The eMMC is still not detected. Kernel log: [ 4.621568] mmc2: error -110 whilst initialising MMC card [ 4.627066] mmc2: Failed to initialize a non-removable card Working devices: [ 4.502846] mmc0: new high speed SDXC card at address aaaa [ 4.508907] mmcblk0: mmc0:aaaa SC64G 59.5 GiB [ 4.551951] mmc1: new high speed SDIO card at address 0001 The system boots correctly from the SD card, but the onboard eMMC (mmc2) is not initialized. There are also still Ethernet issues. After connecting through PuTTY, the system sometimes hangs when running dmesg, and the network connection becomes unstable or unresponsive. System information: Thanks

@JamesCl Sorry, It's ok with 100m, but 1000m also doesn't receive an ip with dhcp. Guess it is a dtb problem or maybe uboot

Hi ... Thanks @Evgeniy evotronik. Yesterday I downloaded the image "Armbian_community_26.2.0-trunk.886_Orangepi-4a_trixie_edge_7.0.5_minimal.img.xz", but the Ethernet and eMMC issues are still present. I will apply the Ethernet patch. Thanks again.

Hi @Tavares R You should definetly check the "Media framework installer v0.1" by Jock, on this link -> https://forum.armbian.com/topic/34923-csc-armbian-for-rk322x-tv-box-boards/page/10/#comment-102655 Also, this other link contains a repo to install some patched libs to at least use decoded video -> https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/ Hope it helps, but reality check is the rk3229 is just too weak to properly handle a full DE running a modern browser... Something also worth trying is to enable the "cpu-hs" overlay. it will "overclock" the rk3229 from 1200Mhz to 1400Mhz, giving some extra performance, but keep low expectations... PS: Are you brazillian by any means? Tavares is a very common last name in Brazil.
