Supported Device Architectures

Table 1. Supported Device Architectures
Architecture Flash Types Example Devices
Versal QSPI, OSPI xcvc1902, xcvp1202
Zynq UltraScale+ MPSoC QSPI xczu9
Note: OSPI flash types are only supported on Versal devices.

Supported flash types are as follows:

QSPI Types
  • qspi-single-x1
  • qspi-single-x2
  • qspi-single-x4
  • qspi-dual-stacked-x1
  • qspi-dual-stacked-x2
  • qspi-dual-stacked-x4
  • qspi-dual-parallel-x8
OSPI Types (Versal Only)
  • ospi-single-x8
  • ospi-dual-stacked-x8

Common Options

Most subcommands share the following options:

Table 2. Common Options
Option Description Required
-u, --url Hardware server hostname (for example, oyster2) Yes
-f, --flash-type Flash configuration (for example, qspi-single-x4) Yes
-t, --target-index Target device index (default: 0) No
-v, --verbose Enable detailed diagnostic output No
Note:
  • list-targets requires only --url (plus --verbose).
  • generate-template accepts only --output; it does not support --url, --flash-type, --target-index, or --verbose.
  • run also supports -i/-o as short forms for --input/--output.

Verbose Mode

Pass -v or --verbose to enable detailed diagnostic output. Verbose mode shows device detection details, firmware deployment progress, and additional diagnostic information useful for troubleshooting connection issues.
