@jock if I recall correctly, I have tested it in both folders and it made no difference, any other ideas ? yes, using a legacy kernel.

Hi @jock , thanks if you can help with this. I'll do a more complete post. If not enough I can post the whole dmesg, later

hi @ilmich, thanks for the help I can't test the box right now, only on Sundays and even then it's difficult but I have some logs, maybe it's helpful ? cat dmesg2.txt | grep -i sdio -A5 -B5 [ 4.911371] Bluetooth: HCI UART protocol ATH3K registered [ 4.917876] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 4.924728] Bluetooth: HCI UART protocol BCM registered [ 4.931574] usbcore: registered new interface driver bfusb [ 4.938344] usbcore: registered new interface driver btusb [ 4.944845] Bluetooth: Generic Bluetooth SDIO driver ver 0.1 [ 4.952172] cpu cpu0: leakage=5 [ 4.958698] cpu cpu0: leakage-volt-sel=0 [ 4.965482] cpu cpu0: Failed to get pvtm [ 4.974092] cpu cpu0: avs=0 [ 4.980660] cpu cpu0: l=-2147483648 h=2147483647 hyst=0 l_limit=0 h_limit=0 [ 4.987149] cpu cpu0: failed to read out thermal zone (-22) [ 4.994450] cpu cpu0: failed to find power_model node [ 5.000172] pwrseq_simple sdio-pwrseq: GPIO lookup for consumer reset [ 5.004832] pwrseq_simple sdio-pwrseq: using device tree for GPIO lookup [ 5.009496] of_get_named_gpiod_flags: parsed 'reset-gpios' property of node '/sdio-pwrseq[0]' - status (0) [ 5.014887] Synopsys Designware Multimedia Card Interface Driver [ 5.020518] usb 6-1: New USB device found, idVendor=062a, idProduct=4c01 [ 5.020572] dwmmc_rockchip 30000000.dwmmc: IDMAC supports 32-bit address mode.

@TU-Student , hello, I predict someone will tell you to use an uart to usb converter. I am no expert on this, but I would guess maybe in pic 1 those 4 pins on the lower part are the uart ? ? please don't try before testing with a voltmeter or something ... @ilmich , great ! my ssv6051 isn't working yet. maybe one day i'll be able to debug it.

@ojogoperdi ? ? It is indeed very possible to boot from sdcard without touching the internal storage, my sd image does it, and I know some others have done it too. My parents box has their Android intact and they still think android is so much better than linux 😄

@jock I didn't know the sellers could have that much profit !

@fabiobassa I agree. I think back some decade ago, when the tv boxes have appeared, then you could buy some box that actually matched the description. they often also had that cool usb drive appearance. But then now they are really popular, especially some models. here I think the most famous is that mxq pro box. So now when you buy it it's a real lottery, it can be anything. especially because now the sellers want to advertise a 64 bit cpu and sell something worse. I was trying to boot linux for rk33xx and failing, only understood what was going on when I installed a terminal emulator and then saw user rk322x.

Wow ! Can I have one ? ? here I tested a sdcard image on my parents mxq pro box, and for basic tasks it's fine. Chromium basic browsing libreoffice etc! And of course all the command-line programs and servers will work fine too. From what I read tx9 should have an amlogic cpu, so no wonder why some of them aren't booting ?
