    Hi I'm experiencing a problem with using SD cards in Linux on Logic's OMAP-L138 eXperimenter Kit. When I compile the kernel to support SD cards (http://tiexpressdsp.com/index.php/GSG:_Building_Software_Components_for_OMAP-L138#Driver_configuration_in_the_Linux_kernel) system detects them, but...

    We are building a product from the OMAP-L138 with an audio codec. For the protos we want to use the TLV320AIC3254 instead of the AIC3106 on the L138 development board. However time is critical and thus we are looking for the ALSA Codec for the TLV320AIC3254 . In the beginning we only need the same capability...

    Hi Rob, Thanks for the feedback. <blockquote> As for the Linux Utils EDMA package, it is intended for non-DSP devices only. DSP-based devices use the EDMA LLD (Low Level Driver) with DSP/BIOS to manage their EDMA resources. </blockquote> What is then the recommended Linux user-space interface...

    Rob, Robert Tivy I don't know of any user-space interface to QDMA (or any EDMA) channels. QDMA usage would be encapsulated in a Linux device driver, and its usage by the device driver is generally hidden from the user. That is my understanding as well. But if I end up needing such a user...
