TAS2572: How to add the IV-sense protection algorithm for TAS2572 on Qualcomm platform?

Hi Shenghao,

I don't understand clearly. Can you please call me (15951714197) or discuss with Wechat (same number)?

Hi Shenghao

Does the driver need any changing to support the IV-sense protection algorithm beside configuration the registers?

Hi Shenghao,

These two registers Page0 0xD and Page0 0xE juest control whether to send IV-sense data. Driver need to calculate through these sense data and control the output. 

The RCA drive is now selected. Does it contain the algorithm?

The RCA driver is runing on ARM. But the smart amp's I2S is connection to the ADSP.

Please help assign to the algorithm owner

The email was already sent yesterday. Please expedite sending the speaker protection algorithm implementation, including both the AP (ARM core) and ADSP core versions. Additionally, regarding the link you previously shared: "The driver link: uda20/tas25xx_driver - Unnamed repository; edit this file 'description' to name the repository." — we downloaded UDA_0.0.23_10_K6.12-QCOM, which is just a codec driver upgrade version. We need to replace the old driver with this, correct?

hi ,it's urgent to confirm the new drv we downloaded:UDA_0.0.23_10_K6.12-QCOM,this drv is fully adapter our chip 2572??if yes,we can portting immediately.

One email according the tas2752 drover coupled with firmware causing kernel panic had been send to you. Please help to confirm.

Shenghao Ding  Terry Hu This issue is quite urgent. Please make sure to expedite the resolution.

Hi Shenghao Ding 

We have not receive the response for below email 

Kernel panic occurred after porting the tas2572 driver.  The project has only one speaker connected at any time. But it seems the firm ware tismartpa_driver_tuning.bin contains 2 channels. It cause the panic during parsing firmware.

1. Please review the attached patch and help to confirm if it is appropriate.
2. Please regenerate a firmware contains only 1 channel.
3. Please provide the tool and guide to generate firmware.

Driver branch: kernel_v6.12-qualcomm

which mail?we have not received.thanks.

Hi Wanqin,

Shenghao will reply to you soon. Our another SW apps engineer, will also be involved to look into this issue and provide the fix for the driver issue. Thanks.   

We have not found where to download the patch.zip.

 Shenghao Ding 

As we can't find the attach port in this case, the patch is attached in email ad below. The patch focus on some potential risk. After update the firmware Baojun send yesterday, the kernel panic does not occurred again even without the patch. 

Hi Shenghao,

This task hasn't been finished completely. Now the AP side driver is ready. We still need to porting the ADSP side algorithm. We will close it as the task is finished.

Hi Shenghao & Baojun

We checked the registers during playback is ongoing. The IV-Data is disabled. What should to do to enable the IV-data?

Shenghao Ding Could you please update the firmware cfg/bin to enable IV-sense output by default? Or let us know how to enable it through the new driver — should it be configured in the firmware binary, or does the driver need to write these registers separately during playback start?

Our Jim will feedback you.

Hi Jim

The configure and bin you provided is for RCA driver. We now are porting the UDA driver.

We set the 0D and 0E to 0x42 and 0x40 before playback. And we fond the two register is reset to 0x02 and 0x00 after the playback finished.
