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
