Hi David, >These are two board specific memory regions. > >Assuming a 'signal processing controller' means that there is >a DSP or processor on the board, then these two regions probably >correspond to regions of the DSP/CPU memory map on the >board. > > There is FPGA Xilinx on this card. Now i can read/write data to/from this card. There are ZBT memeory and flash. I have access to all register on this card. Now i need to use DMA channel. >Do you have information on the memory map of these two regions? > > The first region is PLX register, second and third one are FPGA register and FPGA memory. Now to access to all os these register i use firsta of all ioremap_nocache and after readb/writeb. >I can send you a driver that finds the PLX-9054 device and allows >you to memory map these regions. I can also show how to mmap >the two other regions - this allows programmed I/O from >user space - good for checking things out. > > If it is not difficult for You, it was nice. thanks, Kirill -- Kernelnewbies: Help each other learn about the Linux kernel.
