How to Update Linux Packages in the HMI SDK¶
Page Information
The information provided on this page has been verified using the following SDK versions and evaluation kits (EVKs):
- HMI SDK v2.3.1.0 (Yocto 3.1.31 (dunfell), kernel 5.10) using RZ/G2L, RZ/G2LC, and RZ/G2UL EVK
Last updated: December 23, 2025
The HMI SDK is configured using RZ/G Verified Linux Package (hereinafter referred to as "VLP/G") or Board Support Package (hereinafter referred to as "BSP"). When the VLP/G or the BSP in the HMI SDK is updated to fix issues, you can replace the VLP/G or the BSP with new one.
Updates of VLP/G v3.0.7¶
HMI SDK v2.3.1.0 uses VLP/G v3.0.7, but some issues were detected in the VLP/G. VLP/G v3.0.7-update3 was released to address vulnerabilities and improve drivers in VLP/G v3.0.7.
Changes¶
Changes in VLP/G v3.0.7-update3 are listed below.
| Features | Description |
|---|---|
| Kernel | The VLP/G v3.0.7-update3 includes several minor kernel fixes. |
| U-Boot | Update vmmc and vqmmc settings for eSD mode. Configure U-Boot to set a random MAC address. |
| CVE-2024-53104 | Fix out-of-bounds write by skipping UVC_VS_UNDEFINED frame parsing in uvc_parse_format (media: uvcvideo). |
| CVE-2025-4802 | The VLP/G v3.0.7-update3 includes the patch for the glibc vulnerability. |
| glib-2.0 | Updated to glib2.0_2.58.3-2+deb10u8. |
| multimedia | Update runtime dependencies, fix MMNGR issues, and add GRAY10_LE64 support to GStreamer. |
| attr, binutils, busybox, coreutils, gcc-8, gnupg2, gzip, kbd, libassuan, libgcrypt20, libunistring, nss, openssh, openssl, perl, pkg-config, pseudo, quilt | Switch to the ELTS mirror to prevent removal from the Debian Buster mirror: - attr, coreutils, gcc-8, gnupg2, gzip, kbd, libassuan, libgcrypt20, libunistring, nss, perl, pkg-config, pseudo, quilt Upgraded packages: - binutils 2.31.1-16 -> 2.31.1-16+deb10u1 - busybox 1.30.1-4 -> 1.30.1-4+deb10u1 - openssh 7.9p1-10+deb10u2 -> 7.9p1-10+deb10u5 - openssl 1.1.1n-0+deb10u6 -> 1.1.1n-0+deb10u7 |

How to Update VLP/G from v3.0.7 to v3.0.7-update3¶
To update VLP/G v3.0.7 in HMI SDK v2.3.1.0, build the HMI SDK by following the instructions below.
i. First, perform instructions at step 1 and #1 through #4 at step 2 in How To Build HMI SDK.¶
Note
You do not need to download the HMI SDK source code package at step 1. Due to the update of the VLP/G, source codes of some modules were updated. So, you will get new source codes over a network in this build process.
ii. Next, replace meta-renesas with new one as follows:¶
cd ${WORK}
rm -rf meta-renesas
git clone https://github.com/renesas-rz/meta-renesas.git
cd meta-renesas/
git checkout -b tmp BSP-3.0.7-update3
iii. Then, proceed with #5 through #8 at step 2 in How To Build HMI SDK, but skip #7 at step 2.¶
Note
You can skip #7 at step 2 because it shows instructions for offline build using the source code package.
iv. Finally, run bitbake command to build images.¶
Note
A change of EMMC setting in #9 at step 2 is no longer necessary for VLP/G v3.0.7-update3.
If you need to create an SDK toolchain, run bitbake command as follows.
Note
A change of SW_SD0_DEV_SEL setting in #9 at step 2 is no longer necessary for VLP/G v3.0.7-update3.
If you need to create an SDK toolchain, run bitbake command as follows.
After building images or SDK toolchain, you can find them in the following directories, respectively.
- Images:
${WORK}/build/tmp/deploy/images/${BOARD}/ - SDK toolchain:
${WORK}/build/tmp/deploy/sdk/
