And what about USB ports support? Did anyone try to port collabora's patch for rock5b? https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/commit/2c84ba3b660e93c67a02368b278641571945e9bb

Lowering emmc max frequency to 150M did the trick. I've checked eMMC DTS sections on legacy and collabora and they are the same. Does that mean the chip is bad?

Using this board with Armbian_23.08.0-trunk_Nanopct6_jammy_collabora_6.5.0-rc1.img built with Armbian build, everything's ok when running from SD card, but after copying stuff to eMMC with armbian-installer and running from eMMC I get things broken: - getting lots of IO errors like this in dmesg: I/O error, dev mmcblk0, sector 344488960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2 Also I've noticed that the disks structure is quite different on SD and eMMC, so eMMC has extra devices: - mmcblk0boot0 - mmcblk0boot1 and there's nothing like this on SD Please bring on some light how to fix this. dmesg..txt
