[U-Boot] [ANN] U-Boot v2017.05-rc2 released

[Tom Rini]

Hey all,

It's release day and v2017.05-rc2 is out.  I think my patchwork queue is
looking good currently.  I have some outstanding removal patches to take
from Masahiro related to architectures that I removed as promised.  The
release is bigger than I really wanted, but since I was on vacation for
most of the normal -rc1 window, stuff came in that would have come in
then now, instead.  Things are on track for -rc3 on the 1st.

Thanks all!

My weekly dfu test on the siemens smartweb board failed with
current HEAD.

I started an automated git bisect with tbot, and found:

     We don't want to claim that we support a serial number string and
     later return nothing. Because of that, if g_dnl_serial is an empty
     string, let's skip setting iSerialNumber to a valid number.

Is your board setting up the serial number with g_dnl_set_serialnumber()
correctly ?

Hmm.. good question ... its done here:

http://git.denx.de/?p=u-boot.git;a=blob;f=board/siemens/common/factoryset.c;h=6c869ed2b035a0e9f840e1f6f960fe0e6ac824e5;hb=f6c1df44b815a08585e7fd3805a1db51a5955d09#l313

but may this does not work correct and now pops up.

I try to find out more, thanks for the hint!

bye,
Heiko

Just check if you're not passing in NULL or empty string, that might be
it. Otherwise the USB code is botched.

Hmm... OK, on the smartweb board there is no factory set, so never
calling g_dnl_set_serialnumber()

:-(

why did this worked before commit 842778a091?

So, I added for a fast dirty test:

Now I see this printf:

Ok, before commit 842778a091 is in mainline I had the follwoing output:

# tb_ctrl: ./src/dfu-util -l

Found DFU: [0908:02d2] ver=0212, devnum=0, cfg=1, intf=0, alt=0,
	name="Linux", serial=""

serial is an empty string ... It seems to me, that commit 842778a091
broke here something fundamental ...

Hmm ... looking into drivers/usb/gadget/g_dnl.c g_dnl_bind()

if (strlen(g_dnl_serial)) {

is *before* g_dnl_bind_fixup() is called ... ?

Yup, with patch:

         ret = g_dnl_config_register(cdev);
         if (ret)
                 goto error;

and adding g_dnl_bind_fixup() in board/siemens/smartweb/smartweb.c
dfu work again for the smartweb board ... is this an valid fix?

BTW: is an empty serial string not allowed?

bye,
Heiko

This change was added recently to DFU tree. It seemed like the one,
which clean up things.

Moreover, I tested it on the "old" set of DFU tests (however, those
tests are not the USB compliance test suite).

Heiko, could you paste the error output? (from the host PC and the
board)?

This is Lukasz's domain of expertise, so I'll pull out of this

The problem is with providing "iSerialNumber" visible (at USB
descriptor) only when it is defined.

Before the Felipe commit (SHA1: 842778a091)  we had exposed it
unconditionally - even when we had a zeroed char table (which was the
"" string)

Now we do not have the iStringNumber field defined in descriptor when
the "serial" string size is zero.

I'm wondering which behavior is correct - i.e. comply with the USB
standard.

Felipe - have you tried to run the USB compliance tests [1] (Windows
one) after applying this patch?

[U-Boot] [ANN] U-Boot v2017.05-rc2 released

[Andreas Färber]

Hi,

Using -rc2 with firefly-rk3288 defconfig I can only boot into SPL but
not into full U-Boot. I am using the old documented way of dd'ing to
sector 256 on SD (doc/README.rockchip).

Looking at include/configs/rk3288_common.h I also tried putting
u-boot.img on a FAT partition, to no effect.

v2017.03 doesn't even show SPL working.
v2017.01 worked okay.

Build log for -rc2:
https://build.opensuse.org/build/Base:System:Staging/openSUSE_Factory_ARM/armv7l/u-boot-firefly-rk3288/_log

Andreas

Can you try removing RETURN_TO_BROM (or imilsar) and adding
CONFIG_SPL_OF_PLATDATA?

If that works we should probably create a new board variant with that
configuration, or figure out a way to detect which to use.

Simon

As an interim update I can share that latest master behaves slightly
differently:

U-Boot SPL 2017.05-rc2-00053-g3c476d8 (Apr 21 2017 - 02:29:48)
Returning to boot ROM...

compared to:

U-Boot SPL 2017.05-rc2 (Apr 20 2017 - 14:33:20)

Will tweak options next.

Thanks,
Andreas

Disabling the ROCKCHIP_SPL_BACK_TO_BROM option I get:

U-Boot SPL 2017.05-rc2-00053-g3c476d8 (Apr 21 2017 - 02:38:52)
SPL: Unsupported Boot Device!
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

If I additionally enable SPL_OF_PLATDATA then I am back to the v2017.03
state of no serial output.

Andreas

I just tested mainline with those two changes and it works for me. I
pushed my patch to u-boot-rockchip/firefly-working. Can you try again?

Confirming that with your defconfig it fully works again.

I had instead run menuconfig and manually (un)selected the options.
Maybe those options influence other defaults? I was at the same qoriq
merge commit your branch is based off.

Anyway, does this allow any conclusions for -rc3?

Cheers,
Andreas

... but enabling SPL_OF_PLATDATA and ROCKCHIP_SERIAL on master (via

Can you diff the resulting config? There might perhaps be a broken dependency.

Cutting a long thread short: U-Boot can only handle either BROM-style
booting or SPL-style booting. Since v2017.03 booting defaults to BROM,
which requires u-boot.bin immediately after the rksd, as opposed to
u-boot.img at sector 256 as before.

That works for -rc2, but still leaves v2017.03 without serial output.

Andreas

How to proceed here? If the current behaviour of U-Boot is correct,
then I simple adapt my tbot testcase ... but I think, currently we
have no way to set the serial number field, or?

However, IMHO it is better to not expose the string when it is empty.

:-( Yes, this commit has introduced regression (the g_dnl_serial is
always NULL there because we setup the serial number in a latter
function:

g_dnl_bind_fixup @ for example board/siemens/common/factoryreset.c

which calls: g_dnl_set_serialnumber() and only there the g_dnl_serial
is set.

Please find attached patch (if it fixes siemens boards).

sorry, I completely missed this.

if iSerialNumber is set to a non-zero value, then the actual string
should exist. if the string is empty, then iSerialNumber should be
cleared to zero in the device descriptor.
