Boot from USB hangs at message: Waiting for root device /dev/sda2...

Tim Dicke

Background:

Custom board
Processor: AM4379BZDNA100
Linux distro: TI PROCESSOR-SDK-LINUX-AM437X v2.00.00.00 (Linux v4.1.6)
Main com port: UART1
Boot mode[4:0]: 10100b MMC0, USB_MS(USB1), USB_CL(USB0), MMC1
UniFlash: Running on Win7 PC
Linux build environment: Ubuntu 14.04.1 VM

Situation:

Booting custom board from a USB stick progresses until the following message appears:

[ 1.659320] Waiting for root device /dev/sda2...

USB stick was generated to produce a 2 partition file system using the script create-sdcard.sh.

I have referenced the following threads and assume at this point is has something to do with my kernel configuration (attached below). Boot messages are also attached below.

# CONFIG_USB_MASS_STORAGE is not set

seems wrong. You likely want it compiled in because you don't want it to be a module (can't load it if you can't mount root).

Got that one set now. Still no joy... New config attached.

The boot log is more useful. Basically, it doesn't look like it's even reading the partition table from the USB stick. There should be messages to that effect.

0 Tim Dicke over 9 years ago in reply to Matthew Caron

Intellectual 370 points

I don't think it's far enough along to create a boot log file. The USB stick LED shows activity when U-boot is accessing it but when the kernel is getting started it stays dark.

0 Matthew Caron over 9 years ago in reply to Tim Dicke

I mean the boot messages that come out the terminal - the one you attached earlier as bootmsgs1.txt.

Now, that said, it may or may not be different.

It looks pretty much the same except for slight changes in time stamps...

Is CONFIG_USB_STORAGE still a module? That may need to change to y as well.

What you're looking for, BTW, is output like this:

I already got that one updated to 'y'. Still no joy. My current, updated config is below.

I gathered the output should look something like what you've shown from some of the other threads I've reviewed. It doesn't seem to be detecting the USB stick in the kernel or even the root device for that matter.

Your time stamps are awfully high in value. Do you have any extra debug messages active to see these? I have all the extra stuff turned off right now. Just standard boot messages from the kernel.

Yeah, it's not detecting the USB stick.

Ignore my timestamps - they're from my desktop.

Regarding other stuff - these are admittedly grasping.

I do notice that CONFIG_USB_XHCI_PLATFORM is a module, as are CONFIG_USB_F_MASS_STORAGE and CONFIG_USB_MASS_STORAGE. I don't know about the first two, but I'm pretty sure the latter needs to be =y.

I did not try usb host boot, but please ensure the following configs are 'y' to enable usb in am437x kernel.

CONFIG_USB_DWC3

CONFIG_USB_DWC3_DUAL_ROLE

CONFIG_USB_OTG <--- required for DRD mode

CONFIG_USB_DWC3_OMAP

CONFIG_USB_XHCI_HCD

CONFIG_USB_XHCI_PLATFORM

CONFIG_OMAP_CONTROL_PHY

CONFIG_OMAP_USB2

You don't need to enable CONFIG_USB_F_MASS_STORAGE, which is for gadget mode support.

Thanks for the suggestions Bin!

I have updated all the configs you recommended to 'y' settings. It still does not appear to be detecting the USB stick (no light on the USB stick). I have attached my updated config file in case you need to double-check. I also have the boot messages included below.

I forgot to update CONFIG_USB_MASS_STORAGE to 'y' in the previous updates recommended by Bin. I just added that one too and same results. No significant changes in the messages that I can see.

Latest config file attached:

Tim,

The kernel boot log does not have any message related to xhci, so the xhci related drivers are not loaded at all. Please let me try to boot from usb on my am437x evm, then we know what kernel config should be.

Tim,

Attached below is my .config for usb host boot.

_config.usbboot.txt

And following is the change I made based on omap2plus-defconfig to enable usb host boot. It seems the only thing missing in yours is CONFIG_USB_DWC3_HOST=y instead of CONFIG_USB_DWC3_DUAL_ROLE=y.

Thanks again Bin.

I changed my config file as you instructed (CONFIG_USB_DWC3_DUAL_ROLE=y to CONFIG_USB_DWC3_HOST=y) but it still does not recognize the USB stick. Is there anything that needs to be done with the dts file?

I think we are getting pretty close. I have just been able to successfully boot my board from emmc. Even under linux I don't have any joy with the USB stick being recognized.
