No I2S1 activity for rt5640 after moving to l4t32 from 28

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX1

Hello,

After migrating to l4t32 from l4t28 can’t make rt5640 work on TX1.
Codec initialization goes without errors. Mixer is configured the same way as it was on 28, pinmux is configured the same way.
But when I play an audio file using aplay, nothing is happening on I2S1 bus.

Here is trace from playing a wav file, please let me know if any other dumps or info. are required.

cat /sys/kernel/debug/tracing/trace_pipe

Please using jetson-io to configure the pinmux first.

Hi Shane,

Creating custom device tree overlay has helped.
sudo /opt/nvidia/jetson-io/config-by-function.py -o dtbo i2s1

I2S1 is alive again and I can hear the sound.
There is new issue I’m have right now. Seems like playback speed is like 0.5x of what it supposed to be and sound is distorted.

Please let me know if you have any ideas for troubleshooting.
Thank you.

@dima_t
Could you dump the clocks by below command to review.

sudo cat /sys/kernel/debug/clk/clk_summary

@ShaneCCC

Please find the 2 clk_summary logs attached.
v28 is where sound quality doesn’t have any issues.
v32 is the one with issues.

I’ve already noticed that on ver. 28 i2s1_sync = 24000000 and on ver. 32 i2s1_sync = 24576000.

What are these units, is 24000000 = 24 MHz?
Please let me know where it should be configured if it is a culprit.

clock_summary_v32.txt (56.5 KB)

Thank you.

Hi dima_t,

i2s0 is the relevant clock and it seems to be same in both the r28 and r32 dumps. Sync clks are not used in default DT configuration and assuming that you did not modify them either.

Answer below questions to help check this further and attach DT, machine driver patches made and the noisy recording

Which format are you trying to play? Is it 44.1K, 16 bit Stereo data?
Is the codec configured to operate in master or slave mode? What is the source of codec SYSCLK? Ensure that its same on both r32 and r28.
Is LRCK and BCLK reading same on both r28 and r32?

Thanks

Hi @atalambedu,

Please find answers to questions below

Sync clks are not used in default DT configuration and assuming that you did not modify them either. - No.

Which format are you trying to play? Is it 44.1K, 16 bit Stereo data? - Multiple files including 44.1K 16 bit stereo, (other rates have this issue as well) here is the sample file.

Is the codec configured to operate in master or slave mode? - Slave
What is the source of codec SYSCLK? - MCLK, source is the same for both but actual probed frequencies using scope don’t match.
Is LRCK and BCLK reading same on both r28 and r32? - LRCK is 44.1 kHz on both, BCLK is 1.41120 MHz on both.
MCLK is 11.2897 MHz probed on r28 as it supposed to be and it matches clock summary.
MCLK is 2.82241 MHz probed on r32 looks quite low, even though clock summary shows 11289600 Hz for extern1 (please correct me if extern1 != MCLK)

Here is DT and machine driver for r32.

Hi dima_t,

MCLK should be 256*fs i.e 11.2897 MHz in case of 44100 playback and this could be causing the issues with sound on R32

Also, note that tegra_machine_driver_mobile.c is the relevant machine driver used on R32. So, if you had made any changes specific to the codec, please port them to this driver.

Refer codec porting guide and troubleshooting guide for help while porting

Thanks
