USB issue on i.MX6DL

dinochang — Fri, 17 Jun 2016 12:17:34 GMT

Hi community,

We are working on our custom i.MX6DL board, but now we meet a strange issue for USB.

On our custom board, USB host port connect to 3G modem, USB OTG force to host mode, and connect with a external USB camera.

Our kernel version is 3.14.52 and our operating system is Debian Jessie. When we use wvdial to connect to internet, it works normally, we can get ip address, but when we use ping to test, we found a strange behavior. If we don't specify packet size, it work normally, but when we specify icmp packet size to 1400bytes, we got packet lost.

On OTG port, when we connect a standard notebook camera, we can record and play video correct. But if we connect elp -usbfhd01m-dl36 (3.6mm lens) digital camera usb cctv camera , when we try to record vider, console appear "v4l2: oops: select timeouts" error message.

We had check our hardware, eye diagram is fine, USB voltage is correct...now we can't finger out what happen.

Could you give some suggestion? Thanks.

Hi Dino

weid behaviour may be caused ddr errors so one can try to run ddr test

The DDR stress test can run with an incrementing frequency or at a static freq

To run at a static freq, simply set the start freq and end freq to the same value

Would you like to run the DDR Stress Test (y/n)?

Enter desired START freq (135 to 672 MHz), then hit enter.

Note: DDR3 minimum is ~333MHz, do not recommend to go too much below this.

The freq you entered was: 390

Enter desired END freq (135 to 672 MHz), then hit enter.

Make sure this is equal to or greater than start freq

Hi Dino

had you rebuilt uboot with new calibration settings obtained from ddr test ?

Also could you try with Demo Images

Hi Igor,

I had rebuilt uboot with new calibration settings, but still doesn't wok normally.

Does that mean if we can pass stress test, but see some test fail when read/write calibrate, our DDR settings is correct?

Re: USB issue on i.MX6DL

igorpadykov — Mon, 20 Jun 2016 00:12:31 GMT

Hi Dino

memory read/write data tests should pass well with correct DDR settings.

Also it could be ripple problem, as ddr tester does not stress well all board power supplies,

one can check that hand soldering 22uF capacitors directly under center of chip

and increase voltages of ARM_CAP, SOC_CAP, PU_CAP.

Hi Dino

could you try to run minimal image, refer to attached Yocto Guide Table 1, use below sources

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-imx?h=imx_3.14.52_1.1.0_ga

Hi Igor,

We had solved the problem, the root cause is our DDR layout is wrong.

After change bootloader and memory size to 256MB, everything work normally.

Thanks for your helping.

Best regards,

Dino
