Firmware upgrade

[moonchild]

Hi,

I have an rp8420 with firmware version 3.0 and I am planning to upgrade to the latest firmware revision which is 4.0
is it ok to go straight to the latest firmware revision? any known problems? or gotchas?

thank you in advance

This is clearly written inthe doc "Read before installing"

If you are upgrading a system or cell to version 4.0 from 3.1 or lower it is VERY IMPORTANT that the release notes be followed. DO NOT perform a reset of any entity or cell until ALL the required firmware, both OSP and FW files, have been updated

Release notes says at no. 6:

If updating from a version prior to 3.3, perform the following step to update FPGA files. If the system is already at version 3.3 no FPGA updates are necessary, proceed to step 7. Launch the Onboard Scan Programming (OSP) Utility to update the Programmable Hardware (FPGA) components that changed in version 3.3:


System Backplane GPM version(s) to 1.003
Core IO version(s) to 2.011

... using the command: MP:CM> osp
