HiFive Unleashed Expansion Board Bitstream Missing


On the HiFive Unleashed Expansion Kit Quickstart Guide, under Getting Started step 2, it says:

  1. Update the PolarFire FPGA with the FPGA bitstream labeled HFU540_EXP_Bitstream_r10101.stp from https://www.microsemi.com/hifive-unleashed-expansion-board. Use the FlashPro4 programmer and the programming and debug software for PolarFire available for download at https://www.microsemi.com/document-portal/doc_download/1243247-download-programming-and-debug-polarfirev2-1-for-windows. Launch the installed FlashPro software and create a new project. Click on Configure Device and browse to the FPGA bitstream you downloaded.

However, the link to download the .stp file is deprecated. I’ve been unable to find the bitstream file online.

Does anyone have it?

Type “hifive unleashed” into the microsemi.com search bar, and you should be able to find the stp file, along with some other useful documents, like the quick start guide that explains how to properly power the board.

Unfortunately, it looks like the main microsemi.com page for the HiFive Unleashed has gone missing.

I was able to find the page, with working links, in google cache: https://webcache.googleusercontent.com/search?q=cache:M2sfRG-icvAJ:https://www.microsemi.com/hifive-unleashed-expansion-board+&cd=1&hl=en&ct=clnk&gl=us


Not sure why I didn’t think of that, thank you!
