Edited: Cannot boot Zedboard from the 13020600 image

[mipt98]

Edited:

Dear All, please help
Cannot boot Zedboard with 64-core Epiphany using zedboard_parallella_64_13020600.img It continues printing something like

detect: f0 1 0 0
detect: f0 1 0 0
* * *
or

detect: 90 2 0 3
detect: 90 2 0 3
* * *

if Epiphany board is not connected and doesn't go any further. The boot messages are below. I have no idea what causes the trouble, and will highly appreciate any input. One thing is that it doesn't seem to be an SD issue. I wrote the Zedboard image that came with the board to the same 32gb SD and the board booted without problems.

[mipt98]

Could anybody post their boot log? Thanks!

[aolofsson]

Ivan,

I haven't seen this before, maybe others have had similar problems and can assist?

Just to summarize the burn and boot process that is the most thoroughly tested so far:

1.) For the 64-core board grab this file.
ftp://ftp.parallella.org/parallella/sd_ ... 020600.zip

2.) Use a 8GB or 16GB card SDHC card like the following:
http://www.amazon.com/SanDisk-MicroSDHC ... 695&sr=1-2

3.) Use the win32diskimager to write the image to the sd card. (I am sure you can do it in Linux, but this is what we started with..)
http://sourceforge.net/projects/win32di ... t/download

4.) Make sure the Epiphany FMC card is plugged in at boot.

5.) Read the quick start guide here, make sure all the jumpers are in the correct positions!
https://github.com/adapteva/epiphany-li ... _guide.pdf

6.) If for some reason the board still has issues, it might be a uart or hdmi issue? Try hooking up the ethernet cable only and see if the machine comes up on the network...sorry for asking you to try this.

I went through all the steps but still struggling with the boot process and eager to see a successful boot log...

I have one suggestion. Currently, the kernel launch parameters are hardcoded in the device tree. It would be great to expose them to U-boot environment in order to be able to quickly modify them. For instance, I would like to try to mount the root fs to RAM and see what will happen, but can't do it without recompiling the tree. Apparently a standard way of doing it is to
$ setenv bootargs '<args>'; boot
However it seems that the hardcoded parameters take precedence over the environment settings.

First good news in the last several days. I was blaming the SD detect feature, thought maybe it was a hardware problem, bad pin or something. So decided to disable the card detect in the kernel (make it always be true), but first simply compiled the kernel from gen0 in https://github.com/parallella/parallella-linux. And this new kernel booted. Presumably there was some sort of mismatch between the zedboard I have and the kernel on the FTP site.

Still things look glitchy: getting different boot messages from time to time. Sometimes I get errors. For instance, first I can get these
Freeing init memory: 152K
* Starting mDNS/DNS-SD daemon [ OK ]
* Starting Bridge udev events into upstart [ OK ]
* Starting network connection manager [ OK ]
* Starting Bridge udev events into upstart [ OK ]
* Starting Bridge udev events into upstart [ OK ]
* Stopping cold plug devices [ OK ]
* Stopping log initial device creation [ OK ]
* Starting load fallback graphics devices [ OK ]
* Starting configure virtual network devices [ OK ]
* Starting load fallback graphics devices [fail]
* Starting configure network device security [ OK ]
* Starting Userspace bootsplash [ OK ]

and at the next boot I see the following
Freeing init memory: 152K
modprobe: FATAL: Could not load /lib/modules/3.6.0-xilinx/modules.dep: No such file or directory

modprobe: FATAL: Could not load /lib/modules/3.6.0-xilinx/modules.dep: No such file or directory

* Starting Bridge udev events into upstart [ OK ]
* Stopping cold plug devices [ OK ]

* Starting load fallback graphics devices [fail]


Does it look normal or not?

Ivan,

That's great news! What you are seeing is the result of a know anomaly in the E64 chip. There is an errata (documented in the datasheet) that limits fetching instructions and loading data (LDR) from DRAM to row-2. Using DMA to bring in data on that row works fine. This is unfortunate, but in many programs workarounds to this issue are ok.

With respect to the matmul, this is likely due to an old example. I recommend installing the latest SDK. viewtopic.php?f=13&t=422
