上一篇配置好了开发环境,现在就可以试着跑一下例程了,这里需要两个例程,一个是bootloader的,一个是应用程序的,其路径分别为: bootloader:SDK_14.2.0工程\examples\dfu\bootloader_secure_ble\pca10040\arm5_no_packs 应用程序:SDK_14.2.0工程\examples\ble_peripheral\ble_app_buttonless_dfu\pca10040\s132\arm5_no_packs 这里用到了一些工

本文将详述Nordic nRF51系列(包括nRF51822/nRF51802/nRF51422等)和nRF52系列(包括nRF52832/nRF52810/nRF52840)开发环境搭建. 1. 强制安装项 如下工具必须安装,否则无法开发Nordic nRF51/52产品 安装IDE.Nordic nRF51/52支持Keil,GCC,IAR和SES(Segger Embedded Studio)四种IDE,大家随便选择其中一种安装即可. Keil.大家自行下载安装,这里不再赘述. IAR.大

1. 在lowlevel_init过程中,本来想实现一个串口直接打印字符串的过程,编译的时候出现了问题,说是发现代码执行段没有对齐:“unaligned opcodes detected in executable segment”.开始的时候随便找了几个地方加上 .align 4, 并没有用,后来发现原因是字符串的长度不是字长的整数倍,比如: uart_init_ok_log: .string "hello world!\r\n",由于该字符串会自动加上结束符,因此该字符串的长度是1

如何实现BLE OTA?什么叫DFU?如何通过UART实现固件升级?又如何通过USB实现固件升级?怎么保证升级的安全性?什么叫双备份(dual bank)DFU?什么叫单备份(single bank)DFU?什么叫后台式(background)DFU?本文将对上述问题进行探讨. 1.概述 所谓DFU(Device Firmware Update),就是设备固件升级的意思,而OTA是DFU的一种类型,准确说,OTA的全称应该是OTA DFU,只不过大家为了方便起见,直接用OTA来指代固件空中升级(

摘要:在前面的nrf52--DFU升级OTA升级方式详解(基于SDK开发例程)一文中我测试了基于蓝牙的OTA,本文将开始基于UART和USB(USB_CDC_)进行升级测试. 整体升级流程: 整个过程希望你和我一样采用有log的bootloader进行.可以看到执行流程,也能在出错时进行检查. 1.生成秘钥(一定要保留好) 2.生成USB或者UART的BootLoader程序(需要算法库和秘钥) 3.生成APP工程 4.合成初始的固件.并下载到相应的硬件 5.生成需要更新的APP固件 6.合成升

在我们开始前,默认你已经安装好了一些基础工具,如nrfutil,如果你没有安装过请根据官方中文博客去安装好这些基础工具,连接如下:Nordic nRF5 SDK开发环境搭建(nRF51/nRF52芯片平台) - iini - 博客园 (cnblogs.com) 本文只是对整个升级过程进行一次完整操作,以及其中可能出错的地方进行记录,如果你想知道具体原理,那么请你看官方中文博客的两篇文章,如果仅仅只是基于SDK,那么你参考第一篇即可,如果你需要在NCS上进行请参考第二篇,相信你在看了该博客后会对D

今天在使用svn时发现有好多不认识了,所以查了下svn帮助手册.借此总结了下 svn 中图标的含义 一个新检出的工作复本使用绿色的勾做重载.表示Subversion状态 正常. 在开始编辑一个文件后,状态就变成  已修改,而图标重载变成了红色感叹号.通过这种方式,可以很容易地看出那些文件从你上次更新工作复本后被修改过,需要提交. 如果在提交的过程中出现了 冲突  图标变成黄色感叹号. 如果你个一个文件设置了 svn:needs-lock属性, Subversion 会让此文件只读,直到你获得文件
