Drive PX2 in recovery mode cannot been detected by sdkmanager

Hi Team,

I am trying to reflash the PX2 p2379. I set it into recovery mode using minicom. And then sdkmanager detects it as Jetson TX2i instead of PX2 p2379. I tried on sdkmanager 1.4/1.3/1.2/1.1, they all detect the px2 board as Jetson TX2i.

More information:
when I close the recovery mode, the px2 board can be detected correctly.

I also tried on Ubuntu18.04 and 16.04, it is the same issue.

When I enter sdkmanager, the default detected board is Jetson TX2i. Also, when I choose Drive PX2 P2379, a notice is shown:

Dear @baofu.wu,
Can you keep the board in normal mode and check flashing using sdkmanager? do you see any issue with flashing?

Dear @SivaRamaKrishnaNV,
Thank you for your reply! And the following is the issue with flashing in normal mode.

Dear @baofu.wu,
It seems the serial connection to aurix is not closed before flashing. I could see /var/lock/LCK…ttyUSB1 is already used by another process in the logs. Could you check that?

It works! Thank you very much!

The steps I did are as follows:

  1. keep the board in normal mode, DO NOT enter into recovery mode;
  2. I uninstall all DRIVE OS 5.0.10.3 SDK WITH DRIVE … and TARGET COMPONENTS(DRIVE PX2 AUTOCHAUFFEUR) softwares in the SDK Manager STEP 01;
  3. Release serial connection, easpecillly, /dev/ttyUSB1,/dev/ttyUSB2 and /dev/ttyUSB6.(I closed all minicom terminals.)
  4. flashing
