YuzukiXR32 调试日记：SD卡驱动调试

[YuzukiTsuru]

首先，SDK抄一下EVB的相关文件

然后把 __PRJ_CONFIG_BOARD 修改到 __PRJ_CONFIG_BOARD := YuzukiXR32

试试能不能编译编译

cd XR32SDK/project/example/sd/gcc
make build

编译通过~

    ]
}

刷写程序

运行一下试试看

不出所料，用不了，应该是引脚绑定不同，打开板级文件看看

__xip_rodata
static const GPIO_PinMuxParam g_pinmux_sd0[BOARD_SD0_DATA_BITS + 2] = {
	{ GPIO_PORT_A, GPIO_PIN_0,  { GPIOA_P0_F3_SD_CMD,     GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* CMD */
	{ GPIO_PORT_A, GPIO_PIN_2,  { GPIOA_P2_F3_SD_CLK,     GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* CLK */
	{ GPIO_PORT_A, GPIO_PIN_1,  { GPIOA_P1_F3_SD_DATA0,   GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* D0 */
//	{ GPIO_PORT_A, GPIO_PIN_3,  { GPIOA_P3_F3_SD_DATA1,   GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* D1 */
//	{ GPIO_PORT_A, GPIO_PIN_4,  { GPIOA_P4_F3_SD_DATA2,   GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* D2 */
//	{ GPIO_PORT_A, GPIO_PIN_5,  { GPIOA_P5_F3_SD_DATA3,   GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* D3 */
};

果然，绑定的脚是PA的SD脚位，参照YuzukiXR32的电路图，应该是使用PB驱动SDIO才对。

那就修改一下

__xip_rodata
static const GPIO_PinMuxParam g_pinmux_sd0[BOARD_SD0_DATA_BITS + 2] = {
	{ GPIO_PORT_B, GPIO_PIN_4,  { GPIOB_P4_F3_SD_CMD, GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* CMD */
	{ GPIO_PORT_B, GPIO_PIN_7,  { GPIOB_P7_F3_SD_CLK,  GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* CLK */
	{ GPIO_PORT_B, GPIO_PIN_5,  { GPIOB_P5_F3_SD_DATA0, GPIO_DRIVING_LEVEL_2, GPIO_PULL_UP } },	/* D0 */
};

成功运行
