Question about WM8962 without PMPF0100 PMIC.

edwinrose · ‎08-15-2013

Hi All,

Now I'm developing the freescale i.MX6 platform.

For cost down purpose, I use discrete power solution without PMPF0100 PMIC.

Now I meet a issue about audio WM8962. It seems can't detect WM8962 as the following console.

I'm trying to disable the I2C signal to PMIC on SABRE Board, the same result with can't detect WM8962.

Both power and I2C are normal.

Please help me, thank you very much!

Hi.

DCVDD is at U7 WM8962 pin G2.

The main issue I was having was that there were no power on that pin because the PMIC was not solder correctly. The Linux boot up software was trying to detect the Audio chip and it did not found it. After reflowing the PMIC and all connections were made correctly then the Audio worked fine.

Thanks, Manuel.

You can refer "Porting Audio Codecs to a Custom Board" chapter
of Porting Guide I attached.

manuel_ugarte · ‎10-17-2013

Hello.

The link is broken. Can you please update the link?

Also, I am seeing the same issue reported by Edwin on the MX6Q-SDP and MX6Q-SDP boards provided by FSL.

Manuel.

edwinrose · ‎10-24-2013

Hi Manuel,

I had solved this issue.

Hint you may try check the following items,

1. Check DCVDD power or mask DCVDD in code.

2. Audio detect function.

Edwin

wangtsungli · ‎08-16-2018

Hi edwinrose‌

I'm working on i.MX6 Quad sabreSD platform which without PMIC design on the board too.

Could you help me on the issue when booting system will auto sleep and can not resume.

Is there anything PM kernel driver I need to modify?

Or I need to disabled any kernel driver?

Could you give me a hint?

Thanks in Advanced!

changyuheng · ‎04-24-2014

Hi Edwin,

I'm not familiar with this field. Could you please explain more briefly about the second hint "audio detection function"?

Henry

changyuheng · ‎05-08-2014

I solved the problem. Still not found the root cause, I just gave it a workaround by bypassing checking those power supplies.

IMHO, the size of the power supply array could be refactored to:

-#define WM8962_NUM_SUPPLIES 8
-static const char *wm8962_supply_names[WM8962_NUM_SUPPLIES] = {
+static const char *wm8962_supply_names[] = {
+#define WM8962_NUM_SUPPLIES sizeof(wm8962_supply_names)/sizeof(char *)

in the file sound/soc/codecs/wm8962.c.

manuel_ugarte · ‎10-28-2013

Hi, Edwin.

Thanks for the information. DCVDD on our board was not solder correctly.

Thanks, Manuel.
