previously built serialportstream at $HOME/Apps/serialportstream following https://github.com/jcurl/SerialPortStream

trying to execute:
LD_LIBRARY_PATH=$HOME/Apps/serialportstream/dll/serialunix/bin/usr/local/lib64:$LD_LIBRARY_PATH dotnet ./EfsTools.dll targetInfo

simply returns Critical error. Error 2

The <efstools port="xxxx" ...> in the EfsTools.dll.config file should point to an existing serial device. In my example above, it's /dev/ttyUSB0 but still doesn't work. It doesn't work with auto or Auto.
See related commit c81a15d !

Sadly I don't have any clue how to define a serial port to an Android device which is in adb DIAG mode already. 🤷

Sadly I don't have any clue how to define a serial port to an Android device which is in adb DIAG mode already. 🤷

lsusb output:

Bus 005 Device 039: ID 05c6:9091 Qualcomm, Inc. 

Echoing 05c6 9091 into /sys/bus/usb-serial/drivers/qcserial/new_id did a little trick:

[51418.168657] qcserial 5-1.4:1.1: Qualcomm USB modem converter detected
[51418.168802] usb 5-1.4: Qualcomm USB modem converter now attached to ttyUSB0
[51418.172262] qcserial 5-1.4:1.2: Qualcomm USB modem converter detected
[51418.172364] usb 5-1.4: Qualcomm USB modem converter now attached to ttyUSB1

After setting the connection params (port="/dev/ttyUSB0" baudrate="115200") in EfsTools.dll.config it didn't really helped:

$ dotnet EfsTools.dll targetInfo
Critical error. Error 5

[shvchk]

Can confirm. Steps to reproduce:

1. Build https://github.com/jcurl/RJCP.DLL.SerialPortStream, export:

   export LD_LIBRARY_PATH="/path/to/serialportstream/lib:$LD_LIBRARY_PATH"

2. Load qcserial module:

   sudo modprobe qcserial

3. Find out Qualcomm device ID with lsusb (e.g. 05c6:9091)

4. Trigger new qcserial device with this ID:

   echo '05c6 9091' | sudo tee /sys/bus/usb-serial/drivers/qcserial/new_id

5. Find out which ttyUSB device is used:

   journalctl --since '1 h ago' | grep ttyUSB

6. Change port to that device (e.g. /dev/ttyUSB0) in EfsTools.dll.config

7. Run efstools:

   dotnet --roll-forward LatestMajor EfsTools.dll targetInfo
   Critical error. Error 5

Anyone ever got this to work in Linux?

[julumme]

Having same issue with ARCH. I built https://github.com/jcurl/serialportstream.git for the libnserial
and made sure that qcserial is the driver that handles ttyUSB1,2 and 3 (qcserial seems to refuse to handle ttyUSB0, which appears to be of "Bulk" type according to lsusb. Only the "option" driver seems to be willing to bind to it).

But none of those ttyUSB ports work - all die with same "Critical Error: Error 5"
