Re: Can't update firmware

dfusedemo.exe is definitely not working for me. I just tried the 'Upload' function in the tinySA app, and it's certainly not intuitive. For example, it says to 'press the Open Folder button above this memo...', but there is no such button. When I put the TinySA in DFU mode, the DFU Device line fills in with 'Port_#0007.Hub...', so it's apparently seeing the device, but the Upload Firmware line shows four cryptic choices, like '1-of-11 H LSI'. If I click the folder icon there, and then select the DFU file that I saved on my desktop (tinySA_v1.3-317-g9d82970.dfu), it adds .url to the filename. If I then click 'Open', I get an error message saying the file is too small to be valid. Does any of this make sense to you?

I also have a SARK-110, and have never had any trouble upgrading it. I just copy the new .dfu file to it, hold a button down at power-up, and it's done. Why does this have to be so difficult? (I'm sure there's a good reason!)

I appreciate your help, and Larry's too. (I ran zadig, but it didn't help.)

Hey Terry, I just upgraded two Tiny SA's (one older and one the newer version) to FW 1.3.317 with no problems. I did it this time with the TinySA-app using the applications built in upgrade function. Smoother that the DFUdemo. However, for previous versions I have used DFUdemo, also with no issues. If you aren't using TinySA-App (available at (), but are using the DFUdemo program, be sure you are using the "Upgrade" section, NOT the "Upload" section and have the correct .dfu file selected (can be found on the site above).?

I also believe that I did run into a recognition issue, a while back,with the DFUdemo program seeing the device with either the TinySA or the NanoVNA. I had to either connect the device first, switch to DFU mode, then fire up the DFUdemo program for it to see it. But if you can connect the TinySA to the PC (assuming you are using a PC), and it shows up in device manager under the COM ports, when you switch to DFU mode, the COM port drops and it shows up in?USB Serial Devices.

I'm sure some of the other guys on here will also respond with good suggestions...Good Luck....Ted (KD7AQO)

Subject: [tinysa] Can't update firmware

I've downloaded dfusedemo, version 3.0.6. With it running, I connect the TinySA and put it in DFU mode, but the application doesn't find it. If it's any help, when I enter DFU mode I get the 'USB disconnect' sound.

I've viewed a couple of YouTube videos, and can't figure out what I could be doing wrong. Also, if I click CHOOSE and select the new .DFU file, the application reports that the file doesn't have the correct format. Seems I have two different issues.
