Help to unbrick a TVbox x96 S905x

Okay, all clear then!. Again Thank you both for your help to me and this great community! I'm going to use the newest builds for daily use and if I find any other bug i'll report them.

Hi again!

I've been using the latest "box" stable image this week without issues so far. I would like to know if there is a way to completely turn off the USB ports, because when I turn off the tv box, the USB ports still active. Mainly to save energy and prevent the flash drives from running unnecessarily (since some tend to get warm).

The behaviour in suspend is largely determined in u-boot firmware.. but that's all I know. It's not my area of expertise.

Okay, i understand. I figured it wouldn't be easy to change. I tried a guide from a thread on this forum, but it didn't work. Anyway, at least the flash drive LED turn off when the system shuts down, so I'm guessing they're using very little power in that state.

Thank you again for your help!

This is normal. GXL suspend_fw doesn't provide for complete USB power down. The voltage is simply reduced to the value defined by the 'CONFIG_VDDEE_SLEEP_VOLTAGE' constant. Interrupt autoboot in u-boot and run 'gpio status -a'. Check if something like 'hdmi_5v' (input) appears in the log. If not, then vcc5v is not supplied to USB at all. Then run 'usb start' and then 'gpio status -a' again, and check the log. If you see something like 'hdmi_v5' (gpioh_3, output 1), then you've supplied 5V to USB.

Hi again Bumerc and thank you for your help!

Since I don't know exactly how to interrupt u-boot, I decided to do that by the direct way: I measured the vcc pin of the usb port with my multimeter and there is always 5v, whether the box is on or off. The only difference, as I mentioned in the previous post, is that the flash drive's LED turns off when I turn off the box.
