I have created a RAM disk on Zynq RTEMS and I'd like to set up (for the time
being) a 'baremetal ' type DMA transferTo the ramdisk .
I have set up the RAM Disk as follows, and have no problem reading or writing
to it. How do I find the physical address in memory where the
RAM Disk has been created? I think I may be better off allocating a static
memory region for this; my RAMDISK size is 384Mbytes
rtems_status_code create_ramdisk(
const char *device,
uint32_t media_block_size,
rtems_blkdev_bnum media_block_count
)
{
rtems_status_code sc;
ramdisk *rd;
rd = ramdisk_allocate(NULL, media_block_size, media_block_count, false);
if (rd != NULL) {
sc = rtems_blkdev_create(
device,
media_block_size,
media_block_count,
ramdisk_ioctl,
rd
);
} else {
sc = RTEMS_UNSATISFIED;
}
