Configure a Hardware Platform for Linux - 2022.1 English

You can create your own hardware platform with Vivado® tools. Regardless of how the hardware platform is created and configured, there are a small number of hardware IP and software platform configuration settings required to make the hardware platform Linux ready. These are described below:

Zynq UltraScale+ MPSoC and Versal ACAP

The following is a list of hardware requirements for a Zynq® UltraScale+™ MPSoC and a Versal® ACAP hardware project to boot Linux:

• External memory of at least 2 GB (required).
• UART for serial console (required).
• Non-volatile memory, for example, QSPI flash and SD/MMC. This memory is optional but only JTAG boot can work.
• Ethernet (optional, essential for network access).

Zynq-7000 Devices

The following is a list of hardware requirements for a Zynq-7000hardware project to boot Linux:

• One Triple Timer Counter (TTC) (required).
  Important: If multiple TTCs are enabled, the Zynq-7000 Linux kernel uses the first TTC block from the device tree. Please make sure the TTC is not used by others.
• External memory controller with at least 512 MB of memory (required).
• UART for serial console (required).
• Non-volatile memory, for example, QSPI flash and SD/MMC. This memory is optional but only JTAG boot can work.
• Ethernet (optional, essential for network access).

MicroBlaze processors (AXI)

The following is a list of requirements for a MicroBlaze™ ™ hardware project to boot Linux:

• IP core check list:
  • External memory controller with at least 512 MB of memory (required)
  • Dual channel timer with interrupt connected (required)
  • UART with interrupt connected for serial console (required)
  • Non-volatile memory such as Linear Flash or SPI Flash (required)
  • Ethernet with interrupt connected (optional, but required for network access)
• MicroBlaze processor configuration:
  • MicroBlaze processors with MMU support by selecting either Linux with MMU or low-end Linux with MMU configuration template in the MicroBlaze configuration wizard.
    Note: Do not disable any instruction set related options that are enabled by the template, unless you understand the implications of such a change.
  • MicroBlaze processor initial boot loader fs-boot needs minimum 4 KB of block RAM for parallel flash and 8 KB for SPI flash when the system boots from non-volatile memory.
