Question, i.MX6Q USB complaint test

Aemj — Wed, 12 Oct 2016 05:50:14 GMT

Dear team,

My customer is trying to handle USB module of i.MX6Q-SABRE for the preparation of USB certification test.

Referring to the following community thread, they are trying to execute the memtool commands.

https://community.nxp.com/thread/383925

When they executed the commands, i.MX6Q stopped as below.

$ root@imx6qsabresd:~# /unit_tests/memtool 0x2184184=0x18411205

$ Writing 32-bit value 0x18411205 t

The environment is as below.

OS: LinuxBSP(3.14.28)

Board: i.MX6Q-SABRE

Please find the attached file for the board connection.

Do you have any ideas about the cause of this issue?

Thanks,

Miyamoto

Hello,

From the original thread https://community.nxp.com/thread/383925

"Use memtool to set the USB PHY registers Port Status & Control (USBC_n_PORTSC1)
directly to output the specified pattern, make sure a HS device is connected to DUT before setting,

otherwise system might crash."

Have a great day,

Yuri
