Zybo Support

[miwaxe]

Hi, i see Jamey Hicks added support for the Zybo board. It's it currently supported? I'm having problem booting it only flashing the output of "make all.zybo" from zynq-boot.

Thank you.

Yes, It should be working.
What type of problem are you seeing?

After power on and the USB plugged in, 2 usb tty devices are created;
the console is the 2nd device. On my mac, this is
/dev/tty.usbserial-00002026B .

After fsbl is done and before linux, you should see:
MAC Addr: 00 04 A3 D2 34 AC
Start clearreg
Jump to linux

Then, you should should see see the standard linux boot console
messages. If the output stalls after the lines:
mmc0: new high speed SDHC card at address 1234
mmcblk0: mmc0:1234 SA08G 7.21 GiB
mmcblk0: p1 p2 p3
Then it is waiting for a DHCP response on ethernet. The lines that
come directly after these in a normal boot are:
Sending DHCP requests ....xemacps e000b000.eth: Set clk to 25000000 Hz
xemacps e000b000.eth: link up (100/FULL)

After that, linux just trundles along until you get to a console
prompt (you have to hit 'enter' to actually get the prompt to appear).

On other point... When I have connected ethernet to 1 gigabit
ethernet switch, the xilinx driver fails to correctly bring up the
link. In these cases I have just put a 100Mbps ethernet switch in
between and it has booted without problems.

At which stage are you having problems?

Hi,

I suggest trying prebuilt zynq-boot images. The current version is here:

It doesn't even arrive to load the boot.bin even though i can read/mount the sdcard if i boot from QSPI. I'm currently thinking it's a faulty one or, maybe, i do something wrong formatting the sdcard.

[Jamey Hicks]

There are a number of factors that might cause a problem with the FSBL.

I think all of our cards are formatted to have a single partition, and that partition has a VFAT or MSDOS filesystem on it. You can have multiple partitions on the card, but FSBL will look at the first one and it has to be VFAT or MSDOS.

I remember we had problems if there was no partition table, but I do not remember the details.

There may also be a limit on the capacity of the card. SD and SDHC definitely work, but I do not know if the FSBL can read SDXC. SDXC is cards holding more than 32GB.

[miwaxe]

I tried with another sdhc (4GB - Kodak) and the zybo boot. Meanwhile the first SD (1GB - Kingston) non hc continues not to be viewed at boot, while Linux in QSPI could read/write/mount it without problem, really strange bug.

[Jamey Hicks]

I'm glad to hear that the Kodak card boots.

It is a good idea to try multiple SD cards when there are problems. Some of them just do not behave very well. I think I have had trouble with Kingston cards in the past, so I no longer buy them.
