RZ-Board HDMI issue

partha123 — Sun, 22 Jun 2025 14:07:45 GMT

Hi,

I uploaded the latest image from the AVNET website to my Rzboard, and now I am getting a display flickering issue.

Upload image: avnet-core-image-rzboard-20241025085125.rootfs.wic

Kernel Version 5.10.201

Note: kernel version 5.10.83 is okay for me. Looks like kernel version 5.10.201 is not working properly

I have attached a video for reference.

Please help me.

Thanks,

Partha

RZ Board Flash Utility

rahuldee1 — Wed, 07 Feb 2024 21:41:52 GMT

I plan to use the RZ Board Flash Utility to upgrade the bootloader and system image files using the option.

./flash_rzboard.py --full

Please let me know if the following physical settings remain the same for both bootloader and system image download.

Place RZBoard into “SCIF download boot-mode” by setting BOOT[2:0] to b101 ie.

- Set BOOT2=1 by strapping J19-pin1 to +5V (ie. connect it to J1-pin2 on the 40pin header)

- Set BOOT1=0 by strapping SW1.1 = ON

- Set BOOT0=1 by removing SD card from MicroSD slot

Thanks,

Rahul

I'm using

Poky (Yocto Project Reference Distro) 3.1.14
Linux rzboard 5.10.83-cip1-g11a8126702 #1 SMP PREEMPT Tue Apr 5 23:00:00 UTC 2011

I also tried compiling and running app_hrnet_cam and even after some minor changes, the furthest it can get is
VIDIOC_STREAMON, where it always fails with EPIPE. This is consistent with the yavta errors

The V4L documentation suggest EPIPE means the media-ctl commands are wrong.

Is there any other camera known to work besides ov5640? How about ov5647. I built the driver and tried it but, media-ctl won't even recognize it.

Appreciate some help.

RZBoard V2L : Codec Library version

shingo-kj — Wed, 22 Mar 2023 13:16:25 GMT

The version of the CODEC library differs between the documentation and the script on GitHub.

RZBoard-Linux-Yocto-Development-Guide-v2.3.pdf : V0.58 (RTK0EF0045Z15001ZJ-v0.58_EN.zip)

https://raw.githubusercontent.com/Avnet/meta-rzboard/rzboard_dunfell_5.10/tools/create_yocto_rz_src.sh : V1.0 (REN_VEDIO_CODEC_LIB_PKG_EVAL="RTK0EF0045Z15001ZJ-v1.0_EN)

If the documentation is out of date, it would be helpful if you could update it.

Best Regards,

Shingo

List of out-of-the-box-compatible mipi cameras

tzoumas — Fri, 17 Feb 2023 14:43:01 GMT

Is there a list with available mipi camera modules that work out of the box with the RZBoard and the pre-build yocto image that comes with it? I mean with alternatives other than the one provided in Avnet site (www.avnet.com/.../)

Package manager for RZBoard

rahuldee1 — Tue, 06 Dec 2022 23:11:34 GMT

Which Linux package manager does the RZBoard use?

I wish to install additional packages such as SoX (Sound eXchange) and some Python
packages using pip.

RZV2L_AI_Eva_SW folder & DRP-AI translator code on RZBoard

rahuldee1 — Mon, 21 Nov 2022 22:45:30 GMT

Hello,

Just received the RZBoard.

I logged in using Quickstart and see this folder in the root directory - RZV2L_AI_Eva_SW.

There is a .sh file which contains expected CLI arguments. How to use the software inside the RZV2L_AI_Eva_SW folder of the RZBoard.

Is there sample code to serve as a starting point for code created using DRP-AI translator?

Thanks!

RZBoard Technical Documents

peterfenn — Wed, 05 Oct 2022 19:29:42 GMT

In this time of inventory shortages (with SBC boards like Raspberry Pi really scarce lately) there is local US warehouse stock and boards are being shipped, of the power-efficient new AI-accelerated RZBoard V2L dev board!

Intended as a "Raspberry Pi form-factor" community board (with versatile hardware expansion options) this Renesas RZ/V2L based board (with DRP-AI accelerator, H264 enc/dec and GPU cores) is ideal for AI-enabled video camera applications, especially in power-constrained/battery-powered use-cases.

Availability of technical documents is being addressed, with documents like RzBoard V2L Hardware User Guide scheduled for release on the product webpage (avnet.me/RZBoard-V2L) this week

RZBoard Bringup

raemond — Tue, 27 Sep 2022 18:58:06 GMT

Hi, I just got a RZ board and the card included with the kit mentioned a quick start guide at avnet.me/RzBoard. This redirects to, www.avnet.com/.../ which doesn't have any such guide. Could you direct me to one?

I noticed that the the linux partition is only 2.5GB of the available ~29ish GB. Any tips on resizing the partition?
