Sorry to bother you, I have some urgent questions: @nikkov@Darmur
Question 1
i2s in master is enabled by default in neo3,how to enable MCLK output ?Can it be achieved?
I want to connect my 1794DAC(need mclk) by i2s in master
Question 2
When I first time ran Volumio on NEO3, Wireless USB Adapter is enabled and the power light is flashing normally,
You don’t need a network cable, just a wireless USB adapter to connect to the LAN.
When I burned the image on the SD card again and re-ran volumio, the Wireless USB Adapter would not be enabled again(The Wireless USB Adapter works as a hotspot) and the power light would turn off. Changing the SD card and the image version is the same(the Wireless USB Adapter not enabled )
I confirm what I said above. My Wireless USB Adapter isn’t broken.
the kernel package for those images has been created by @nikkov , I don’t know if it’s possible to enable the MCLK output
some WIFi chipsets have problems with scanning the available networks if the hotspot is active.
I’ve personally tested dongles based on RTL8821CU and RTL8811CU chipsets, they work without problems.
Sorry I can’t answer to your question. Datasheet RK3328 is not clear and I can’t find any usable information. I look kernel source code and see that mclk out can be only 12MHz, but we can’t use this frequency not for 44100 or 48000.
