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.
