1Steps to compile 2################ 31. Download the latest PCI Utilites source from 4 https://www.kernel.org/pub/software/utils/pciutils/ 5 6 (Or) Source can be clone from the GIT repository, 7 http://git.kernel.org/cgit/utils/pciutils/pciutils.git/ 8 92. Compile the PCI Utilities by the following command, 10 $pci-utils> make 11 123. Compile the MCAP Library by the following make command, 13 $mcap-lib> make PCIUTILS_PATH=<PATH to PCI Utilities Source> 14 154. Compiling the MCAP library generates 'libmcap.a' and 16 example elf 'mcap' built on top of generated library. 17 18Steps to Run 19############ 20-> Running the 'mcap.elf' with '-h' lists all the options 21 that are available to communicate with the underlying 22 MCAP device, 23 $Linux> ./mcap -h 24 Usage: mcap [options] 25 26 Options: 27 -x Specify MCAP Device Id in hex (MANDATORY) 28 -p <file> Program Bitstream (.bin/.bit/.rbt) 29 -C <file> Partial Reconfiguration Clear File(.bin/.bit/.rbt) 30 -r Performs Simple Reset 31 -m Performs Module Reset 32 -f Performs Full Reset 33 -D Read Data Registers 34 -d Dump all the MCAP Registers 35 -v Verbose information of MCAP Device 36 -h/H Help 37 -a <address> [type [data]] Access Device Configuration Space 38 here type[data] - b for byte data [8 bits] 39 here type[data] - h for half word data [16 bits] 40 here type[data] - w for word data [32 bits] 41 42 NOTE: Specifying MCAP Device Id option is mandatory for the application 43 to run. For example, 44 $Linux> ./mcap -x 0x8011 45 Xilinx MCAP Device Found 46 47NOTES 48##### 49. PCI Extended Capability Registers in Linux will only be 50 accessible with privileged user access. So, the example elf should 51 be run with ROOT permissions. 52 53. To access device configuration space, 'type' in the above syntax should 54 be either b/h/w (byte/half-word/word). For example, 55 56 -> Reading a byte 57 ./mcap -x 0x8011 -a 0x354 b 58 59 -> Writing a word 60 ./mcap -x 0x8011 -a 0x354 w 0x3 61
