Boot kernel and filesystem from u-boot-2013

[manjunathjoshi]

Hello All,

I have configured the u-boot 2013.04 to detect USB at u-boot. I am getting the following logs,

U-Boot > usb start

(Re)start USB...

USB0:   USB EHCI 1.00

scanning bus 0 for devices... 1 USB Device(s) found

       scanning usb for storage devices... 0 Storage Device(s) found

       scanning usb for ethernet devices... 0 Ethernet Device(s) found

Even though there is a USB i can't access it. Please let me know if anybody has had this issue and please reply ASAP.

The most important thing is this port is USB OTG.

Hello All,

The issue was power sequence in module in which PMIC PFUZE100 chip had to be powered on (connected by i2c lines), before checking for USB.

It is purely power issue. If power is not proper to USB, the above issue arises. that is the reason why i never faced the above problem when i did a soft "reboot" but on hard power off and on this issue was seen every time.

That was my final conclusion. Thank you all for helping out. Specially igorpadykov.

Regards,

Manju

Hello Igor,

This issue is not solved.

I have tried using debug prints and below are the logs,

Hello All,

I am consistently getting this ehci timeout error. I googled a lot and i found that this is a bug from u-boot. Is there any patch that solves this issue?

I can't migrate to newer version since u-boot has some other changes as well which would be time consuming.

Regards,

Manju

[igorpadykov]

one can post it to uboot mail list

U-Boot Info Page

or use newer uboot versions

Hi Manjunath

there are other commands which could be used, as:

usb start

fatls usb 0:1

fatload usb 0:1 0x80800000 filename

usb read 0x80800000 0 10

for details please refer to descriptions on p.22 document
