PCM3168A driver for Kingfisher

PCM3168A driver opened in eLinux seems to have some tentative implementations to support LINEout x8ch (CN12) for Kingfisher. e.g. no support 16_LE. If my understanding is correct, can I ask if there is any plan to replace the tentative implementation with permanent one?

Renesas will post patches to the upstream. However schedule is undecided.

Enabling Reset button/Power button functionality on Kingfisher + M3 Starter Kit

Reset button (SW8) and Power button (SW9) do not work when M3 starter Kit connected to Kingfisher board.

We need this in order to evaluate fastboot feature with Camera connected to Kingfisher.

Any workaround?

Note: SW8 and SW9 work fine without connecting Kingfisher board to M3 starter Kit.

[Use Case]

1. Connect M3 starter Kit to Kingfisher Advanced Model board.

2. Boot up the board.

3. Press SW9 for resetting the board, without physical power disconnection. (Volatile memory should be maintained.)

OR

1. Connect M3 starter Kit to Kingfisher Advanced Model board.

2. Boot up the board.

3. Software suspend the board. Press SW8 in order to power on the board, without physical power disconnection. (Volatile memory should be maintained.)

[Board and other env.]

Renesas RCAR M3 Starter Kit

Sample Loader V3.02 2017.07.04 (M3 Starter Kit)

MiniMonitor V3.02 2017.07.04 (M3 Starter Kit)

Kingfisher Board Version (SBEV-RCAR-KF-M05)


Thanks,

According to the schematic the power supply seems to be controlled from Kingfisher(M05). I think you can not control power from SW8.

Ygohda (talk)‎21:52, 12 July 2018

Is there any switch/workaround to reset the kingfisher board ? Or would this be considered as a hardware limitation and no work around possible ? Although we would hope this is not the case.

Chetan (talk)‎18:06, 23 July 2018

SW9 on Starter Kit can reset to CPU( and devices on Starter Kit). However it cannot reset to devices on Kingfisher.

Why do you need reset rather than SW6 on Kingfisher?

Ygohda (talk)‎21:42, 26 July 2018

>>Why do you need reset rather than SW6 on Kingfisher?

We want to evaluate suspend to RAM mode of hibernation. For this, we are expecting to keep the power ON for the board so that during hibernation the contents of RAM are not lost. Software control for reset is not present so we need a RESET functionality equivalent like provided by SW8.

Also we need kingfisher board for getting CAMERA interface CN29 access to M3 target.

SW6 erases the RAM contents so we are not able to use it.

Would you please let us know any workarounds, if possible, for this use case ?

Thanks in advance.

Chetan (talk)‎17:11, 31 July 2018

KF doesn't support Suspend to RAM(S2R).

In order to support S2R on SK+KF, it is necessary to redesign the power control schematics on KF.
(I have never heard of such a plan.)

Ygohda (talk)‎18:32, 31 July 2018

We understood no support considered for S2R so far. Thanks, Gohda-san, Chetan-san.

Camera Low lever test issue on H3 Adas

Hi

i build a yocto 2.23.1 with ADAS setup for H3 v2 board and an adas view card (boot with Image-r8a7795-h3ulcb-view.dtb)
but i have a crash when i start the surround test:

How to execute OP-TEE cryptographic algorithms directly from ARM Trusted Firmware

I want to evaluate cryptographic algorithms on the boot loader before Linux starts up.

We plan to include evaluation software in ARM Trusted Firmware (bl31-h3ulcb).

ARM Trusted Firmware has no encryption algorithm, so we are considering using a library in OP-TEE (tee-h3ulcb).

For example, in evaluating signature verification using RSA, the following processing is considered necessary.

・ Register the public key and secret key.

・ And generates a hash value of the evaluation target data. (For example SHA 256)

・ Generate a signature by encrypting the hash value with the secret key.

・ Generate a hash value by decrypting the signature with the public key.

Among these processes, I do not know how to register the public key and secret key to OP-TEE.

Please tell me what kind of processing can be realized from ARM Trusted Firmware.

(If you have product planning, )I think that you should officially contact Renesas.

Ygohda (talk)‎02:31, 12 December 2017

I am not a product planning representative.
I'm considering running cryptographic algorithms implemented on R-Car H3 on a boot loader on which Linux is not running.

I will concretely describe what I can not realize.

First, when ARM Trusted Firmware jumps to the address where the OP-TEE function exists, an exception will be raised.
After that, "plat_panic_handler" will be in infinite loop state.
I guess that it is probably guarded by MMU, but I do not know how to deal with it.

Second, About signature verification using key of RSA.
In order to register the key of RSA, I guess using functions like "alloc_rsa_public_key" and "alloc_rsa_keypair" in OP - TEE.
However, I do not know how to use functions such as arguments and procedures.

How to use usb webcam in H3??

How to use usb webcam in H3??

Because I use python opencv

>> cap = cv2.VideoCapture(0)

It doesn't capture webcam

How to solve this problem??

Ipodslessteven (talk)‎10:52, 17 October 2017

Hi

I write information when I checked the usb webcam using Yocto v2.23.0.
I don't understand your detailed environment, but I am glad if this is helpful for you.

Environment:
- H3 Starter Kit
- Yocto v2.23.0
- USB Webcam Logicool C920t

1. Enable the following kernel config.
        Device Drivers --> Multimedia support  ---> [*] Media USB Adapters
                [*] USB Video Class (UVC)
                [*] UVC input events device support (NEW)

2. Modify the gstreamer1.0-plugin-vspfilter
 # vi gst/vspfilter/vspfilterutils.c
   {GST_VIDEO_FORMAT_UYVY, V4L2_PIX_FMT_UYVY, V4L2_MBUS_FMT_AYUV8_1X32, 1},
+  {GST_VIDEO_FORMAT_YUY2, V4L2_PIX_FMT_YUYV, V4L2_MBUS_FMT_AYUV8_1X32, 1},

3. bitbake

4. How to run
 Ex)
 # gst-launch-1.0 v4l2src device=/dev/video16 ! video/x-raw,width=1920,height=1080 ! vspfilter ! video/x-raw,format=BGRA ! waylandsink

 * videoN: Please set according to your environment.
   Ex) In case of M3 SK it was video8.
Ygohda (talk)‎03:38, 23 October 2017

My environment : - Yocto v2.19.0 - USB Webcam logitech HD WEBCAM C525

I refer https://elinux.org/R-Car/Boards/Yocto-Gen3/OpenCL & https://elinux.org/index.php?title=R-Car/Boards/Yocto-Gen3&oldid=449821

sorry I don't know where can I revise the code you say in the first 1. Enable the following kernel config. 

       Device Drivers --> Multimedia support  ---> [*] Media USB Adapters
               [*] USB Video Class (UVC)
               [*] UVC input events device support (NEW)
Ipodslessteven (talk)‎06:33, 23 October 2017

Please refer to the chapter 2.3.2 of https://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html

Ygohda (talk)‎21:54, 23 October 2017

for enter in the configuration of the kernel ( you must have a X server configured because you have a popup with the menuconfig) : bitbake linux-renesas -c do_menuconfig
