You can attempt an upgrade via OS X. However it didn’t work on my end - The OS X upgrade software isn’t well written, according to @terry.

From the spec, it was said tone board can support pcm 32bit 768khz, why the new firmware only supports 32bit 384khz, what I missed here?

The original spec was in error, we have since corrected it on https://www.khadas.com/tone-specs as well.

Hi youjun,

Why khadas cannot support 768khz? Is that a limitation from hardware, oscillator?

Hi @tsangyoujun

Is there by chance planned any upgrade to newer version of USB drivers for example 4.xx series? :wink: This would be fantastic since there are active firmware made :wink:

Is there any reason for using the 4.1 Eval version to update the board? Is it not enough the TUSBAudioDfu.exe file installed with the v2.24 drivers?
