Hi Folks. I'm looking for somebody who can test a bootloader image on a Firefly-RK3399 with the default firmware still on the eMMC. If you have a board in that state, can you try to write the image at:
http://www.xs4all.nl/~sibelius/rk3399.fs to an SD card and attempt to boot from it? I'm curious to see if that makes the board boot from the SD card. If that works, you should see the following U-Boot banner on your serial console at some point: U-Boot 2018.01-00077-g373b900341-dirty (Jan 13 2018 - 21:06:01 +0100) Note that you'll need to run your serial console at the crazy speed of 1500000 baud to see anything but garbage. Thanks, Mark
