Hi Igor,
thanks for your reply. I was able to figure out how to transfer files, but it was quite pain. So for everyone who is interested in this, I provide step-by-step solution, as the details is what is missing. Usually the answer I found was use minicom, hyperterminal etc. without any details. So here we go:
My setup was:
PC with Win 10 (Windows Subsystem for Linux - WSL present)
imx8mm evk
Interconnection between PC and board via USB (PC) - Debug Line interface/mico-USB (board)
Board powered with USB type C from a docking station.
A switch powering the board was set to ON
Establishing connection with board
First we need to establish connection to the board via serial line (Debug line serves as a virtual com port):
option 1) TeraTerm (download and install TeraTerm)
- open TeraTerm
- select "Serial"
- my TeraTerm offered connected devices via serial line, so just select the right COM port
- confirm
Afterwards the terminal should appear (blank)
At this point its necessary to check the serial line configuration, which can be done under "Setup -> Serial Port..." in TeraTerm. (not sure you need to restart the session???)
Press "Enter" and a login prompt should appear. Login to your board.
option 2) use screen utility under WSL (I'm running Ubuntu on my Win 10 OS)
- start WSL
- connect to board like this:
$ sudo screen /dev/ttyS# 115200
(maybe you need to change the privileges for ttyS# via chmod)
The COM# ports are mapped to ttyS#. COM1 = ttyS1 etc. Some info can be found here Serial Support on the Windows Subsystem for Linux – Windows Subsystem for Linux
A blank screen should appear (as in case of TeraTerm), so just press "Enter" and login to your board.
Transfering files from PC to board
On your target board:
$ cd /path/to/directory/where/file/should/be/transferred
Type following command into the command line on your target board and confirm it
$ rz --zmodem 1>/dev/tty# 0</dev/tty#
tty# is your terminal identifier and can be obtained by executing:$ who am i
option 1) TeraTerm
To transfer a file, just navigate in TeraTerm to:
"File -> Transfer file -> zmodem"
A pop-up window should appear and you just select a file to transfer. The file will be transferred to the board and the transfer should terminate.
option 2) screen
Detach from your screen session by pressing "Ctrl + d, Ctrl + a.
Execute:
$ sz --zmodem /path/to/file/to/transfer 1>/dev/ttyS# 0</dev/ttyS#
ttyS# is the identifier of COM port used to establish transfer in previous steps.
A file should be transferred to your target board and the transaction should be terminated. Reattach the session executing in WSL:
$ sudo screen -R -D "session_identifier"
The session identifier can be obtained like:
$ sudo screen -ls
I'll review the steps and update them, as I wrote the instructions from my head.
Hope this will help someone,
Vojtech
