Ubuntu 20.04 LTS , Kernel 5.15.0-71-generic
(long term) I need to log into this 2x2 board's internal Petalinux, so that
I can configure its firewall. Normally this is done by using minicom and
going in through a serialized TTY protocol. But physically through a USB
cable into the board. (thus a USB-to-Serial conversion is required). The
embedded linux will ask for a username and password, which will be casper
and casper
I am connecting the Micro USB 3.0 from the 2x2 board to a PC. I have
installed the cable drivers of Vivado. I have installed kernel drivers for
cp210x, usbserial, and ftdi. dmesg | grep tty shows nothing new. dmesg |
grep USB shows nothing new. lsusb does not show a connection to this board.
There is no physical problem with the cables as this board connects and
*communicates
fine with the PYNQ toolchain.*
(Additionally I have even tried to create a serial connection to this board
with a separate PC running Windows 10. Silicon Labs VCP drivers did not
work. Silicon Labs Universal drivers did not work. Silicon Labs Dual CP2105
USB to UART bridge Standard COM Port did not cause the computer to
recognize this board.)
What am I doing wrong here? Should I purchase a Xilinx Platform Cable II?
Or other?
Thank you and best regards,
Ken Semanov
