Topic: Problems with Fireface 800 firmware update from iMac
I have been trying to connect an RME Fireface 800 to my 2017 iMac running macOS Catalina version 10.15.
I have read reports from others online who say that this can be made to work, but I’m having problems.
Here is what I have tried.
1. I bought the Firewire to thunderbolt connector and thunderbolt 2 to USB3 connector and a firewire 800 cable and connected the Fireface 800 to my Mac.
2. I downloaded and installed the appropriate Fireface 800 driver (3.391) from RME.
3. I attempted to start up the Fireface 800 with the installed driver, but this produced a warning about incompatibility of the firmware with the driver, and said I needed to update the firmware.
4. I downloaded the flash update tool revision 1.71 and 2.77 (compatible up to 10.14 macOS Mojave), but received the warning that this update tool needed to be updated. I gather that was because it is a 32 bit app and Mac OS Catalina (10.15) does not run 32 bit apps. I could not find a version of the firmware update tool that was compatible with MacOS Catalina, even though the Fireface 800 driver is.
5. I found that the last version fo Mac OS to run 32 bit apps was MacOS Mojave (10.14), so I decided to try to run that on a separate drive so that I had the option to run that OS on my computer temporarily in order to run the 32 bit flash update tool and update the firmware on the Fireface 800 before then using it under MacOS Catalina. The flash update tool is supposed to be compatible with this version of MacOS Mojave 10.14.
6. I installed MacOS Mojave 10.14 on a separate external drive and rebooted from that.
7. I downloaded and installed the Fireface 800 driver (3.391) and flash update tool (revision 1.71 and 2.77) under MacOS Mojave (10.14). Both installed fine, so I connected up the Fireface 800 and tried to update the firmware. The flash update tool actually ran this time and went through all of its steps. But, at the end of the programming step, which seemed to have finished, it reported the warning: Revision 2.04 /Status Failed with error D0000000. I gather from this that my Fireface 800 is currently running revision 2.04 of the firmware, and that it has not been updated. I was not sure what to try next.
8. I tried to download, install and run the older version of the flash update tool (I could only find two on the RME website), but it also ran and then reported the same information and failure.
I found a vague suggestion online to try from an older computer or older version of MacOS, but it didn't say which one would work. There are many older versions of MacOS, and installing a new OS version each time to try to solve this by trial and error is just too time consuming. Is there a specific version of MacOS for which a Fireface 800 firmware update is known to actually work?
Can anyone help me out here with any other suggestions on how to update the firmware on this Fireface 800 and how to get it working on a 2017 Intel-based iMac running Catalina? I’d really like to use this FF800, and I’ve read numerous reports on line that it should work with the configuration I have.
Thanks!
