[i=s] 本帖最后由 yqzq101 于 2024-10-16 09:44 编辑 [/i] hello 立创上请了一块谅山派的F4A0开发板。。 发现rt-studio里面居然有这个开发板的支持 试着创建了工程,闪了个灯一切OK 想测试一下tf卡, 按照网上搜的例子, 打开了SDIOC1, 加了fatfs, 下载后,总提示如下: msh />[E/drv.sdio] clock division error [E/drv.sdio] clock division error [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 0, arg:0x00000000 [E/drv.sdio] clock division error [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 8, arg:0x000001AA clock division error[E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 5, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 55, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 55, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 55, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 55, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 1, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 1, arg:0x00000000 [E/drv.sdio] [_sdio_wait_completed timeout] sta=0x1FFE82A0, cmd 1, arg:0x00000000 请问这是为啥。。是我哪里没改好吗 谢谢
