imx53 smd sound issue

[vicliu]

Hi, my board is based on the imx53 QSB and uses the SGTL5000 sound chip connected up in the same way.  And I use imx53 smd kernel for Andorid.

When the kernel loads I get this error:-

sgtl5000_hw_read: read reg error : Reg 0x00
Device with ID register 0 is not a SGTL5000
No device for DAI imx-ssi-1-0
No device for DAI imx-ssi-1-1
No device for DAI imx-ssi-2-0
No device for DAI imx-ssi-2-1

No soundcards found.

But while I use imx53 loco for Ubuntu,  it worked. 

Anybody can help me??  By the way, on the same way I2C bus EEprom and RTC both worked.

Hello,vic,

     I checked schematic of MX53_QSB and MX53_SMD, they used the same I2C(I2C2) for SGTL5000, So I2C_BOARD_INFO structure in BSP file should also be same. But the 2 BSP file were designed for different boards, Only according to log, it is hard to judge where the issue from. the following is my adivce for your design:

(1)porting BSP to your board.

Since your design is based on mx53qsb, You had better do porting based on mx53_loco BSP. So please adjust code based on mx53_loco.c.

(2)using android file system.

for i.mx53QSB, Freescale only released linux BSP, but you can compile i.mx53 smd android file system , and run it on your board .

(3)Porting android file system to your board.

You can open android2.3.7(R10.4) source code, and create a new devicee by referring to mx53 smd , such as mx53_xxx, then using samilar method with mx53 smd to compile your own board

It looks like you have added a new EVK board into R10.4
