《安富莱嵌入式周报》第302期：芯片内部Flash读保护攻击，开源智能手表设计，超棒静电学手册中文版，65W USB电源适配器方案，历届Matlab挑战赛

1，芯片内部Flash读保护攻击

Shedding too much Light on a Microcontroller’s Firmware Protection - Fraunhofer AISEC

发布于第11届USENIX进攻技术研讨会

经常有网友咨询设置芯片的读写保护是否安全，这个文章进行了详细攻击说明。通过这篇文章主要是想告诉大家，追求固件安全，仅靠设置读保护是不行的

可以考虑再配合下固件加密：

单片机BootLoader的AES加密实战，含上位机和下位机代码全开源

2，全开源基于Zephyr的智能手表设计

GitHub - jakkra/ZSWatch: ZSWatch - the Open Source Zephyr™ based Smartwatch, including both HW and FW.

硬件规格：

效果：

3，大量关于嵌入式系统笔记和讲义汇总

Embedded System Lecture Notes (cmu.edu)

资料非常多，干货也不少，唯一缺点都是英文的

部分截图：

4，LK(Little Kernel)嵌入式OS

GitHub - littlekernel/lk: LK embedded kernel

LK是面向多核应用的嵌入式OS，支持单片机和MPU，包括当前的电脑CPU都是支持的。

大家有兴趣可以了解下：

5、一款简单易用的ESP32开源开发工具ESP32 MPY-Jama，支持跨平台

GitHub - jczic/ESP32-MPY-Jama: New UI tool for manage Espressif ESP32 microcontrollers with embedded MicroPython for Windows & MacOS (IDE, files manager, REPL, real-time dashboards, advanced features, ...).

提供IDE，文件管理，实时仪表和高级功能

6、STM32C0的ThreadX软件包也要来了

上期周报给大家分享了STM32C0，主要是用于替代一些用8bit单片机的场合。

看下面的框图介绍，STM32C0的ThreadX软件包也要来了

7、静电学手册中文版

冬季静电电击很频繁，正在想办法，搜到一本《静电学手册》 - 综合资料 - 硬汉嵌入式论坛 - Powered by Discuz!

感谢坛友emwin的分享，手册非常棒，图文并茂言简意赅

8、历届Matlab Simulink学生挑战赛

10、I2C总线的光耦隔离

https://toshiba.semicon-storage.com/content/dam/toshiba-ss-v3/master/en/semiconductor/design-development/innovationcentre/whitepapers/TCM0646_Toshiba_Isolated_I2C_Communications_Using_Optoisolators.pdf

这篇笔记是东芝分享的，实现5KV隔离

主要注意增加光耦后对时许延迟的影响

11、TOP40 Python库

13、ST推出的65W USB电源适配器方案

EVLONEMP - Very high power density board - 65W multi-port (USB Type-C and USB Type-A) power delivery based on ST-ONEMP and MASTERGAN4 - STMicroelectronics

该板基于ST-ONEMP设计，ST-ONEMP是业界首款在单个封装中嵌入Cortex M0+内核的数字控制器、具有同步整流功能的离线可编程控制器和USB PD PHY。

规格

效果：

14、H7-TOOL本周进展

H7-TOOL详细介绍：H7-TOOL开发工具，1拖4/16脱机烧录，高速DAPLINK，RTOS Trace，CAN/串口助手, 示波器, RTT等，支持WiFi，以太网，高速USB和手持 - H7-TOOL开发工具 - 硬汉嵌入式论坛 - Powered by Discuz!

（1）添加新的脱机烧录芯片支持

（2）H7-TOOL Trace首版要支持的几款RTOS功能即将收尾

当前RTX5，uCOS-III和ThreadX已经没问题了，FreeRTOS差不多也完成了，这里要介绍的是：FreeRTOS Trace的通信组件部分不适合检索
FreeRTOS内核相关信息的Trace本身就已经比较繁琐。如果是程序主动输出(RTT或者EVR方式)，那就简单很多。但我们这里需要被动检索，这就麻烦很多了。

内核的Trace差不多已经成型
