[U-Boot] Rpi Uboot not working ; USB keyboard undetected

[U-Boot] Rpi Uboot not working ; USB keyboard undetected

[Sumeet Jauhar]

Hello All,

I am new to Rpi and for a project I need to install Uboot for Rpi. For starters I installed Raspbian-jessie to the pi and it worked fine. Now I am attempting to use uboot but I don't succeed. I am trying to follow the instructions http://elinux.org/RPi_U-Boot  and http://arrizza.org/wiki/index.php/RPI_U-boot . Here is what i have done so far.

1) Downloaded and compiled the code from "Stephen Warren's work-in-progress branch"  (and also from the mainline when the former did not work). I used a Debian box to compile and and used CROSS_COMPILE=arm-linux-gnueabi- . I am able to successfully build uboot.bin

2) Now I copy uboot.bin to the SD card. I replace the config.txt to have a line kernel=uboot.bin . ( I also tried to replace the kernel.bin directly as uboot.bin)

Now when I boot the pi I stop at the uboot prompt but my USB keyboard and USB mouse are not recognized . I can't do anything ! How do I communicate with the pi ??

My question seems similar to https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=104383 but I see no fix for the problem.

I am attaching an image of the bootup so maybe you guys can point the error ..

In fact I tried each of the branches ; mainline ; Stephen Warren and also Olex's branch. Olex branch seems to have USB support but it does not work for me . I get a different error now .

Saying the "Unrecognized filesystem type **"

Any clues how to go about fixing this ?

There seems to be a problem with the RPi and USB Low-speed and Full-speed 
devices. The following did work (480Mbps capable):

- several USB memory sticks
- USB 3.0/2.0 SDHC card reader
- RTL2832u based DVB-T stick
- Haupage PCTV 290e DVB-T2 stick

Following did not work:
- several mice/keyboards (12Mbps/1.5Mbps)
- several USB/serial adapters
  * PL2303 (12Mbps)
  * Cypress CYC765211 (12Mbps)
- USB audio noname device (12Mbps)

Kind regards,

Stefan

Hmm, I'm not familiar with the rpi usb controller, but AFAIK the rpi uses
an onboard usb-2 hub, when talking to usb-1 devices attached to a usb-2
hub you must address the tt in the first usb-2 hub upstream of the
usb-1 device. See e.g.:

http://git.denx.de/?p=u-boot.git;a=commitdiff;h=4e2c4ad3604ba6f5053090749d64ed3ce5914805
http://git.denx.de/?p=u-boot.git;a=commitdiff;h=fcdd8aaa48dfcac492cbac5436d9edc3f5928325

And also, for a controller which AFAICT is closer to the rpi usb controller:

http://git.denx.de/?p=u-boot.git;a=commitdiff;h=e740ca3cab93a8cb31d870bffecd6aa8eadf44e1

Note that the last 2 commits both do a bunch of magic to translate from usb_device
pointers to dm device pointers and back, not sure if the rpi usb controller code
has been converted to dm yet, but if it has that is a likely culprit.

I hope this helps.

Regards,

Hans

Yes, LS/FS devices probably won't work.

If you attach an LS/FS device directly to the bcm2835 USB controller,
they should work fine with recent versions of U-Boot. This is possible
with a RPi model A.

However, with an RPi model B, there is an integrated USB hub which runs
at HS. This requires "split transactions" to be implemented by the USB
host controller in order to communicate with an LS/FS device. This is
not yet implemented in the U-Boot driver for this HW.

Yes, thats true for RPi 1 B, B+ and RPi 2 B.

Most of the DWC2 code is agnostic to DM vs. legacy. The biggest problem is the 
fact that on the DWC2 both SSPLIT and CSPLIT have to be handled explicitly, 
i.e. there is an ACK interrupt after the SSPLIT and the channel is halted, and 
you get another ACK/CHHLT/XFERCOMPL interrupt after the CSPLIT transaction.

I have some rough prototype code which is at least able to enumerate most of 
my LS/FS devices. There are errors for some devices, which are picky about 
some SETUP requests.

Kind regards,

Stefan
