【程式】Marvell 88W8782/88W8801 WiFi模組的韌體下載程式碼

阿新 • • 發佈：2019-01-27

本程式所用的微控制器型號為：STM32F103VE

PB12接WiFi模組的復位引腳（RST），上電時RST=0先復位，然後RST=1開始工作。

所用的WiFi模組為：88W8801。雖然綠色的板子上面寫的是88W8782，但實際上中間的黑色晶片用的是88W8801。

【sd8801_uapsta.c：用於88W8801的韌體】

【sd8782_uapsta.c：用於88W8782的韌體】

出現odd size錯誤的，請在韌體陣列前面加__attribute__((aligned))語句，使陣列的首地址能夠被4整除。例如：
__attribute__((aligned)) const unsigned char firmware_helper_sd[2516];
