Audio codec support

0 votes

I'm attempting to port a WM8753 audio driver for ConnectCore Wi-MX51 JumpStart Kit platform for a customer of Digi. We are using official QNX Freescale i.MX51 EVK BSP (http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/FreescaleImx51Pdk). It has support for I2C/I2S/SDMA devices except Wolfson audio codec.

On the i.MX51 EVK another audio codec (SGTL5000) is installed and it works fine with the same BSP. On the Wi-MX51 we have found that TX FIFO of the SSI interface (base 0x70014000) has been filled (SFCSR[TFCNT]), but it doesn't transmit data to the codec.

The linux BSP (kernel 2.6.31) configures only AUD3_BB_* iomux pins. What have we missed?

Hi Andrey,

I am trying to QNX Freescale i.MX51 EVK BSP on the ConnectCore Wi-MX51 JumpStart Kit platform. But the system fails to boot.

Can you please let me know the changes you made to the BSP.

I don't think the Freescale BSP will run on a ConnectCore, you'll need to get a copy of DEL. You can find the download here: http://ftp1.digi.com/support/patches/i.MX51/CC_i.MX51_Updates.htm but you'll need to purchase a key to install it.
