I encountered an error that Tegra X1 did not start.(ttyUSB2 is not response.)
Tegra X2 is running. The ttyUSB6 is active and the HDMI XB port is alive.
However, it looks like to setted up for TegraX1(e.g. wall paper shown Xavier A, cat /proc/device-tree/model result is e3550_t194a).
I definitely inserted the HDMI cable to XB.
In addition, I found many errors at syslog.
Also I can flash by
./bootburn.sh -b e3550b03-t194a -B qspi -x /dev/ttyUSB3
./bootburn.sh -b e3550b03-t194b -B qspi -x /dev/ttyUSB3
What is happening?
