board/st2410/st2410.c (cp from smdk2410) 自作聪明写下 #define FCLK_SPEED 2 #define USB_CLOCK 2 然在原本的 #if FCLK_SPEED==0 /* Fout = 203MHz, Fin = 12MHz for Audio */ #define M_MDIV 0xC3 #define M_PDIV 0x4 #define M_SDIV 0x1 #elif FCLK_SPEED==1 /* Fout = 202.8MHz */ #define M_MDIV 0xA1 #define M_PDIV 0x3 #define M_SDIV 0x1 后面添加 #elif FCLK_SPEED==2 ...(设置200M/100M/50M) #endif 几句话,试图重新修改MPLL和UPLL频率 然后烧录后发现不行,压根没动,示波器测量还是202.8M 嘿嘿嘿, 哪位高人谁能一眼看出来问题啊?小弟来拜一拜 |
