Recovery mode: Ubuntu 14.04 does not find the Apalis TK1 as USB device

I tried to get access on the Apalis TK1 via USB during recovery mode like described here: Txx recovery mode. I verified the recovery mode by checking the usb devices (~ “NVIDIA USB Boot-recovery driver for Mobile devices” in the Windows instructions):

~$ lsusb
...
Bus 001 Device 015: ID 0955:7740 NVidia Corp.
...

However the device does not show up in the list of devices in the host. Listing devices without running the board and running the board in recovery mode does not show any differences:

~$ ls /dev/ grep sd

The issue could be related with this question.

I am a little bit confused about your mentioning Windows instructions. What exactly is it that you would like to do?

Maybe you should just have a look at the following article on our developer website.

But doesn’t your lsusb show it just fine?

I am really unsure as to what exactly you would expect that ls /dev/ grep sd be doing for you. At the least you would need a pipe symbol before the grep part. But please note that the NVIDIA USB recovery mode has absolutely nothing to do with any USB mass storage aka sd devices. The only thing able to talk to a device in USB recovery mode is tegrarcm which is what our ./update.sh -d will be using. Again I am unclear as to what exactly you are trying to do.

The issue could be related with this question.

Even in that question there wasn’t really any issue as it worked for that customer just fine.

You are right. I was able to trigger the image flashing from within the recovery mode with run setupdate and run update_uboot. (I used TFTP for image transmission.)
