Re: [Gumstix-users] SPI Issue :- (spi1.0: DMA RX last word empty)

[jumpnowdev <sc...@ju...>]

You might try this patch on your 2.6.34 kernel. It's in later kernels.

http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=commitdiff;h=8b66c13474e1683d53255f3b2948231b61cdaefd

Possibly it will avoid that last RX byte problem with SPI DMA by using SPI
in PIO mode instead.
The commit message from the Nokia guys indicates that it should not hurt
performance and might actually help.

Just an idea. I didn't test.
