TOPIC: UMA-8 no I2S output in raw mode

UMA-8 no I2S output in raw mode 1 year 3 months ago #42843

bitscientist Offline Fresh Boarder Posts: 3 Thank you received: 1 Karma: 0	Hello, I just received a UMA-8, the marking on the board is Rev 0.5 Nov 6 2017. However, the Readme.txt says the firmware is for board Rev 0.6 or later, did I receive an old board? Also, I'm using firmware micArray_vf_raw_v1.0_up.bin I do not see activity on the LRCLK, BCLK, I2S_OUT_0 signals. The MCLK is active. How do I enable the I2S signals ? Thanks.

With the micArray_vf_spk_v1.2_up.bin firmware I can observe activity on the LRCLK, BCLK, I2S_OUT_0 signals and I can play audio with a I2S DAC board, that confirms the board is ok. But with micArray_vf_raw_v1.0_up.bin raw mode it does not work. Please miniDSP, enable the digital output in raw mode! Thanks.

I read one paper homes.cs.washington.edu/~gshyam/Papers/whitenoise.pdf anranw.me/papers/whitenoise_poster.pdf They used UMA SP to get 7 channel audio and play audio. I current use the V2 but it doesn't work.
