SD Card boot problem

Hi everyone,

I'm using a Avnet ZedBoard with Zynq-7000 AP SoC /Analog Devices Software-Defined Radio kit. My work is to program the full SDR in VHDL.

The included SD Card is a 256 MB Sandisk card (it runs perfectly with Linaro Ubuntu OS). I would like to run the OS with a 8GB Sandisk Card but it failed.

I have copied the same files to the root of the BOOT FAT32 partition.The Linux kernel uImage is the same for all targets.

Anyone with any ideas on what might be wrong?

Thanks

Hi,
Zedboard ships with a 4 GB SD card, so I'm not sure where the 256 MB card came from. However, the Ubuntu system does run without issues from various 8 GB cards, and Sandisk is one of the most reliable. You don't say how the system fails, so providing some details would be helpful in the remote diagnosis.
How did you create the ext4 partition for the root file system on the 8 GB card?

Hi Ron. Thanks for helping!

The 256MB card came from the Avnet kit. It was included with the full SoC kit.

When I try to boot the Ubuntu OS, the display freezes. I think it doesn't run the boot (not starting the Kernel), I can only see 2 Ubuntu penguins on the display.

I'm using a SD Card reader from Windows 8 on my own laptop.

I have copied target/BOOT.BIN and target/devicetree.dtb to the root of the BOOT FAT32 partition. It works perfectly with the 256MB SD Card.

I have followed the Getting Started Guide mentionning this link :

http://wiki.analog.com/resources/tools-software/linux-software/zynq_images.

I saw it this morning, it may be the cause? "We have heard of some versions of Windows, and some specific SD readers/writers that don't like the FAT parition that we make on the SD Cards - sorry - we have no idea, and have no way to replicate things (that we have found). If it doesn't work for you - try a different windows machine."

Could you please give me more information about ext4 partition?

I'm available by mail (beouche.k@gmail.com) if you need any screenshot for helping.

Thanks a lot!

Kind Regards,

Karim

Karim,
Have you looked at the Ubuntu tutorial document on this website? It expands on the brief information available in the Analog Wiki. If you look at the one for the Zynq Mini-ITX, it is more recent and the sections about the ext4 file system are common anyway.
If that doesn't work, we can try using a known-good 8GB Sandisk image to eliminate problems such as the Windows machine. I myself haven't tried any of this from Windows 8; I'm still at Windows 7.
