Multiple Shells? - Virtualisation - IVSHMEM demo

How do I start multiple shells for the IVSHMEM demo?

"uio_read and uio_send need to be started in different shells."

I have Hyperterminal on COM3 where I start U-boot and run jh_mmcboot

"Open two shells, using SSH to log into the board. Execute uio_read in one shell and execute uio_send in the other shell.
#uio_send /dev/uio0 [count] 0 0
#uio_read /dev/uio0 [count]"

You can use ssh connection to open second shell

Does this mean I use an Ethernet port to ssh into the i.MX8 board rather than the serial port?

Or this can be done using the existing COM4 port?

I've figured out how to connect a SSH shell using the Ethernet port on the i.MX8 eval board.

In the COM port shell

$ ifconfig eth0 up

$ ifconfig

Look for the IP address after inet addr

e.g.

eth0 Link encap:Ethernet HWaddr 00:04:9f:07:15:9a
inet addr:169.254.42.78 Bcast:169.254.255.255 Mask:255.255.0.0

Then I start another terminal e.g. I'm using Tera Term to the IP address above 169.254.42.78

The username is root

Where are the "uio*" executables? They are not in the LF_v5.15.32-2.0.0_images_IMX8MQEVK download, but I got the Linux jailhouse demo working (after some work).

Is someone going to update the IMXVIRTUG document?
