A working boot image (SD card and TFTP) would be very useful in the near future (let's say 1-2 weeks).

Thanks,
Herbert

@Bertl Do you have a 7020?

Bertl added a comment.Nov 14 2014, 8:53 PM

will test on the 7020 MicroZed ASAP.

After a long search for a _working_ SD card reader/writer (I have now three non working adapters) I'm now finally ready to do some testing.

First impression (testing with the 7010 MicroZed):

this is after unpacking apertus-boot.tar.bz2 and moving the boot content to a 256MB VFAT partitioned SD card.
please advise what I'm seeing here.

fatload mmc 0 0x3000000 uImage
fatload mmc 0 0x2A00000 devicetree.dtb
setenv bootargs console=ttyPS0,115200n8 root=/dev/mmcblk0p2 rw rootdelay=2 init=/usr/lib/systemd/systemd

Lets see if that works ;)

I presume I should put a rootfs on partition 2, yes?

skinkie added a comment.Nov 25 2014, 8:49 PM

My suggestion was to take the ArchLinux ZedBoard image, and add our bootpart for the 7010 board. I guess given I see a kernel booting. We don't have any problems with the 7020 :-)

Bertl added a comment.Nov 27 2014, 2:29 AM

something strange is going on.

I added an uEnv.txt with:

kernel_image=uImage.bin
devicetree_image=devicetree.dtb
ramdisk_image=uramdisk.image.gz
bootargs="console=ttyPS0,115200n8 root=/dev/mmcblk0p2 rw rootdelay=5 init=/usr/lib/systemd/systemd"
uenvcmd=run myboot || bootm 0x3000000 - 0x2A00000

but the rootdelay=5 is ignored and the boot fails:

Forgot to mention, behaviour is the same on the 7020 MicroZed.

Bertl renamed this task from Get the image working for the 7020 MicroZed. to Get the image working for the MicroZed (7010 and 7020)..Nov 29 2014, 3:30 AM
Bertl updated the task description. (Show Details)
Bertl reassigned this task from Bertl to skinkie.
skinkie added a comment.Nov 29 2014, 12:17 PM

Ok, enough information. I'll make an all in one image.

Bertl added a comment.Dec 16 2014, 4:19 PM

Any news on this?

I'd love to have an image which actually boots up automatically and doesn't require human interaction.

Best,
Herbert

skinkie added a comment.Dec 16 2014, 4:32 PM

I have asked Sven if we could directly migrate to the Elphel bootloader code, he was investigating it. But I haven't heard from him, so I contacted him on Sunday about it. Obviously I can upgrade the existing image to something like a 2GB partition and go with that, but I was hoping for "more".

skinkie added a comment.Dec 18 2014, 11:07 PM

It would be greatly appreciated if someone could take a peak if the following image will work on a vanilla MicroZed.

When manually booting with bootm 0x3000000 - 0x2A00000 it boots up to a certain point where it simply resets.

The point where it resets is not deterministic.

try #1 [ OK ] Started udev Coldplug all Devices.
try #2 [ OK ] Started udev Kernel Device Manager.
try #3 [ OK ] Started Flush Journal to Persistent Storage.

I'm now going to check with the previous image if that might be hardware related.

Bertl added a comment.Dec 26 2014, 5:45 PM

Problem seems to be power consumption related.
I got it to boot after applying additional power (i.e. the USB power is insufficient).

The image draws significantly more power than the previous one, the Zynq also heats up significantly when everything is idle.
I don't have specifics as the xadc interface seems to be non-functional (so no temperature/voltage measurements).

skinkie added a comment.Dec 26 2014, 8:34 PM

Is this on the 7020?

skinkie added a comment.Dec 29 2014, 2:16 PM

So what has changed between the last and this revision? Mainly the automatic starting of the ethernet interface and run DHCP.

skinkie added a comment.Dec 29 2014, 2:17 PM

But what I was more interested about: does the image "autoboot"?

Bertl added a comment.Dec 31 2014, 2:14 AM

no, it doesn't because it seems to execute the wrong script.

see my first response.

skinkie added a comment.Dec 31 2014, 2:27 AM

What would be the best way to 'clear' my configuration so I can observe the behavior you are having? You did select the dipswitch of booting from SD?

Bertl added a comment.Jan 10 2015, 1:37 AM

We should really move that to a faster medium, please ping me on IRC in the future if you need to know something to avoid further delays.

Jumper settings are:
JP3 2-3
JP2 2-3
JP1 1-2

I can probably upload a dump of all on-board memories.

Bertl added a comment.Jan 10 2015, 1:58 AM

QSPI is not accessible under linux with the image:
[ 0.746324] zynq-qspi e000d000.ps7-qspi: pclk clock not found.
[ 0.750826] zynq-qspi: probe of e000d000.ps7-qspi failed with error -2

But if it helps, I can try to dump it from u-boot.

skinkie added a comment.Jan 10 2015, 2:26 AM

So first of all, the uenv.txt issue will be solved by the description Sven gave. Needs a recompiled u-boot, we can handle that.

