Hi Kim,
Has anyone had any bad experiences with this part, or is there some 'feature' of the part I should be aware of?
it has a different DMA engine than the rest of the mpc8xxx parts. Ilya Yanok added support for it - see Linux commit ba2eea2, drivers/dma/mpc512x_dma.c.
Thanks.
I'd noted that it did not have the external DMA pins that the MPC8349EA has. However, I believe that I can live with that. We had used those pins for flow control with an FPGA configuration controller. However, I can do that with an interrupt if need be.
Ira - could you please take a look at the DMA controller and see if you think it'll work for us.
Cheers, Dave
