RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?
@night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

RE: RKDevTool和rkdeveloptool的功能区别
@zehui
1.目前硬件是强制SPI启动的,如下图硬件配置,如果要改为扫描启动方式,可以去掉R18的电阻。
2.目前使用的是rockchip的loader和uboot。github的uboot源码有包括SPL部分。用户可以自行修改,DDRBIN目前没有开放源码只有二进制文件。 -
RE: RKDevTool和rkdeveloptool的功能区别
@zehui
目前ARM平台的升级工具只有rkdeveloptool,github的这个工具是很老的版本,还不支持多存储设备的升级。- 如果是ARM64的ubuntu系统,coolpi4b机器进入UMS模式,然后双击img镜像文件,选择对应的UMS设备就可以升级。
- github有etcher的源码,也可以编译生成ARM64的版本用于系统升级。
- 也可以把ubuntu系统做到u盘,然后使用u盘启动,然后双击img镜像也可以刷到EMMC,或者TF卡。

RE: 4b会支持rkllm版本么?
@airobot机器人开发
目前还是beta版本,等后续的release版本再考虑移植。如果有兴趣可以自己尝试移植,里边最主要的步骤是X86上面的模型转换过程。需要更详细资料可以邮件索取:george@cool-pi.com -
RE: 4b会支持rkllm版本么?
Description
RKLLM software stack can help users to quickly deploy AI models to Rockchip chips. The overall framework is as follows:
In order to use RKNPU, users need to first run the RKLLM-Toolkit tool on the computer, convert the trained model into an RKLLM format model, and then inference on the development board using the RKLLM C API.
-
RKLLM-Toolkit is a software development kit for users to perform model conversionand quantization on PC.
-
RKLLM Runtime provides C/C++ programming interfaces for Rockchip NPU platform to help users deploy RKLLM models and accelerate the implementation of LLM applications.
-
RKNPU kernel driver is responsible for interacting with NPU hardware. It has been open source and can be found in the Rockchip kernel code.
Support Platform
- RK3588 Series
- RK3576 Series
Download
- You can also download all packages, docker image, examples, docs and platform-tools from RKLLM_SDK, fetch code: rkllm
RKNN Toolkit2
If you want to deploy additional AI model, we have introduced a new SDK called RKNN-Toolkit2. For details, please refer to:
https://github.com/airockchip/rknn-toolkit2
Notes
Due to recent updates to the Phi2 model, the current version of the RKLLM SDK does not yet support these changes.
Please ensure to download a version of the Phi2 model that is supported.CHANGELOG
v1.0.0-beta
- Supports the conversion and deployment of LLM models on RK3588/RK3576 platforms
- Compatible with Hugging Face model architectures
- Currently supports the models LLaMA, Qwen, Qwen2, and Phi-2
- Supports quantization with w8a8 and w4a16 precision
