DONE LED fails to light on PicoZed 7015 and 7030 out-of-the-box

PicoZed 7015 and 7030 SOMs manufactured with Serial Numbers less than or equal to the numbers below had an error in the image that got installed into the Flash. This error causes the SOM boot to stall after U-boot loads. This means that the bitstream does not get configured into the PL, so the blue DONE LED does not light. Additionally, booting to Linux does not happen.

BD-Z7PZP-7Z030-G REV C01 Serial 1412248

 

This is no way affects the quality of the boards, as they had to complete a full functional test before leaving the factory. You can verify that your board is in expected condition by checking the output on the USB-UART terminal:

We apologize for this issue. An upgraded version of the Avnet Flash image is described in this forum post, or you may freely reprogram the QSPI with your own image.

One more note -- you can also

One more note -- you can also use the pre-built image inside the PetaLinux BSP. This gives you the added advantage of having an archive of the hardware platform in a more recent Vivado version. The BSP archive is a zip file – for example Avnet-PicoZed-7z030-v2014.4.zip
 - When unzipped, you find archive pz_7z030.bsp
 - This file can also be unzipped. Open pz_7z030.bsp in a zip extraction tool. I use 7-zip
 - Dig down 2 levels and extract folder pz-7z030
 - Browse to pre-built\linux\images
To get an understand of what is inside that folder and how to use it, refer to

Hello,

Hello,
 
It is not really clear what you are trying to do. Please start a new forum thread and explain exactly what files and versions you used, what steps you took, your hardware (PicoZed 7015 and PicoZed Carrier Card?), the version of Xilinx tools you are using, and your host PC OS.
