開發板選擇
stm32mpu wiki的General Books使用了兩款STM32MP1開發板作爲演示講解，STM32MP157x-EV1和STM32MP157C-DK2，由於STM32MP1是比較新的東西，自己對Linux開發也不熟，爲了避免在學習過程中遇到遇到過多的問題，所以選擇購買和教程一致的開發板。STM32MP157x-EV1在某寶上就可以買到，價格3500左右，對我來說價格太貴了，所以不考慮。STM32MP157C-DK2屬於禁運商品，所以不太好購買，可以讓代理商代購，價格在1500左右，貨期2周，價格還能接受，所以我購買的STM32MP157C-DK2開發板。
開發板介紹
經過兩週的等待，設備到手了，總共4樣東西，STM32MP157C-DK2 Discovery kit一套，16GB MicroSD一張，USB TypeC to USB TypeC線一根，一份說明書。如下圖所示：
接口說明，如下圖所示：
1
1、CN6爲供電接口，USB TypeC接口，需要使用5V 3A供電，可以使用USB A接口的電源適配器+USB A轉USB TypeC連接線給開發板供電，一般手機的充電器就行，也可以使用USB TypeC接口的電源適配器+USB TypeC to USB TypeC線供電，目前在一些筆記本使用此類充電器。
2、CN11爲調試接口，Micro USB接口，連接開發板自帶的ST-Link/V2-1仿真器，用於燒寫固件，UART調試，ST-Link/V2-1的USB轉UART連接了STM32MP157C的UART Debug接口，所以可以通過ST-Link/V2-1的COM接口輸入命令，查看調試信息，波特率115200，數據位8位，停止位1位，無奇偶檢驗。
3、CN7爲USB OTG接口，USB TypeC接口，用於連接鼠標、鍵盤、U盤等USB外設，需要USB TypeC轉USB A母頭的轉接頭配合使用。
4、CN8位千兆以太網口，RJ45接口，可以通過此接口連接到網絡，通過SSH調試開發板。
開發板測試
1、電腦使用Windows系統，使用一根USB A轉MicroUSB的連接線，USB A插入電腦的USB口，MicroUSB插入CN11，如果電腦沒有ST-Link/V2-1的驅動，需要先安裝驅動，ST官方驅動下載鏈接：https://www.st.com/content/st_com/zh/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-utilities/stsw-link009.html；
網盤驅動下載鏈接：https://pan.baidu.com/s/1FOvDOXQRzq63wc4Vc93LWA 提取碼：vum5 ；驅動安裝好之後，打開電腦的設備管理器（鼠標右鍵我的電腦->管理->設備管理器），可以看到端口（COM和LPT）下面有STMicroelectronics STLink Virtual COM Port，通用串行總線設備下面有ST-Link Debug，如下圖所示：
2、運行SecureCRT軟件，鼠標右鍵Sessions->New Session，Protocol選擇Serial，單擊下一步，Port選擇STLink Virtual COM POrton的編號（如COM28），Baud rate：115200，Data bits：8，Parity：None，Stop bits：1，然後點擊下一步，點擊完成，Sessions下面會有一個新的Session名稱，雙擊此名稱，會連接到開發板。如果沒有安裝此軟件，需安裝後再進行操作，也可使用其它終端軟件。
3、給開發板供電，開發板上的顯示屏會有顯示界面，SecureCRT Session會顯示啓動Log，如下圖所示：
