Hi,
I have:
bfin-spi bfin-spi.0: No DMA channel specified
error. What does it mean? How can I solve it?
In the configuration is specified:
.enable_dma = 0
Regards,
Nikolay

... it is
.enable_dma = 1 for SPI_BFIN, but why is this error? How to specify the channel?

What kernel and toolchain release do you use?
What device do you use with the SPI driver?
Have you tried the PIO mode in SPI driver? Does it work?

The kernel is:
Linux version 2.6.28.10-ADI-2010R1-pre-svn6597 (root@dlnx764) (gcc version 4.1.2 (ADI svn)) #215 Mon Jun 8 17:18:12 IST 2009
and the toolchain is version 4.1.2 (ADI svn)
I'm using MMC device.
I haven't tried PIO mode.
It worked fine with the same kernel and toolchain before, but since one of the builds it stopped. I'm trying to figure out what's happaned...

you need to update your board resources. look at how the spi resources are declared in any of the ADI boards.
