Board is dead

crashoverride · Posted at 6/30/2017 01:01:52

After flashing the Android image as requested for diagnostic purposes. I attempted to re-flash the Ubuntu image. The board become unresponsive after pressing the "recover" and "reset" key. It no longer shows up as a USB device. It also will no longer boot. I have attempted the "mask rom" mode as documented and still can not get the device to do anything:
http://wiki.t-firefly.com/index.php/Firefly-RK3399/MaskRom/en

No LEDs are illuminated. Numerous attempts at reset produce no result. The fan on the heatsink is spinning and the SPDIF light can be seen through the connector.

Any suggestions before I return the board?

I hooked up a serial console cable to the board and was able to determine it was not as dead as it appeared.

Copy the code

With the console cable in place, I was able to determine that "mask rom" was not being entered. I used a piece of wire to short the test points and reset the device until it appeared over USB. At this point I was able to erase and re-flash it with the Ubuntu image.

For anyone else that experiences this, the tip is to make sure you have good contact on the test points. Also, its much easier to press the reset button while shorting the pins than it is to plug/un-plug the power connector.

I am trying to flash the Android 7.1 image through maskrom mode, but after I get this:

Download Boot Start
Download Boot Success
Wait For Maskrom Start
Wait For Maskrom Fail

And it says USB device not recognized. Any idea how I can fix this? Thanks!

Off-topic question, since I cannot create a new topic:The official 7,85" EDP display, is it plug-and-play for RK3399 board or does it need some setups in Android?
Question 2: Have anyone successfully tried to connect any non-official touchscreen display to the RK3399? If so, what kind of display was it and how much programming did you actually need to do?
