.. zephyr:board:: acp_6_0_adsp | ||
Overview | ||
******** | ||
|
||
ACP 6.0 is Audio co-processor in AMD SoC based on HiFi5 DSP Xtensa Architecture, | ||
Zephyr OS is ported to run various audio and speech use cases on | ||
the SOF based framework. | ||
|
||
SOF can be built with either Zephyr or Cadence's proprietary | ||
Xtensa OS (XTOS) and run on a ACP 6.0 AMD platforms. | ||
|
||
Hardware | ||
******** | ||
|
||
- Board features: | ||
|
||
- RAM: 1.75MB HP SRAM & 512KB configurable IRAM/DRAM | ||
- Audio Interfaces: | ||
|
||
- 1 x SP (I2S, PCM), | ||
- 1 x BT (I2S, PCM), | ||
- 1 x HS (I2S, PCM), | ||
- DMIC | ||
|
||
Supported Features | ||
================== | ||
|
||
The following hardware features are supported: | ||
|
||
+-----------+------------+-------------------------------------+ | ||
| Interface | Controller | Driver/Component | | ||
+===========+============+=====================================+ | ||
| I2S | on-chip | I2S controller | | ||
+-----------+------------+-------------------------------------+ | ||
| DMIC(PDM) | on-chip | PDM controller | | ||
+-----------+------------+-------------------------------------+ | ||
|
||
System Clock | ||
============ | ||
|
||
The ACP 6.0 SoC operates with an audio clock frequency ranging from 200 to 800 MHz. | ||
|
||
System requirements | ||
******************* | ||
|
||
Xtensa Toolchain (optional) | ||
=========================== | ||
|
||
The Zephyr SDK provides GCC-based toolchains necessary to build Zephyr for | ||
the AMD ACP boards. For users looking for higher optimization levels, | ||
building with the proprietary Xtensa toolchain from Cadence | ||
might be preferable. | ||
|
||
The following instructions assume you have purchased and | ||
installed the toolchain(s) and core(s) for your board following | ||
instructions from Xtensa documentation. | ||
|
||
If you choose to build with the Xtensa toolchain instead of the Zephyr SDK, set | ||
the following environment variables specific to the board in addition to the | ||
Xtensa toolchain environment variable listed below. | ||
|
||
First, make sure, the necessary license is available from | ||
Cadence and set the license variables as per the instruction from Cadence. | ||
Next, set the following environment variables: | ||
|
||
The bottom three variables are specific to acp_6_0. | ||
|
||
.. code-block:: shell | ||
export XTENSA_TOOLCHAIN_PATH="tools installed path" | ||
export XTENSA_BUILDS_DIR="user build directory path" | ||
export ZEPHYR_TOOLCHAIN_VARIANT=xcc | ||
export TOOLCHAIN_VER=RI-2019.1-linux | ||
export XTENSA_CORE=LX7_HiFi5_PROD | ||
Programming and Debugging | ||

|
||
Building | ||
======== | ||
|
||
Build as usual. | ||
|
||
.. zephyr-app-commands:: | ||
:zephyr-app: samples/hello_world | ||
:board: acp_6_0_adsp/acp_6_0 | ||
:goals: build | ||
|
||
Flashing | ||
======== | ||
|
||
AMD supports only signed images flashing on ACP 6.0 platforms | ||
through ACP Linux Driver. | ||
|
||
The following boot sequence messages can be observed in dmesg | ||
|
