Headphone Amp Any help available for K7 update procedure ?

[Akhnaten]

Hello,

I'm new owner of a Fosi Audio K7, and I don't find any information and/or process to ensure firmware and driver update,
and be sure to always keep it up to date !

The product page says the XMOS firmware can be updated via Type-C, but I cannot find any public K7 firmware package or version-check procedure.

Can someone confirm if it's possible to update the firmware on this device, and if so, how ?

Does the driver automatically notify me when a new version is available, or do I have to check the website regularly ?

Thanks for your help !

After looking into it and contacting Fosi Audio support directly, I can confirm that the K7 firmware is updatable, and that the latest version currently available is v2.32.

Fosi sent me a Google Drive link to download it.

The update itself is very straightforward: it comes with a small flash tool, and the whole process only takes a few seconds.

What is frustrating is that Fosi does not make this firmware package + flash tool publicly available.

In the “Manuals & Downloads” section for the K7, they only provide the driver.

I suggested that they should either upload the firmware package there as well, or simply bundle it with the driver package,
but as far as I can tell, they still have not done it.

It would be much better if K7 owners could check for firmware updates and install them on their own, just like they already can with the driver,
instead of having to email support every single time just to ask whether a newer firmware version exists and then wait for them to send it manually.

Especially since it would be so easy for Fosi to just add it to the “Manuals & Downloads” section for everyone.

If you own a K7, feel free to mention this to Fosi support as well. The more people ask, the more likely they are to finally make the firmware
publicly available.

Hi,


Thank you for sharing your experience and the details about the v2.32 firmware. I completely agree with you — it would be much better if Fosi made the firmware + flash tool publicly available in the Downloads section, just like the driver.


I already contacted Fosi support (I replied to their welcome email mentioning the Bronze Tier) asking for the v2.32 firmware. While I wait for their reply, could you tell me roughly how the update process works? For example:


• Do you need to put the K7 in a special mode (DFU)?


• Is there any risk if the update fails?


• How long does it really take?


Any tips would be really appreciated. Thanks again for raising this point!


Best regards,
