sorry just switched my box for the first time in a long time. i was wondering if i can seamlessly upgrade to the latest Armbian without losing hardware acceleration included in RK3288/RK3328 Legacy Multimedia Framework or is it only for Debian Buster? is kodi-gbm (RKMPP) still viable? is there a compatible version much higher than 18.9 "Leia"? thanks!

@Ikesankom sorry for the late replies. wait can you share us the code for that? i probably might need it for checking on stuff. also i get weird SSH timeouts whenever i overload the board for some reason. thanks!

@crr sorry if it took this late, i dont usually read the forums that much. also i downtimed my media box for other reasons (cleanup, transferring files, diagnostics) with that said. yeah i should try that in the future honestly. but for now i just ignored this because this happened spontaneously, with only same thing being there's failing HDDs. i removed the offending HDDs and that worked. the power supply has an ammeter and voltmeter on it. it stays under 0.7A to 1.4A whenever i use it on my usual usecase. problem persists. oh right i forgot to mention, i use a boost down converter here with adjustable current and voltage. checking back i use 5.7V @ 3.0A. should i increase it to 6v? tinkerboard can handle up to 6.2V, everything else is regulated. i dunno if this is valid, but i used an ATX PSU on this because i can separate the SATA power lines of my internal SATA. so the current running through the USB lines is all just for powering the SATA-USB hub. problem persists even if i only connect a single (failing) drive i wonder if there's like this on tinkerboard? thanks

to recap: Tinkerboard (rev 1?) has 2 USB devices (from RK3288's internal ports), one for the Realtek HD audio, and one for the 4 USB ports (Genesys 4-port USB hub). while i have no info for the HD audio, the hub is powered via the 5V lines (noted as V5 pin in the datasheet). my mistake would be not checking if all the 5V power lines are shorted, or it's just connected to the hub. there's an option to NC the pin if using an external regulator (say, the RK808 power management chip?) The LAN is separated to the hub and instead directly connected to the RK3288 At least the datasheet for RK3288 says. no pinouts whatsoever so i think this is all inside the chip I noticed this strange behavior across unique setups (LAN connected, 1x keyboard-usb combo, and even 1x-3x USB SATA devices (power separated since these are 3.5 inch drives)) Sometimes the USB hub disconnects for no particular reason while turned on "disconnects", i mean, when SSH over the device the `lsusb` appears nothing but the Realtek devices. the Genesys hub isnt listed. i wouldnt associate it with power considering that the whole board only consumes 0.7A Max (on all those setups) when connected to an ammeter this carries over across reboots and wont reset until power was disconnected off the wall. i need to rest the board for a while (like several minutes) without power and peripherals. probably a polyfuse triggering and resetting? this also happens on occasions when i plugged failing drives. i was thinking if it has to do with `usb 1-1 disconnected` where the kernel restarts the USB devices on General Failure on the SATA commands. but it's a weird behavior that it restarts the whole hub rather than the device itself. Sometimes the LAN disconnects as well simultaneously cant SSH over the LAN, only via WiFi. this can be resetted via a reboot, unlike the USB hub. any help would be appreciated, or tips to recreate this. i was thinking of using USB load testers as a stress test. a limitation of mine is also me not providing /var/log/syslogs on these events considering i cant access the device when this happened.

weird "bumping" this old question but here are some of my findings, just quick answer (my tinkerboard runs on 2x USB-SATA HDD's, 1x 2TB, 1x 500gb, and 1x 1.5TB external hard drive) 1. flash firmware on your USB-SATA. it shuts down every 10 minutes or so, depending on the chip, but other firmware dont have those issues (eg, those HDD cloners). check your SATA-USB controller for reflashing. this is left as an exercise to the reader. 2. remember that tinkerboard isnt 4x usb but rather 2x USB device, 1 lane is reserved for the audio controller and the other lane is split to a Genesys 4USB hub controller. since this is USB2.0, you're stuck at 480Mbps, around 60MB/s transfer rates. since it's half-duplex, it's halved to 30MB/s on the hub alone. expect a max throughput of 30MB/s shared. real life performance may vary: i sometimes get full 30MB/s on one device, sometimes, all devices are just the slow. depends on your use case, 30MB/s is just *slow* that's pretty much it about my experiences on the device. now i'm getting a used 500GB HDD running e2fsck. i hope it works well, for 2 days it seems okay. this is while one HDD runs tar while the other does downloading. also be wary of power consumption: 3A on the whole device (take note without peripherals, tinkerboard runs at ~1A on idle and ~2.5A on full load) . go beyond that will cause instability (either boot issues, or in my case USB hub stops working.) i wont recommend using a hub (no issue in power, but slow-downs are a real pain in the butt) but instead those USB-Y splitters that split the device's power. use a separate USB power brick to power the devices alone (i taped my power lines going on the device's side, just to be safe.)
