The good news is, polled and interrupt driven mode still work! The bad news is that DMA mode hangs up the kernel on the first read attempt, stalled waiting for the transfer completion notification (hmmm.... I think this was a spot where things were tweaked a bit? :) ) I'll see if I can narrow it down some more if you don't get to it first. > Also, do you have patches adding SPI support for DA850 platform? > I can include these patches on this branch so others who will be > testing don’t have to repeat the work. > I cloned your repository at [1] and published the additions needed to made to test it on the mitydsp-l138 platform (da850 based) at [2] (never mind the UART one at the end). I had to add clock support for the spi devices and define the platform SPI resources/registration routines. I'd appreciate a quick peek at those to make sure that I didn't make any errors. The spi registration may be refactorable (sp?) to support da830, I didn't look to closely at that. If any of it is usable, great. > Thanks, > Sekhar > > [1] > http://arago-project.org/git/projects/?p=linux-davinci.git;a=shortlog;h=refs/heads/davinci-spi-rewrite > [2] http://support.criticallink.com/gitweb/?p=linux-davinci.git;a=shortlog;h=refs/heads/spi-testing -Mike ------------------------------------------------------------------------------ Beautiful is writing same markup.
