Need to understand limitations of "SoC's DU (digital RGB out) -> ADV7513 (HDMI)" pipeline. According to chapter "4.13. HDMI" of maximum supported resolution is 1920x1080i. But this manual does not tell maximum framerate and so maximum supported frequency is not clear.

Sincerely, Yaroslav

07:43, 21 November 2019


The maximum frequency of Kingfisher is 100MHz(DOTCLKOUT: Min 10ns).

01:48, 25 November 2019

Thank you.

How to use Leopard Imaging LI-OV10635-GMSL


I am trying to use Leopard Imaging LI-OV10635-GMSL with Kingfisher.
Is there a difference in BSP build procedure for LI-OV10635-GMSL and RDACM21?
Is there any difference in handling on Linux?

Best Regards.

19:04, 1 September 2019

Please add the following to bootargs when linux starts up. ov106xx.dvp_order=0

23:02, 4 September 2019

I want to try it as soon as I get a camera.
Thank you very much.

19:58, 5 September 2019

I was able to solve this.
Thank you very much.

About 60fps Camera for R-car

I'm looking for 60fps Camera for R-Car.
Because IMI camera RDACM21 is discontinued.
So, Can you please give me information about 60fps Camera that has been used successfully for R-car Kingfisher.
Best Regards.

00:56, 20 August 2019

The following cameras are currently supported:

Development will continue, but the schedule is undecided. Please check the eLinux site regularly.

USB3.0(CN2) cannot use with M3 SK. This is a limitation of M3 SK.

If you want to use USB3 ports, please use the H3 SK.

LVDS Camera driver source code

Is there LVDS camera driver source code available?
If any, please let me know the source code file path?

HDMI output

Is Kingfisher's HDMI output terminal CN49 ?
Can I use StarterKit's CN4 (HDMI mini) ?

01:29, 19 April 2018

You can use both (at the same time).

18:48, 19 April 2018

Thank you for your answer.

Debug serial I/F

Is Kingfisher's debug serial I/F CN4 ?
Can I use StarterKit's CN12 ?

01:29, 19 April 2018

Please use Starter Kit's CN12.

About 440p_ComExpress CN1B B055

I am investigating the connection relationship between Kingfisher (* 1) and StarterKit (* 2). (* 1), B055 of 440p_ComExpress is named IrqEXT0xE8 and it is connected with INT of U11 (TCA9539QPWRQ1).
(* 2), B055 of 440p_ComExpress is named AVB_AVTP_MATCH / SCL5 and is connected to B11 (AVB_AVTP_MATCH_A) of R-Car SiP.
How will it work (how do you communicate) with B055 when connecting (* 1) and (* 2) together?

440p_ComExpress CN1B B055

440p_ComExpress CN1B B055

When Kingfisher upgraded from M04 to M05, it seems that the connection has changed from A079 to B055, so I am investigating the reason.

22:36, 19 March 2018

440p_ComExpress B055 is an output terminal (INT output of IO Expander) for Kingfisher.
Even for StarterKit I think that it is an output terminal (AVB_AVTP_MATCH output of R - CarGen 3).
Therefore, I think that the outputs collide with each other.
Is my understanding wrong?

17:24, 22 March 2018

B055 of KF will be used as GP2_13(input) instead of AVB_AVTP_MATCH.

00:01, 23 March 2018

Thank you very much.

Kernel image for Kingfisher

Is the procedure shown in for SBEV-RCAR-KF-M04 or for the latest version of SBEV-RCAR-KF-M05?

05:26, 8 March 2018

I've never seen SBEV-RCAR-KF-M05 board. I'll check if I get the board.Do you have it?

04:48, 9 March 2018

I also do not have the SBEV-RCAR-KF-M05 board as well.
I am worried about whether the Linux build procedure differs between SBEV-RCAR-KF-M04 and SBEV-RCAR-KF-M05.
If it is different, could you show it?

I have an SBEV-RCAR-KF-M04 board and I was planning to setup it from now.

How to connect Starter Kit to Kingfisher and use Starter Kit's JTAG I/F

I am using Kingfisher (SBEV-RCAR-KF-M04(Advanced Model)).
With Starter Kit connected to M04, Kingfisher manufacturer taught that Starter Kit's JTAG I/F can not be used.
However, by correcting the circuit on Starter Kit side, he taught him that Starter Kit's JTAG I/F can be used even when Starter Kit is connected to M04.

Please tell me about Starter Kit circuit correction contents necessary to use Starter Kit's JTAG I/F with Starter Kit connected to M04.

19:25, 19 February 2018

I think the problem is that the TMS_18 signal is connected to GND. As one method, cutting the signal of SK seems to be able to avoid the problem. However, I think that it is very difficult to cut short distances from other signals(for me at least).

Anyway, please give me time to cut and confirm.

20:14, 22 February 2018

Thank you for your response.
I will consider the correspondence.

22:27, 27 February 2018

I cut the signal of SK. Please refer to the picture on the back side of SK.


Then, I connected SK and M04 KF and confirmed that JTAG started up.

Note: Cutting the signal is very difficult. I can not recommend it.

22:02, 4 March 2018

Thank you for confirmation.

Wow! You are good with your hands!
I certainly think it is difficult to cut this.
