A Tutorial on the Device Tree (Zynq) -- Part V Setting up a device tree entry on Altera’s SoC FPGAs Xillybus' IP core offers a simple and intuitive solution for host / FPGA interface over PCIe and AXI buses. 1 was an initial release and was 32-bit user space, but 64-bit kernel space. the simplest way to enable or disable the internal clock delays is through the device tree. Hardware . The easiest way to disable the DMA mode is to overwrite the dma-names property (see also Device Tree Customization): Re: Ultra 10 and Sparcengine AXi compatibility 807559 Aug 15, 2001 9:12 PM ( in response to 807559 ) Hi Turk, Unless the the components in both systems are hot swapable, you will need to perform a reconfiguration boot, or do a 'devfsadm' to rebuild the device tree
