PicoZed Flash Upgrade

The Flash image for the PicoZed SOMs that ships from the factory has been updated. All SOMs manufactured after 15 June 2015 will have the new image. Advantages of the new upgrade include:

  • Update to PetaLinux 2014.4, which eliminates some Ethernet performance issues present in earlier kernels
  • Uses QSPI for bitstream, FSBL, and U-boot with eMMC to hold the kernel image
  • Includes fix to Linux kernel which occasionally caused the eMMC to hang
  • Scripted to allow the user to bypass the Avnet Factory Test which requires extra loopback devices and connectors
  • Corrects previous 7015 and 7030 failures to load the bitstream and boot past U-boot into Linux
  • The MTD partitions are now consistent across all PicoZed variants, which means for the factory test we can use the same image.ub file for every device.
  • Adds e4fsprogs package to allow ext4 formatting of eMMC
  • eMMC is dual partitioned with a 128 MB FAT partition (to hold the Linux kernel) and a 3.3 GB ext4 partition for user space

Hi Joe,

Hi Joe,
 
I asked our manufacturing team, and they tell me that they have not yet initiated a build with the new Flash image. I have asked them to monitor the serial numbers so that I can replay back here when that happens.

Am I missing something?

Am I missing something? When I click on the link to the Restore/Upgrade QSPI Factory Image (http://picozed.org/support/design/4736/71), I just get a page that says "no results"
