Hello All,

This has been discussed multiple times in the group but it is worth raising it again.

On both of the TinySA and TinySA Ultra firmware download pages on Erik's website, there is an excellent explanation on how to use STMCubeProgrammer to update the firmware on either of the TinySA variants. It also mentions the fact that the screen will go white on the original TinySA and blank on the Ultra when in DFU Mode.
For Windows, STMCube is definitely the easiest way to do a firmware update on the the TinySA (and NanoVNA-H & -H4).

After you update the firmware, make sure you do the following:
1. Clear Config
2. Calibrate
3. Run Self Test

If it fails Self Test, make sure you have connected the 2 SMA connectors together with a short SMA-M to SMA-M cable supplied with the unit and repeat the above three steps.
It is also recommended that you fit SMA M-F "connector saver" adaptors to each port to minimise wear in the device connectors.
These are much easier to replace than the device PCB mounted connectors:-).
