Zedboard doesn't boot

Hi guys,

I've been working with a Zedboard for a couple of weeks now, and today stopped working, it doesn't boot anymore. When I turn the power on the "power led" goes on, but the blue led never turns on.

I've tried using the Out Of Box SD Card image and I've checked the jumper configuration as well. I know the problem is with this Zedboard because I've tried the SD Card image on another Zedboard and it worked fine.

Any ideas of what could be happening?

Thanks!

Hi Gary,

Thanks for your help! I followed the instructions on the ZedBoard Getting Started Guide and I was able to boot from QSPI Flash, I got the same led pattern as in the example.

Since your ZedBoard boots from QSPI Flash that seems to narrow down the problem to the SD Card boot. While it could be a problem with the ZedBoard SD interface, it is more likely the SD Card itself. Even though it does work on another ZedBoard, and did work earlier, it might be a marginal card. We have seen problems with some SD Card brands like Kingston. If you could copy the image to another SD Card and give it a try that could help determine the root of the problem.

I've tried booting with 3 different SD Cards and with different images (the OOB image and other one), still no results. I tested the 3 SD Cards on the other ZedBoard (the good one) and all 3 worked fine.

It sounds like a board problem then. You might visually inspect the SD Card socket and make sure there is no obvious issue. Otherwise, if your board purchase is within the warranty period, you can contact the organization you purchased the board from and request an RMA.

I was able to boot from QSPI Flash, as explained in the ZedBoard Configuration and Booting Guide (http://zedboard.org/design/1521/11).

To boot from QSPI I loaded a BOOT.BIN file from de SD Card into the QSPI Flash. After that I set the jumpers in QSPI mode and everything worked fine. This shows that the SD Card is working, I can read data from it.

I think the problem might be related to the boot ROM. Any ideas?

Thanks!

The QSPI boot file would have already been there unless you had erased or over written it. Copying the boot.bin from the SD Card to the QSPI Flash would not have worked. While boot.bin is the correct format for an SD Card boot file you have to generate a .mcs file type image for a QSPI boot and then use the Xilinx 'Program Flash' utility in SDK (or similar function) to write it to the QSPI Flash. You may have also noticed that the application booted from the QSPI was different than the one from the one on the SD Card.

The first time I booted from the QSPI the leds turned on in the same pattern as the Figure 28 of the ZedBoard Getting Started Guide.

After I followed the instructions on the ZedBoard Booting and Configuration Guide (pages 28-35) and booted again from the QSPI, the leds don't turn on anymore, but I got the GPIO Test Demo example going.

I don't know exactly how the QSPI booting process works, maybe I did something wrong, but I think I overwrited the content of the QSPI Flash with another boot image and it worked.

I'll try to boot from JTAG to see what happens.
