查閱了很多資料，關於這個28377芯片的貢獻實在有點少，可能大師們自己知道並不願意分享吧！第一次發帖，很緊張。。>_<。
本人使用的編譯器爲CCS v8.3.0 ，關於W5500的資料早已爛大街了，這裏主要對官方tftp傳輸稍作修改（個人官方tftp狀態機很亂，詳細參考:https://w5500.com/code.html） , 話不多說，上代碼：

以上爲tftp協議部分 ，配合pc端軟件 tftpd32 即可快速文件傳輸，因DSP flash擦除和編程時不能訪問flash，內部SRAM容量有限，這裏我將接收的app.bin文件數據放入外部SDRAM，下一步將SDRAM數據copy到內部flash即可，(因uboot佔用bank0 ，所以只能將bnak1作爲app使用)以下爲編程flash代碼：
