== Introduction ==

RK3399Pro is made of two blocks, RK3399 and the NPU. The RK3399, running Linux or Android is the host, and the NPU running Linux is the device.
The host controls the power of NPU and the NPU firmware updating. Firmware updating is via USB2.0 and the model data transfer between host/device via USB 3.0.

== NPU tools and utilities ==
=== Boot Service ===
The npu_upgrade service, powering the NPU and NPU firmware upgrading:

<syntaxhighlight lang="bash">

root@linaro-alip:~# cat /etc/init.d/rockchip.sh function update_npu_fw() {
/usr/bin/npu-image.sh
sleep 1 /usr/bin/npu_transfer_proxy&
}
root@linaro-alip:~# cat /usr/bin/npu-image.sh
npu_upgrade MiniLoaderAll.bin uboot.img trust.img boot.img

</syntaxhighlight>

=== Powering Control ===
'''npu_powerctrl''' is the binary utility to control the NPU power by toggle the GPIO of NPU power.

/usr/bin/npu_powerctrl -i
/usr/bin/npu_powerctrl -o

If the NPU power is on, on the host side, the USB device(ID: '''180a''') will be detected, NPU is in '''maskrom''' mode.

[ 4.437235] usb 3-1: New USB device found, idVendor=2207, idProduct=180a

<syntaxhighlight lang="bash">

root@linaro-alip:~# npu_powerctrl Usage:npu_powerctrl [-s] [-r] [-o] [-i] [-d]
-s -r -o -i
npu enter sleep wakup npu
power up or reset npu gpio init
</syntaxhighlight>

=== Firmware upgrading ===
npu_upgrade is the tool for downloading the firmware to NPU ram.

NPU firmware path: DIR="/usr/share/npu_fw"
Tool path: UPGRADE_TOOL=/usr/bin/upgrade_tool

After firmware finish downloading, the NPU will boot automatically.

=== NPU troubleshooting ===
==== 1. NPU sleep and USB enumerating ====
On the host:

[ 14.265132] usb 4-1: New USB device found, idVendor=2207, idProduct=1808

Check the device status and wake up manually
<syntaxhighlight lang="bash">

root@linaro-alip:~# npu_powerctrl -s # Manually sleep npu
root@linaro-alip:~# lsusb # No USB device if the npu is sleep
root@linaro-alip:~# npu_powerctrl -r # Manually wakeup npu
root@linaro-alip:~# lsusb
Bus 004 Device 003: ID 2207:1808
