DM3730 Linux SPI Driver

Other Parts Discussed in Thread: DM3730

Customer needs to use the DM3730 SPI bus and is having some difficulty.  They tried a number of Linux Kernel configurations with a variety of SPI drivers enabled.  In web searches we’ve seen a few comments about spidev and they can create a Kernel that has this loaded, but even with it loaded, there is not a /dev/spi_xxx to be found.  I’ve done a lot of searching and I haven’t found a clear solution to this problem.  Can you shed some light on this?

 

I have also attempted to control the SPI directly via memory mapping, but once completed I can neither read nor write to a memory mapped register without causing a bus error.

 

Please advise.

 

Thanks,

Mark
