ocpizynq

Description

The ocpizynq command-line tool is used to obtain hardware configuration information about an OpenCPI-supported Xilinx Zynq System-on-Chip (SoC) platform and can be used during development and debugging to determine exactly how the SoC is configured (usually by the bootstrap process outside of OpenCPI). The tool operates on OpenCPI HDL platforms that use the Xilinx Zynq-7000 series SoCs, such as the zed, e31x and plutosdr platforms and on HDL platforms that use the Xilinx Zynq Ultrascale+ chip architecture, like the zcu104 platform.

Specify one of the following keywords as an argument:

axi_hp: Display how the platform’s AXI HP interfaces are configured.
devcfg: Display how the platform’s devices are configured. This operation is not currently implemented for Zynq Ultrascale+ platforms.
clocks: Display how the platform’s clocks are configured. This operation is not currently implemented for Zynq Ultrascale+ platforms.
spi: Display how the platform’s SPI interfaces are configured.

When invoked without options and arguments, ocpizynq displays help information.

Usage

$ ocpixml
Usage for ocpixml (executed from /home/user/opencpi/build/autotools/target-rocky9/staging/bin/ocpixml):
Options are:
  Long name  Letter  Datatype  Multiple? Description
  log-level    l       ULong      No    <log-level>.
                                        set log level during execution, overriding OCPI_LOG_LEVEL
  top          t       String     Yes   <top-element>.
                                        specify allowable top-level elements
  attribute    a       String     Yes   <attribute>.
                                        specify attribute to print, one per line
                                        if name starts with ?, it is optional (blank line output)
                                        otherwise its an error if attr is missing
                                        if no attributes are specified top element name is printed
                                        
  silent       s       Bool       No    <silent>.
Long options are of the form:   --<long-name>[=<value>]
Short options are of the form:  -<letter>[<value>] or -<letter>  <value>
Boolean options have no value; their presence indicates 'true'.  Other types require values.

This program performs functions relating to the XML inside artifact files.
Usage is: ocpixml [<options>] <command> <file> [<file2>]
Commands are:
  get   - extract the XML from the file to standard output.
  strip - remove the XML from the file while copying artifact to <file2>.
  add   - add the XML file <file2> to the file, in place. file2 can be '-' for standard input.
  parse - parse top-level attributes from an XML file

Examples

Display the configuration of a Zynq 7000 series platform’s clocks, specifying an external clock rate of 34.368 MHz:

```
Display the configuration for a Zynq platform’s AXI HP interfaces:
```
ocpizynq axi_hp
```
Display the configuration for the Zynq platform’s SPI interfaces:
```
