Here what you could do: Download kernel-default package from here [1]. Click on "Grab binary packages directly" from section "Packages for ARM", get the one which end with aarch64.rpm. Save downloaded package. Download latest "minimal" Tumbleweed ISO from here [2]. Specify which modules you think are essential for device to boot. For example: MODULES="i2c-mt65xx spi-mt65xx pinctrl-mt8195 mt6315-regulator phy-mtk-tphy \ mtk-pmic-wrap mediatek-drm mt6359-regulator mt6357-regulator" Create driver upadate package (DUD) [3] from the downloaded kernel package: mkdud --create mediatek.dud --dist TW --install repo kernel-default* Rebuild installation ISO [4] init ramfs with your additional modules specified above. sudo mksusecd --verbose --create mediatek.iso --rebuild-initrd \ --initrd mediatek.dud --kernel kernel-default* \ --modules ${MODULES} -- openSUSE-Tumbleweed-NET-aarch64-Current.iso Test new mediatek.iso. Please try to narrow down required modules. Once you are happy with the result share the lit of modules here. Hope this helps.

I must say that Suse's 'mkdud' and 'mksusecd' are very easy to get started and use. Although there are no dpkg packages, I can use alien to convert them into .deb files, so I can run these debug steps on Ubuntu. When I put all the drivers (about 50+) into initrd.img, it's clear that most of the drivers can be detected. This also includes USB HOST and ethernet. After about half a day of cleaning up, it is now clear that to support the USB host driver (USB PORT 3) on the mt8195-demo board, the following drivers need to be added. This is base on the current iso images and kernel packages. For enable USB HOST: MODULES="clk-mt8195-imp_iic_wrap mt6360_charger mtk-pmic-wrap nvmem_mtk-efuse" The following are the binaries I've used: - kernel: kernel-default-6.5.6-1.1.gc97c2df.aarch64.rpm current-ISO: - openSUSE-Tumbleweed-NET-aarch64-Snapshot20231003-Media.iso I'll do next for enabling the ethernet driver. -- You are receiving this mail because: You are on the CC list for the bug.

Solution: MODULES="clk-mt8195-imp_iic_wrap mt6360_charger mtk-pmic-wrap nvmem_mtk-efuse clk-mt8195-vdec clk-mt8195-venc clk-mt8195-vdo0 clk-mt8195-vdo1 clk-mt8195-vpp0 clk-mt8195-vpp1 clk-mt8195-wpe clk-mt8195-ipe clk-mt8195-cam clk-mt8195-ccu clk-mt8195-img" Compared previous found solution for enabling USB HOST. MODULES="clk-mt8195-imp_iic_wrap mt6360_charger mtk-pmic-wrap nvmem_mtk-efuse" There are more multi media clocks drivers are required, and I just could not to get rid any one from the following list to enable ethernet. "clk-mt8195-vdec clk-mt8195-venc clk-mt8195-vdo0 clk-mt8195-vdo1 clk-mt8195-vpp0 clk-mt8195-vpp1 clk-mt8195-wpe clk-mt8195-ipe clk-mt8195-cam clk-mt8195-ccu clk-mt8195-img" After checking the code, ethernet only depends on 'topckgen' and 'apmixsys' which should be a built-in clock driver already. Is it possible to create a cd-image with adding softdep to ethernet drivers? I'm not sure if re-order the probe sequence will help. The following logs are the 'lsmod' log for used ethernet drivers. realtek 36864 1 dwmac_mediatek 16384 0 stmmac_platform 32768 1 dwmac_mediatek stmmac 282624 3 stmmac_platform,dwmac_mediatek pcs_xpcs 20480 1 stmmac phylink 69632 2 stmmac,pcs_xpcs At last, I could use the modified 'openSUSE-Tumbleweed-DVD-aarch64-Snapshot20231010-Media.iso' with these driver to install Suse on to the mt8195-demo right now. However there still some issue blocking system boot after installation. I'll attach the boot log later. But at this stage, please help to add the solution into pre-built CD/DVD image at least we could get installer to work on mt8195-demo boards.

Hi,
By adding blasklist modules to kernel cmdline in grub I could boot the installation into console.
Do you mean serial console? or tty console via any video port?
"module_blacklist=arm_dsu_pmu,ffa-module,drm,mediatek-drm"
I'm not sure if this is because I've chosen 'server installation' hence I'm not sure if some display relate drivers were not included. Thank you for the supporting.
