New to linux-rockchip, bought a firefly rk3288 board preloaded with Android, followed the http://opensource.rock-chips.com/ Linux SDK instructions and built everything, but when I was trying to flash images with upgrade_tool (v1.33) like the following, the command never went through and stuck like this:
<code>
sudo ./upgrade_tool ul ./rk3288_loader_v1.06.236.bin
Loading loader...
Support Type: RK320A Loader ver:2.36 Loader Time: 2018-05-31 13:38:53
Test Device Total(1),Current(1)
</code>
tried another one,
<code>
sudo ./upgrade_tool di -p ./parameter.txt
Write gpt...
</code>
wait a long time but still nothing happens.
On firefly rk3288, I did entered "maskrom rockusb mode" by short "clock" and "ground", and lsusb show "2207:320a" usb id, so that is ok. Feels like something is broken during the process.
Thanks in advance for any idea about it.
