    Hello.

    So I looked around for a better place to post this, but, I'm not finding a better spot. If there's a better spot, please move the thread!

    I got an Asus Tinkerboard S for Christmas. Which is cool, I've been wanting to get Retropie going on one for a while now. But I've bumped into a bit of a problem with it and there's next to nothing out there to help me. So I turn to the [H]!

    The TB S has 16GB of onboard eMMC storage, and I bought a 64GB SD card to augment that. I downloaded an Armbian image that has Retropie already installed, and flashed it to the eMMC storage. That part worked as expected: I plugged in the TB S to my computer with a USB cable using its microUSB port, and turned on, my computer dinged as though a new device had been found, and the TB S showed up in Explorer as writable flash memory. I used Etcher to write the image to the eMMC and that was that.

    However, after flashing it, the TB S wouldn't boot. Nothing came up but a black screen. I had read this could happen on first boot, so I waited it out. I even waited overnight, hoping I just wasn't giving it enough time, but no dice.

    So, I read that what I needed to do was download an official TinkerOS image, flash it onto the SD card, install the SD card in the TB S, set the jumper on the TB S to Maskrom mode, and plug in the TB S to my computer via the microUSB port. So I did all that. The TB S boots fine in this way using a 5v/3A power supply plugged into the wall, but when I attempt to use a USB cable running to my PC instead, the TB S turns on for a few seconds, then turns off before there's any screen activity. Additionally, I should add that this behavior continues even if I use different USB cables, and different PC's as well.

    Did I somehow brick this thing, or at the very least, damage it? Not sure what to do next. I suppose I could re-flash the SD card using a different Retropie image, but that would just be ignoring the eMMC storage on the TB S.

    Any thoughts?

    Thanks in advance!

    According to this person, you need to boot the Tinker first with the PSU, then it should be able to run off of USB.

    And this is from ASUS...

    Thanks for the reply!

    I admit, I had not considered the fact that the 4x standard USB ports would be able to provide power to the unit. One thing I did try already was modifying a different 5v/3A power supply to power it via the GPIO header. This worked to power the board up, but when I plugged it into my computer via a standard USB cable from one of the four normal USB ports, my computer did not detect it.

    I'll give it another try tonight and see what happens.

    So apparently I can boot the TB S via PSU, then plug in a USB cable from one of the TB S's four ports to my PC, then disconnect the PSU and it continues to run. But, in no circumstance have I been able to get my PC to "see" the TB S as USB mass storage.

    The only way I can do anything with the TB S at this point is to keep the jumper on Maskrom mode, apply power via the PSU, and boot off the stock TinkerOS image on my SD card. I've been unable to access the eMMC storage in any way.

    I think my board is borked.

    Not yet. I plan to soon, I've just gotten wrapped up with other stuff lately. Once I do (sometime this week), I'll report back here.

    Asus issued me an RMA for the TB S. However, it's a "repair/return" warranty; they want me to pay return shipping and wait two weeks while they determine how/if they want to repair it. So I just set up an exchange with Amazon, it'll be here in two days and they sent me a return label for nothing. /shrug
