Hardware
--------

- HPM6360IPA MCU
- Onboard Memory

  - 16bit 256Mb SDRAM
  - 128Mb Quad SPI NOR Flash

- USB

  - USB type C (USB 2.0 OTG) connector x2

- Ethernet

  - 100Mb PHY

- Others

  - TF Slot
  - CAN FD
  - FT2232

- Expansion port

  - Motor control port
  - Raspberry PI extension port

.. note::

   The sdram pins are multiplexed with the 15-20pin of the motor interface J26, so the motor interface and sdram can't be used at the same time.

Board Know Issue
----------------------

- USB VBUS pin resistance issue

  - Impact

    - This issue may affect the Host's ability to enumerate USB as a device.

  - Solution

    - Replace the 1kohm resistors R135 with 10ohm resistors.

       :alt: hpm6300evk_known_issue_1

  - Revised Status

    - `HPM6300EVKRevD` has been revised, `HPM6360-EVK-A3` and previous versions have this issue.

- USB ID pin pull down resistance issue

  - Impact

    - When using USB OTG, this issue may affect the role recognition of USB connected device or connected host.

  - Solution

    - Remove the pull-down resistors R127, R128 from the CC port of the USB interface.
