    Problems with audio driver in Petalinux

    Hi, The documentation from this part is basically ..... useless (and usually slows you with erroneous parts). An example: clock-names = "axi", "i2s"; This line define the clocks for devm_clk_get on the Device Tree, if you check the driver (axi-i2s.c 3.15.x): 204 i2s->clk = devm_clk_get(&pdev->dev, "axi"); 205 if (IS_ERR(i2s->clk)) 206 return PTR_ERR(i2s->clk); 207 208 i2s->clk_ref = devm_clk_get(&pdev->dev, "ref"); 209 if (IS_ERR(i2s->clk_ref)) 210 return PTR_ERR(i2s->clk_ref); So you need to change your DT to something like this: clock-names = "axi", "ref"; This make the driver to claim the clock and finalize the probe function but you're a long way to make it work. I've got something functional with alsa and all controls (I can't use the xilly trick with pulseaudio and the fifo devices), but I'm out of time to sanitize the code. If you can wait some days ... there is hope ,D Gerds, GG.

    Zybo voucher and vivado license

    Hi there, I've four Zybo boards with four vouchers for vivado. The question: Can I use one -and only one- license (full seat, node locked, device-locked for vivado) for generate bitstream for all of the Zybo boards that I have ? Or I need to claim all vouchers for the four zybo ? Thanks, RoTTe
