Seagate FireCuda Gaming SSD (FaZe) board

Overview

The FaZe board can be found in the Seagate FireCuda Gaming SSD devices. A NVMe SSD and two chips are embedded: an ASMedia ASM2364 USB-to-PCIe bridge controller and a NXP LPC11U67 MCU. The former is handling the USB type-C to SSD I/Os while the latter is dedicated to the LED effects. The two chips are connected together through I2C and GPIOs.

This Zephyr port is running on the NXP LPC11U67 MCU.

Hardware

  • NXP LPC11U67 MCU (LQFP48 package):

    • ARM Cortex-M0+

    • 20 KB SRAM: 16 KB (SRAM0) + 2 KB (SRAM1) + 2KB (USB SRAM)

    • 128 KB on-chip flash

    • 4 KB on-chip EEPROM

  • External devices connected to the NXP LPC11U67 MCU:

    • ASMedia ASM2364 USB-to-PCIe bridge (I2C master on port O).

    • 6 RGB LEDs connected connected to a TI LP5030 LED controller (I2C device on port 1).

    • 1 white LED (SSD activity blinking).

Programming and Debugging

Flashing

The NXP LPC11U67 MCU can be flashed by connecting an external debug probe to the SWD port (on-board 4-pins J2 header). In the default OpenOCD configuration (boards/arm/faze/support/openocd.cfg) the ST Link interface is selected. You may need to replace it with the interface of your debug probe.

Once the debug probe is connected to both the FaZe board and your host computer then you can simply run the west flash command to write a firmware image you built into flash.

Debugging

Please refer to the Flashing section and run the west debug command instead of west flash.