Regarding the qspi, i'll investigate if the 7010 has issues with it as well. But after that I need to investigate why the Xilinx stock settings are wrong.

Bertl added a comment.Jan 10 2015, 8:35 AM

I rolled my own devicetree for the ZedBoard, it might make sense to do so for the MicroZed as well.
Also some devices will not be required in the kernels (because the hardware is not there) and others might need to be enabled (because the default is to disable them)

Thanks in advance,
Herbert

skinkie added a comment.Jan 19 2015, 12:55 AM

Status: the current only problem with the current compilation of u-boot seems to be that the uenv.txt is not loaded by default. It did require a minor change to the uenv.txt.

The device has the following stock configuration:

"uenvboot=" \
        "if run loadbootenv; then " \
                "echo Loaded environment from ${bootenv}; " \
                "run importbootenv; " \
        "fi; " \
        "if test -n $uenvcmd; then " \
                "echo Running uenvcmd ...; " \
                "run uenvcmd; " \
        "fi\0" \
"sdboot=if mmcinfo; then " \
                "run uenvboot; " \
                "echo Copying Linux from SD to RAM... && " \
                "fatload mmc 0 0x3000000 ${kernel_image} && " \
                "fatload mmc 0 0x2A00000 ${devicetree_image} && " \
                "fatload mmc 0 0x2000000 ${ramdisk_image} && " \
                "bootm 0x3000000 0x2000000 0x2A00000; " \
        "fi\0" \

Obviously this all makes sense because it doesn't "run" the sdboot from the uenv thingie, but it runs the fatload the current configuration.

  1. Run saveenv, so at least the reboot functions.
  2. Rewrite sdboot it calls itself a second time with loop prevention(?)
  3. Add an empty ramdisk image.

My preference (as stated on IRC):

Have a cleaned up default environment in our uboot.
By default, source the uenv.txt from SD and if successfull, run uenvboot (or axiomboot)

Any progress here?
Can we expect something in the near future?

I'm asking because I need a working bootloader and kernel for testing and if this needs much more time on your side, I'm going to build/config my own for this purpose.

Thanks,
Herbert

Yes. Expect an update of the image and uboot this evening.

New boot.bin for testing.

http://stefan.konink.de/contrib/apertus/boot.bin

Known issues:
QSPI not being detected.

skinkie added a comment.Feb 12 2015, 9:14 PM

Update to boot.bin to kernel 3.14. XADC has been added. QSPI still not detected.

u-boot seems to have a problem with modified MAC addresses.

setenv ethaddr 00:0a:35:00:01:22
bootp

works fine, but

setenv ethaddr 00:0a:35:00:01:23
bootp

fails with:

Retry count exceeded

although the dhcp server hands out a proper IP.

Bertl added a comment.Mar 14 2015, 11:45 PM

btw, where can I find/get the kernel/u-boot sources you used?

skinkie added a comment.Mar 14 2015, 11:46 PM

If we remove the ethaddr option, will it be recovered by Linux when the PHY is setup?

skinkie added a comment.Mar 15 2015, 12:07 AM

Just send you an email on the sources topic.

Bertl added a comment.Mar 15 2015, 12:21 AM

It seems, u-boot doesn't update the GEM registers.

The following manual GEM modification makes it work (for the :23 MAC address):

mw.l 0xE000B08C 0x2301
Bertl added a comment.Mar 15 2015, 12:38 AM

What happens is that the GEM is initialized with the u-boot hard coded MAC address, and changing the etheraddr later in uEnv.txt does indeed change the u-boot generated packets, but it doesn't update (or reinitialize) the GEM, so it still only receives packets for the hardcoded MAC.

QSPI works with the correct devicetree entry.

note that I do not have your devicetree.dts, so this is from the decompiled devicetree.dtb.

u-boot networking is still a big problem, especially for TFTP based boot.

It seems that there is roughly a 30% chance that there is a timeout when the PHY is reset:

Gem.e000b000:0 is connected to Gem.e000b000.  Reconnecting to Gem.e000b000
Gem.e000b000 Waiting for PHY auto negotiation to complete......... TIMEOUT !
Gem.e000b000: No link.

Unfortunately, this u-boot version resets the PHY on every TFTP request, so if you load three files (kernel, initramfs, devicetree), then your chances to get all of them without a timeout are minimal.

I know that I switched to the digilent branch of u-boot for the alpha because of this annoying, time consuming, issue.

Do tell, how did you get a working devicetree if the thing is entirely generated out of broken software?

Bertl added a comment.Mar 16 2015, 1:28 PM

Back for the alpha I started writing my own devicetree and I simply copied the relevant part from there (adjusting to the decompiled devicetree of course).

IMHO it makes a lot of sense to write a clean devicetree ourselves, as both the xilinx and the digilent version is somewhat broken and/or contains unnecessary definitions (like for xilinx/digilent IP cores).

My proposal would be to start one for the MicroZed and keep it up-to-date in git (on github). I can provide an initial version which probably needs a few minor updates.
