Uart with minicom - no keboard


#1

Hi,
I installed OpenEmbedded from fastboot following the instructions and try to connect to the board with uart. I see the boot output, both kernel and systemd ,
and eventually get:

dragonboard-410c login:

line. But there is no reaction to the keyboard, not able to write anything.

I see the following errors during boot, are they related ?

[ 5.067272] ov5645 1-0078: ov5645_set_power_on: Enter

just solved it by setting “hardware flow control” to off, in minicom (ctrl+o->“serial port setup” -> “F”)
