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.

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.
