網(wǎng)上有很多關(guān)于pos機(jī)代碼77,零代碼玩轉(zhuǎn)OTA升級(jí)的知識(shí)，也有很多人為大家解答關(guān)于pos機(jī)代碼77的問題，今天pos機(jī)之家(www.rcqwhg.com)為大家整理了關(guān)于這方面的知識(shí)，讓我們一起來看下吧!

pos機(jī)代碼77
前言： 當(dāng)了解了stm32通用bootloader的實(shí)現(xiàn)方法，今天給大家在bootloader的基礎(chǔ)上，介紹app如何通過多種固件下載器實(shí)現(xiàn)OTA升級(jí)。
先看下演示視頻，此視頻演示了四種升級(jí)方式，分別是：
阿里云物聯(lián)網(wǎng)平臺(tái)OTAHTTP OTAYmodem OTA不用app，使用Bootloader中的Ymodem OTA此項(xiàng)目硬件使用的是STM32F429開發(fā)板，代碼全部使用RT-Thread Studio搭積木的方式實(shí)現(xiàn)，僅僅改動(dòng)了幾行代碼，開發(fā)效率非常高。此項(xiàng)目的地址：https://gitee.com/Aladdin-Wang/RT-FOTA-STM32L431.git
使用到的軟件包和組件：
在這里插入圖片描述
1.準(zhǔn)備工作1.1 新建工程由于此項(xiàng)目使用的esp8266需要一個(gè)串口，我使用的是uart2，所以需要還需要配置uart2：
增加uart接收緩沖區(qū)大?。?/strong>
1.2 打開fal和at device軟件包配置fal軟件包
配置sfud組件
配置SPI
配置fal_cfg.h

2.阿里云物聯(lián)網(wǎng)平臺(tái)OTA注冊(cè) LinkPlatform 平臺(tái)
創(chuàng)建產(chǎn)品
產(chǎn)品詳情：
添加設(shè)備
添加自定義Topic
配置ali iotkit軟件包將剛才新建的阿里云設(shè)備信息填寫到配置信息里：
將軟件包的示例mqtt-example.c和ota_mqtt-example.c拷貝到applications目錄備用
配置mbedtls軟件包
更改ota_mqtt-example.c中的部分代碼：

編譯工程，將bin文件上傳到阿里云：阿里云不支持rbl格式的文件，直接將rt_ota_packaging_tool生成的rbl文件后綴改為bin，上傳即可。
最后使用ali_ota_sample命令升級(jí)：
3.HTTP OTA和Ymodem OTA配置ota_downloader軟件包
如果暫時(shí)沒有自己的服務(wù)器，可以使用MyWebServer進(jìn)行測試：
配置完MyWebServer，可以打開瀏覽器輸入IP地址查看：
使用http_ota命令進(jìn)行http_ota升級(jí)：
使用ymodem_ota命令進(jìn)行ymodem_ota升級(jí)：
4.不使用APP進(jìn)行升級(jí)rt-fota集成了ymodem_ota，上電短按恢復(fù)出廠設(shè)置按鈕即可進(jìn)入rt-fota命令行模式，通過ymodem_ota命令即可進(jìn)行升級(jí)：
