硬件设备及镜像
主板为：Yuzuki Lizard V851S开发板
宿主机环境：ubuntu 22.04
SDK版本：Yuzukilizard的github上的Docker镜像
img为：github上Yuzukilizard释放的镜像：[01]v851s_linux_lizard_uart0_2022_12_29.img v851s_linux_lizard_uart0_2022_12_29.img
问题现象简述：
- sdc0报错：
sunxi-mmc sdc0: smc 0 p0 err, cmd 8, RTO !!
sunxi-mmc sdc0: smc 0 p0 err, cmd 55, RTO !!
- sdc1报错：
sunxi-mmc sdc1: smc 1 p1 err, cmd 5, RTO !!
sunxi-mmc sdc1: smc 1 p1 err, cmd 52, RTO !!
- /dev下无sdc0的mmcblock设备TF卡故障，但是sdc1的WiFi部分工作正常
- 已确认此TF卡可在其他设备上正常读取，TF卡分为两个分区：第一分区FAT32——2GB，第二分区EXT4——2GB
已尝试过的方法
- 用Yuzukilizard的github上的Docker直接编译镜像，烧录后故障仍存在。❌
- 更换过Yuzukilizard在github上直接释放的不同镜像，均无效。❌
- 尝试按照Tina SDK文档更改board.dts、uboot-board.dts、sys_config.fex的sdc0和card0部分以及make menuconfig和make kernel_menuconfig，编译烧录无效。❌
- 尝试在board.dts中追加vmmc regulator等配置，编译烧录后无效。❌
- 更换不同的TF卡，和不同的文件系统尝试过FAT32和EXT4均为2GB，故障依旧。❌
- 尝试更换不同的SDK和Ubuntu版本，无效。❌
- 用示波器测试TF卡的CMD信号脚，信号正常发出。

问题分析思路：
- 检查一下这个img镜像是否开启了TF卡的读写功能？
- 确定一下这个问题出现在哪一个方面，①设备树配置问题？②SDK工具和环境问题？③硬件问题？
.
github上释放的镜像并没有开启TF卡的读写功能！需要自行更改board.dts并编译打包烧录！
解决方法
4. 修改board.dts如下位置
sdc0_pins_a: sdc0@0 {
allwinner,pins = "PF0", "PF1", "PF2",
"PF3", "PF4", "PF5";
allwinner,function = "sdc0";
allwinner,muxsel = <2>;
- allwinner,drive = <1>;
+ allwinner,drive = <3>;
- allwinner,pull = <0>;
+ allwinner,pull = <1>;
};
&sdc0 {
- /*cd-gpios = <&pio PF 6 6 1 3 0xffffffff>;*/
+ cd-gpios = <&pio PF 6 6 1 3 0xffffffff>;
- /*cd-used-24M;*/
+ cd-used-24M;
};
- 检查Kernel Configuration是否设置正确，这些选项已在docker镜像中默认配置好
i. 确认Device Drivers的设置下的MMC/SD/SDIO card support设置为开启
ii. 设置 MMC/SD/SDIO card support ——> Number of minors per block device 为 8
iii. 确认MMC/SD/SDIO card support ——> MMC block device driver 和 Allwinner sunxi SD/MMC Host Controller support设置为开启
iv. 确认File systems下开启对ext4文件系统和VFAT文件系统的支持
三. 仍存在问题
- tf卡不支持热插拔，一但拔出需要重启系统
- sdc1仍然报错，但是wifi部分正常
- tf卡时不时就报以下错误
