A request about I.MX6 series USB Certification

xiangqian · ‎10-01-2017

Hi NXP,

We have worked on IMX6 platform with Android 6.0 based on Kernel 4.1.5. We need to pass USB-IF Certification.

From a guides as below, we can output Test packet for eye diagram test by using memtool without PID/VID Test Fixture. It looks the eye diagram is fine in open keysight laboratory.
memtool 0x2184184=0x18441205 // Force to output Test Packet for Eye Diagram Test

https://community.nxp.com/docs/DOC-105609

But USB cerification needs 8 items to test as below:

VID PID

0x1A0A       0x0101 /* Test_SE0_NAK */
0x1A0A       0x0102 /* Test_J */
0x1A0A       0x0103 /* Test_K */
0x1A0A       0x0104 /* Test_Packet */
0x1A0A       0x0106 /* HS_HOST_PORT_SUSPEND_RESUME */
0x1A0A       0x0107 /* SINGLE_STEP_GET_DEV_DESC */
0x1A0A       0x0108 /* SINGLE_STEP_GET_DEV_DESC_DATA */
0x1A0A       0x0200 /* TEST_OTG_TEST_DEVICE_SUPPORT*/

For 0x0106/0x0107/0x0108/0x0200 , could you give their commands or method ?

If I want to write USB PHY register in kernel driver, I only set USBC_n_PORTSC1 register ? write what value ?

what register shall I write for the commands as below?

memtool 0x2184384=0x18001305      // Force to output Reset
memtool 0x2184384=0x18001285      //Ho Force to output Suspend
memtool 0x2184384=0x18001245      // Force to output Resume

Could you help us and give a sample ?

Thanks a lot.

Hi Xiang

for that values one can look at sdk/drivers/usb/test/usb0_host_testmodes_test.c

Github SDK
