u-boot下 /lib_arm/board.c 修改

#define GPD0DAT                           0xE02000A4 <==不能這樣寫,他讀到的是值,非位址

出現以下錯誤
board.c: In function 'buzzer_on':
board.c:225: error: lvalue required as left operand of assignment
board.c: In function 'buzzer_off':
board.c:234: error: lvalue required as left operand of assignment

#define GPD0DAT                            __REG(0xE02000A4)<==改成這樣變成指標指向位址
