Firmware Won't Update
|
Hi All, had my VNA-H for a short while and decided it was time to update it, mine is board V3.3, firmware 0.2.3.2, using DFUse, I put my unit into DFU mode and uploaded the latest upgrade. As i have the DFU option in my config, i assume i did not need to short the 2 pins together, that said, the software showed success at every stage, but my device is still stuck on its original firmware, help please.

Hi Dennis,
I think the solution is written here: /g/nanovna-users/topic/51160730 if not, use and read the wiki description it seems to me that for the first time the lack of a driver between the computer and nano is the source of the problem. 73, Gyula HA3HZ |

This may be a stupid remark but:
The DFU "Upload" is for making a backup of your nanoVNA flash memory to you PC Use the "Choose" and "Upgrade" keys to update the firmware -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK |

Hi Dennis,
To date, I've only upgraded the firmware once with the ST-Link dongle because it was in my account for a different reason. I had no problem with that, otherwise someone would recommend it if DfuSE fails the upgrade. You can also find a detailed description in the wiki or on my site (ha3hz.hu). Hope I was able to help with upgrades. 73, Gyula HA3HZ |

DfuSe uses weird terminology. "Upload" means to take a snapshot of the

device and save it on your PC (it uploads from the VNA to your computer?) You have to use the box on the right to download to the VNA - not the "Upload Action". Pick the file using "Choose", then click on the button to the right to download that, or install that, into the VNA. (Some versions of the DfuSe utility changed the "Download" text to read "Upgrade", making the right-hand box easier to understand.) If an upgrade/download with the "Verify after download" is checked (and doesn't get any errors!) doesn't result in a firmware update, then that's pretty strange. Also - if you did a Upload and chose the firmware file for 1.1.0, you've just overwritten that file with the 1.0.45 code. That means that a correctly done Update/Download just reinstalls the existing code. Pull a new copy from the internet. 73, -Rick On Fri, Dec 31, 2021 at 1:01 AM Jim Barber <jimpbarber@...> wrote:

The Dfuse issue you describe has been discussed many times

...and that is why it says in the forum's Wiki there is an alternate exe file I created that renames those buttons. Unfortunately, many forum members don't read the Wiki. (Sigh) .?

I'm using your patched DfuSe tool. Makes it a lot easier to understand what you're doing. It is unfortunate how many people clearly didn't bother to look at any of the resources here. -Rick On Fri, Dec 31, 2021 at 10:15 AM Larry Rothman <nlroth@...> wrote:

"Clearly", and actually people do look at the resources.
However, the issue is not that the firmware was backed up because I actually followed the instructions. I have 3 of these and have never had issues using the DFUse tool before. The other two flashed fine. One before and one after. I am experiencing something different and was just looking for some insight, not beratement. I will try with a different unit. I have a few. I believe this one must be a bad clone or something as it is new. Maybe I will try a different flash tool. I have flashed everything from Automotive computers up to high-end Core Internet routers and just find this a bit frustrating at the moment. |

Jim,
I was actually speaking in general terms, and yes, there are quite a number of folk that do use the Wiki. There is a simple way to verify if that 1.1.0 file you have is ok and that is to open it in Wordpad or a hex editor that can display ASCII strings. Look close to the end of the file and you will see the copyright strings and the version number. The Dfuse utility has confusing names for its buttons and I changed their meanings to be more standardized. The only time that anyone on the forum has described what you're saying, is when they backed up the FW from the device to the file they were trying to flash, overwriting it. Download yourself a new copy of 1.1.0, install my modified dfuse exe file and flash. Have a safe and Happy New Year |
