ChibiOS Free Embedded RTOS

Thank u for the reply.
I formatted it in windows machine . It is fat32. it is 2 gb sandisk microsd. i partitioned it into two.

Sorry, I didn't see ur previous reply.

Any hekp please?

I tried other cards but they dont even mount the card. When I debug the function (which gives me error), I released that I get:
FR_NO_FILESYSTEM, /* (13) There is no valid FAT volume on the physical drive */
error.

/*static*/
FRESULT chk_mounted ( /* FR_OK(0): successful, !=0: any error ...

I have Sandisk microsd card. It gives me error in ff.c file. chk_mounted :which checks if the file system object is valid or not. it cannot verify...

static void cmd_tree(BaseChannel *chp, int argc, char *argv[]) {
FRESULT err;
uint32_t clusters;
FATFS *fsp;

(void)argv;
if (argc > 0) {
chprintf(chp, "Usage: tree\r\n");
return;
}
if (!fs_ready) {
chprintf(chp, "File System not mounted\r\n");
return;
}
err = f_getfree ...

Hi,
I am using stm32f407-DISCOVERY board (VGT6) . I use arm-none-abi-gcc toolchain. I use a demo application in ChibiOS. I added the fatfs library to the demo example. I use SPI communication. (PA 5-6-7 and PC4 as chip select). I change the halconf.h file to support MMC-SPI.

Thank you!

Hello,
I am trying to use my microsd card with stm32f4-DISCOVERY board. I can mount the sd card but I get "f_getfree failed" error, when I try to read something from the sd card. I am using ChibiOS 2.4.3 . I programmed the card as fat32.


Thank you,
