Question
FATFS_LinkDriver(&USER_Driver, USER_Path)==0) question ?
Posted on January 26, 2016 at 06:40
Guys,
Can I use SPI2 for SDcard with STM32CubeMX ? I can see from : #define HAL_SD_MODULE_ENABLED but there's no SPI implementation for it, it's for SDIO, and STM32F107 doesn't have SDIO... I tried to run if(FATFS_LinkDriver(&USER_Driver, USER_Path)==0) { HAL_UART_Transmit(&huart1, ''FATFS_LinkDriver OK! \r\n'', 55, 1000); // Debug if (f_mount(&FatFs, (TCHAR const*)USER_Path, 0)==FR_OK) { HAL_UART_Transmit(&huart1, ''F_MOUNT \r\n'', 55, 1000); // Debug if (f_open(&Fil, ''newfile.txt'', FA_WRITE | FA_CREATE_ALWAYS) == FR_OK) { HAL_UART_Transmit(&huart1, ''F_OPEN test_write..\r\n'', 15, 1000); // As a pointer, with a length if (f_write(&Fil, ''Test write line1 !\r\n'', 17, &bw) == FR_OK) /* Write data to the file */ { HAL_UART_Transmit(&huart1, ''F_WRITE 1 \r\n'', 55, 1000); // Debug //f_write(&Fil, ''Next line test\r\n'', 16, &bw); /* Write data to the file */ //HAL_UART_Transmit(&huart1, ''F_WRITE 2 \n\r'', 55, 1000); // Debug //HAL_UART_Transmit(&huart1, ''FWRITE \n\r'', 15, 1000); // As a pointer, with a length HAL_GPIO_WritePin(GPIOE, GPIO_PIN_6 , 0 ); HAL_Delay(5000); HAL_GPIO_WritePin(GPIOE, GPIO_PIN_6 , 1 ); } f_close(&Fil); /* Close the file */ HAL_UART_Transmit(&huart1, ''FCLOSE \r\n'', 15, 1000); // As a pointer, with a length } } } I can pass FATFS_LinkDriver(&USER_Driver, USER_Path)==0) but I can't continue to f_mount .... What's missing here ? I can not see my debug message in disk_initialize but it can give FR_OK ?? user_diskio.h extern Diskio_drvTypeDef USER_Driver; <== I got error ''unknown type Diskio_drvTypeDef'' on this line, but I can compile it, what should I fix ? user_diskio.cDiskio_drvTypeDef USER_Driver =

USER_write,
