内核正常启动后，无法正常挂载sd卡
问题：使用的从贵公司购买的公板以及rk3588sJD4核心板，烧录的也是官方提供的固件。进入文件系统后，发现sd卡节点为mmcblk1p1 ，通过指令mount -o sync /dev/mmcblk1p1 /mnt/sd/ 挂载sd卡报错：
[ 54.822552] FAT-fs (mmcblk1p1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
mount: mounting /dev/mmcblk1p1 on /mnt/sd/ failed: Invalid argument
请问内核是需要配置哪里，才能正常挂载sd卡吗？
