Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Firmware update challenge

I'm attempting to update the firmware on a set of DSP7200SE's.

When I run fupload, it shows an alert "A manual reset is needed" and instructs me to turn the speaker off then on again.

I do so, and then dismiss the alert dialog, but attempting the update again results in the same message.

Any thoughts as to what I might be doing wrong?

Thanks

Please explain what you are using for hardware to do this. I do this all the time and it normally just works without having to turn the speaker off and on.

Bruce,

It's a hodge-podge:

Intel based macBook Pro (i7) running parallels 16 running Win10
Cable = USB-c to USB-a adaptor > keyspan (USB to serial adaptor) > serial to ethernet adaptor > ethernet cable to speaker

fupload appears to see the speaker. That said, hitting the "Identify" button results in a failure to identify

I'd be grateful for any guidance

Thanks

Find yourself a blue Cisco console cable to avoid the serial to ethernet adaptor. I know that the Cisco cable works and they are cheap and everywhere. Secondly, if you love the Meridian sound as much as alot of us do, buy a cheap secondhand Toughbook or Dell 600m laptop that has a real serial port thus eliminating the USB to serial adaptor. Both laptops will already have some form of Widows running on them and will just work. As you don't have to connect them to the internet for any reason, security will not be an issue. Firmware, mconfig, winfup can be loaded via USB stick. These options just work and can save hours of frustration.

Bruce,

Thanks very much for the guidance. I'm going to take both of your suggestions.

Not sure what your baud rate is set to but probably quite high. Try reducing it 2400 and trying again. I had similar problems with D5Ks

It was a good thought, but I'm still stuck. Time to buy a PC as you suggested.

Thanks

I have a vague recollection of having this issue upgrading my ID41 and, from memory, the upgrade software didn’t like the way I had the Ethernet port configured in Parallels.

I think I solved this by giving Windows its own IP address via DHCP from the Parallels configuration options rather than sharing the IP address the Mac is using (you’ll need to shut down the virtual machine before Parallels will let you make this change).

I’m not sure how relevant this is here as I think the upgrade software might be different, but mentioning it in case it helps...

I have always used my MacBook Pro (i7) running Windows10 to update my 7200SE. I have never had any problems with this configuration. I use an USB to serial converter.

Just want to toss in an some kudos to Bruce and Akimo. First Bruce for his sound advice/guidance and Akimo for not trying to "make it work" with a Mac. I'm not anti Apple=I'm fully invested in the ecosystem. I've got an older PC, Core i7, SSD, 16GB that is actually my Roon server that runs Windows 10 and has a proper serial port. I use it to run Mconfig and perform any necessary updates. Recently I had to update my Prime Headphone Amp and had to grab an old Windows 8 laptop to make it work. Not elegant...but it was done in 10 minutes. We are all going to need some gear that is frozen in time to keep our M gear that is edging toward the same...


S.R.

Thanks to all for the suggestions. I'll give them a shot.

Hi,
I had problems trying to do firmware updates when I first stated out on my Meridian journey.
With some trial & error I managed to find the correct settings that enabled me to connect to a device first time every time and give me a super reliable connection.
Hope this can help you. Regards
