Fohdeesha MASSIVE BUG FIX: boot from RAM, not flash
thought we were booting fresh image from RAM, but the "boot" command with stock env variables was booting the old, probably corrupted fastpath image on FLASH. Thanks to Ulli for discovery

Documentation for flashing Brocade TurboIron firmware to Quanta LB6M. And now for cross-flashing other switches too!

Q. Why does this work without modifying the firmware?

A. When Broadcom introduced the BCM56820 switch ASIC, they released a reference design - a suggested switch design implementing said ASIC. Several companies including Brocade and Quanta took this reference design, built it, added their own branding, and sold it as a product. Therefore the switches are nearly identical, aside from small differences like LED configuration. They both have:

  • MPC8541 PowerPC Management CPU
  • BCM56820 10gbE Switching ASIC
  • BCM5482 Management Port PHY
  • BCM5464 Copper Ports PHY

Because of this, firmware written for one platform will have no issue running on the other - it's the same hardware.

Open to PR's! If you know of any other switch pairs that are the same underlying hardware and would like to cross-flash, let us know! We're mainly seeking firmware candidates for the LB4M - so far we can't find any other switches with the same hardware configuration. We need to find a switch that uses a MPC8541 management CPU + BCM56514 ASIC
