Steps to compile
|
|
################
|
|
1. Download the latest PCI Utilites source from
|
|
https://www.kernel.org/pub/software/utils/pciutils/
|
|
|
|
(Or) Source can be clone from the GIT repository,
|
|
http://git.kernel.org/cgit/utils/pciutils/pciutils.git/
|
|
|
|
2. Compile the PCI Utilities by the following command,
|
|
$pci-utils> make
|
|
|
|
3. Compile the MCAP Library by the following make command,
|
|
$mcap-lib> make PCIUTILS_PATH=<PATH to PCI Utilities Source>
|
|
|
|
4. Compiling the MCAP library generates 'libmcap.a' and
|
|
example elf 'mcap' built on top of generated library.
|
|
|
|
Steps to Run
|
|
############
|
|
-> Running the 'mcap.elf' with '-h' lists all the options
|
|
that are available to communicate with the underlying
|
|
MCAP device,
|
|
$Linux> ./mcap -h
|
|
Usage: mcap [options]
|
|
|
|
Options:
|
|
-x Specify MCAP Device Id in hex (MANDATORY)
|
|
-p <file> Program Bitstream (.bin/.bit/.rbt)
|
|
-C <file> Partial Reconfiguration Clear File(.bin/.bit/.rbt)
|
|
-r Performs Simple Reset
|
|
-m Performs Module Reset
|
|
-f Performs Full Reset
|
|
-D Read Data Registers
|
|
-d Dump all the MCAP Registers
|
|
-v Verbose information of MCAP Device
|
|
-h/H Help
|
|
-a <address> [type [data]] Access Device Configuration Space
|
|
here type[data] - b for byte data [8 bits]
|
|
here type[data] - h for half word data [16 bits]
|
|
here type[data] - w for word data [32 bits]
|
|
|
|
NOTE: Specifying MCAP Device Id option is mandatory for the application
|
|
to run. For example,
|
|
$Linux> ./mcap -x 0x8011
|
|
Xilinx MCAP Device Found
|
|
|
|
NOTES
|
|
#####
|
|
. PCI Extended Capability Registers in Linux will only be
|
|
accessible with privileged user access. So, the example elf should
|
|
be run with ROOT permissions.
|
|
|
|
. To access device configuration space, 'type' in the above syntax should
|
|
be either b/h/w (byte/half-word/word). For example,
|
|
|
|
-> Reading a byte
|
|
./mcap -x 0x8011 -a 0x354 b
|
|
|
|
-> Writing a word
|
|
./mcap -x 0x8011 -a 0x354 w 0x3
