1，芯片内部Flash读保护攻击

https://www.aisec.fraunhofer.de/en/FirmwareProtection.html

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

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

4，LK(Little Kernel)嵌入式OS

https://github.com/littlekernel/lk

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：

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

https://www.st.com/en/evaluation-tools/evlonemp.html

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：https://www.armbbs.cn/forum.php?mod=viewthread&tid=89934

（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
