and I was unable to program an ATTiny85 on a breadboard when running at 3.3v (it worked fine at 5V), so I decided to bite the bullet and attempt to update the firmware on the USBASP using one of my Arduino boards as the programmer.
There appears to be a lot of misleading and confusing information on the web about how to do this, so I thought I’d document what worked for me.
One of the Gen8’s key features is the easier process of updating the firmware without using the traditional update CD.
Before VMware or any other OS is installed on your new server I always recommend to update the firmware immediately.
HP is always releasing new updates and they can truly improve the performance and reliability of your server.
Overall I like what HP has done with the firmware update process.
The QPLFO has four ATtiny85 chips: one for each channel. To program the channels, you must apply a gate signal to the Reset and Ping jack for the channel you’re programming. Note: It’s usually fine to use a passive mult to split one gate signal to all the Reset and Ping jacks.
This allows you use HP SUM to update all Moonshot System firmware except for switch firmware files.
Switch firmware updates must be done from either the Moonshot i LO CM firmware CLI or from the switch CLI.
We obtained a bunch of Gen8 Blades for a client down in Florida and I figured I would create a quick “how to” guide on updating the firmware.
Updating firmware is a process that is usually uneventful besides the butterfly effect in your stomach until you see the final reboot get past the initial BIOS screen (most people will relate to this).
I very much like the concept of not having to use the Firmware Update CD for several reasons.
Since HP constantly updates firmware you would normally have to fumble around the HP site and re-download either the updated ISO or the individual update.
