imx6D uboot usb read issue

[jiujinhong]

Hi,

I met issue with USB R/W in bootloader. the program try to read 512M each, sometime it will fail with EHCI timeout, sometime it will success. I want to know if BSP pass USB large file R/W test or not.

If you can give some advice, please let me know, thanks.

Hi jiu

issue may be caused by communications problems due to

noise or weak signal. One can try tests described in I.MX6/7 Series USB Certification Guide

http://www.nxp.com/assets/documents/data/en/user-guides/IMXUSBCGUG.pdf 

USB layout in sect.3.12 USB recommendations i.MX6 System Development User’s Guide

Hi igor, i have imx6d/6q/6dl boards and made test in 6dl board, it is very stable. So, can you give some good advice?

[jiujinhong]

Hi Igor, this issue generated by U-boot otg driver, Linux OTG driver is very stable. I am very sure that fsl U-Boot 2015.04 BSP didn't test some large file READ/WRITE through usb otg.

[jiujinhong]

We are sure that fsl bsp has some issue to support USB R/W with large files.  In the beginning, we found that EHCI will timeout if read 64MB/128MB file. later, we applied patch from google, it can R/W successfully in most of time.

Hi Sir,

I need to suggestion for SW, not some others. It seems that this issue can be easily caused by some disk. Some udisk seems stable.
