NanoVna H-4 stucks


 

My new analyzer stucks when I turn it on. Touch Screen do not work.
It generates error: si5351-init failed.
What is wrong?
Version 0.5.0

You probably got a device from the first production, the fault of which was that the cover was pressed against the touch screen and due to constant pressure it could not log in either.
What to do: Unscrew the cover and place a plastic washer (0.5mm) on the screw towers and screw the cover back on.
Hopefully I guessed well.

Since the firmware was made a year ago, please update the firmware to the latest 1.0.45 so that you can use it with the latest software. NanoVNA-App v1.0.205. Read my website for details.

Hi Ossi,

DfuSe: Upload vs Upgrade

Upload refers to backing-up (ie: reading) the device's firmware TO the PC and saving it to a local file.
Upgrade refers to flashing new firmware INTO the device from a DFU file on the PC.

The si5351 is damaged. This NanoVNA-H4 may be a clone. I suggest you contact the dealer to replace it.

Folks,
In order to make the DeFuse GUI better understandable, I created a version with better command labels.
You can find it in thew forum's FILES section here:

Follow the instructions in the zipped file.
