QMX Not Appearing As USB on Mac OS
Unbelievable - I've been doing firmware upgrades on all my QMX, QMX+, etc. rigs on this Mac Mini since the dawn of time - no problems. Well, tonight I downloaded the new v2.00 firmware and was going to update one of my QMX+ rigs and give it a whirl. No problem downloading the file. he problem is that now my Mac Finder refuses to see the QMX device. PuTTY has no problem connecting to it; MacLoggedDX has no problem connecting to it. But unless Mr. Finder see it, there will be no way to move the new f/w over to the radio. I've even re-booted the computer - no joy. I have not changed anything on this computer nor have I done any system updates. Any suggestions?

Did you try cycling power on the QMX+? On Fri, May 2, 2025, 9:38?PM Jim Bennett / K7TXA via <w6jhb=[email protected]> wrote:

I also have a Raspberry Pi that I'm trying this on. Same issue - QMX shuts down waiting for the f/w but I have no way to see the QMX to move the downloaded file into it. I have two QMX+ rigs - both are doing the same thing on Mac OS and RPI. I must be doing something wrong, but for the life of me I can't figure it out. Arrghhhh....

On the QMX menu, tell it to do a FW update. That will (immediately, I believe!) put it into the mode where you can drop the file for updates.?
Pretty sure a power cycle isn't required, because if you did it would come back up as the original QMX!
Good Luck!

Yes. When I telll QMX to do a firmware update, it does its normal power off sequence and waits for the f/w to be moved into it. It will sit like that till either the cows come home or you unplug power manually, which I've done multiple times.

Paul, that¡¯s what I¡¯ve been doing, but there is no QMX device showing up to drop that file onto.?

Have you checked using a different flash drive, that your Mac is showing external drives in finder? I believe there is a setting under Finder preferences to hide external drives.
Does the QMX show up under disc utility? I can¡¯t immediately see how it could affect it, but also check with a different USB cable and port on the Mac. ?

What I found was that selecting Firmware update and jumping through the hoops shuts the radio down.? Then when you press the Vol button it turns on in update mode, as a flash drive.? This is using a Windows laptop but I'd expect that the QMX doesn't know what it is connected to, especially when it's turned off.

Jim,
What firmware was on the QMX? I can't imagine how just downloading (and not installing) a new f/w could prevent the update from happening. Unless the previous f/w had a flaw, which seems unlikely. Are you sure it is not a bad USB cable? That would be the simplest explanation. Or maybe I'm misunderstanding something.?

Hi all The firmware update is in the bootloader and is never updated. It's only the application firmware which is updated (by the bootloader). 73 Hans G0UPL On Sat, May 3, 2025, 11:04 Daniel Walter via <nm3a=[email protected]> wrote:

Energy the menu
Select firmware update
Press tune to confirm
(QMX turns off)
Click volume encoder to turn it on
Drive appears like magic.
Works for me.

You are right. What used to happen when selecting and confirming ¡®update firmware¡¯ was that a new drive (QMX) would automatically appear in the finder. This update appears to require a power down of the QMX. First time this has happened, not a big issue but an ¡°Oh no!!¡± ¡ moment. MacOS Monterey 12.7. May I add, Well done Hans on all the hard work and no doubt sleepless nights, thank you. . 73 de Rob G?HFN? |
Folks - thanks for the help / suggestions. The problem has been fixed. All my rigs were at the 0.027 level. Prior to that level, I believe there was no need to press the Tune button to make the drive appear. At least that¡¯s my recollection, and I¡¯ve done many prior updates. Seems that perhaps starting at the 0.027 firmware level the Tune button press is required. I did that a few minutes ago and now the QMX+ shows up as a USB drive.?
My printed manual (0.26) does not mention that step. If it isn¡¯t documented in the 0.27 or the new ¡°SSB¡± version, it might be worth adding it. Sure would have save me some big time head scratching yesterday! :-) ?
Thanks again and I¡¯m off to test the new update. 72

Hi Jim It's always required pushing the Tune button to confirm you want to do the firnware update. Not a new feature. And if actually prints on the screen that you should press the Tune button to confirm. Furthermore, it is described in the operating manual (page 76 in the latest manual). Nothing has changed in this procedure. If anything needs to be done to make it more clear please let me know, but right now I think you just missed it ;-)? ? No shame in that, kind of thing I do all the time. Just saying, I think it's there in the manual and on the screen, but if there is any bug please let me know.? 73 Hans G0UPL On Sat, May 3, 2025, 18:15 Jim Bennett / K7TXA via <w6jhb=[email protected]> wrote:

Arrghhhhh¡ Hans, sorry - I mis-typed. It was the Volume button that needed to be pushed. You are correct about the Tune button, and I had done that. After pressing the Tune button, the QMX+ powered off as it was supposed to, but at that point it did not appear as a USB drive. Pressing the Volume button is what magically made the USB thing work. I did it this morning on my Mac mini and also on a Raspberry Pi 400, each with different QMX+ rigs and different USB cables. Identical process - no USB seen until pressing the Volume control. Maybe the phase of the moon? :-)

¿ªÔÆÌåÓýHi Jim, That does not work for me (Win7). Once QMX enters update mode,
nothing works, I need to to unplug the 12V to regain control! -- Jean-Jacques - F5IJO FISTS#17008 LICW#5902 Le 03/05/2025 ¨¤ 19:08, Jim Bennett /

That is what I was having to do - unplug to regain control. If I understand the process correctly, when QMX is unresponsive like that it means it is waiting for the firmware to be dropped into it's "bucket". It will sit there like that (unresponsive) until it gets the firmware or as you and I had to do, unplug the 12V. Unfortunately, unplugging does NOT do the upgrade - ot simply gives you control of your rig at the firmware level you were at before starting.
?
In my case I had no USB device to drop the firmware into until I pushed the Volume control. Once I did that, the QMX appeared, I was able to drop the new firmware onto it, and everything worked as it should. This was what I had to do on Mac OS and on a Raspberry Pi 500. I have no idea what Win 7 is looking for - sorry.
?
And as I mentioned in an earlier post, as far as I can recall, I did not have to do that Volume control push until my QMX rigs were on 1.00.027. Anyway, both of my QMX+ rigs are now at the new "SSB" firmware.

I don't think this issue has anything to do with the specific firmware version; it happens seemingly randomly on some QMX devices.
?
I have 2 QMX and 2 QMX+.? Sometimes the auto-restart into firmware update mode doesn't happen on one of them.? It is as-if the QMX fails to power-up as it resets into firmware update mode.? A press of the power-on button starts it up in firmware update mode, and all proceeds normally.
?
Another similar issue happens sometimes at the end of the firmware update - on one or more of my QMX* devices, the QMX will fail to auto-restart with the new firmware after it is loaded.? I have to remove power, then plug it in and turn it on, and it boots up fine with the new firmware.
?
I have not kept track to see if this happens on the same QMX* device each time or if it is more random - but it is so easy to workaround that I haven't worried about it.
