SmashTV Core STM32F4 SDCARD questions

[flyweight]

I have a hard time accesing the sd card via MIOS.

 

Does access to the SD card work via MIOS studio when only the coreboard and STM32F4Discovery and SDcard are connected?

 

All pins are connected ok.

 

9 NC

1 PB2

2 PA7

3 GND

4 VDD 3v

5 PA5

6 GND

7 PA6

8 NC

 

SD cards Shield connected to GND

When connected to micro usb LD1 is blinking.

When ejecting or inserting the SD card nothing hapens.

3 v is available on pin 4 and 2 data lines

 

The correct IC's in the sockets, the resistor network connect with common pin on 1.

 

After flashing the seq4 app should some jumpers be removed?

Connection looks good, except that pin 9 has also to be connected to GND.

No jumpers need to be removed.

i found out that pin 9 is indeed connected to GND.

Still via MIOS studio i am not able to mount the sdcard.

My sdcard is 2GB formated with FAT32. 

 

Could it be that the card works but only not via MIOS studio?

 

If fully checked the coreboard and there arn't any mistakes to be found.

 

Any how i ordered a new sdcard socket as i thought it might be faulty i removed it, during that i found out it was 100% ok :(

 

If you only have the coreboard and stm32f4 can you access the SDcard via mios studio?

Hi,

 

you've to upload a firmware which supports SD Card operations, such as MIDIbox SEQ, MIDIBox NG, MIDIO128, ...

These firmwares also provide special debug commands (enter "help" in the MIOS terminal), e.g. "sdcard" to get the SD Card status.

Hi Thorsten,

Indeed the sdcard command failed, i just soldered another sdcard socket and it works!  I am really happy that i didn't braek anything while troubleshooting.   Still don't know what was so different with the socket which didn't work, but still really happy that it works now.

 

Thanks all,

 

Best regards,
