Other Parts Discussed in Thread: OMAPL138, OMAP-L138
Hi,,
I have RTFS based MMCSD code for C6748 which I am using on OMAPL138 EVM with OMAPL138 SOM. It doesn't work when UI board is connected to the EVM and says MMC/SD card not present but as soon as I disconnect the UI board it executes the code.
What's wrong here ?
Thanks.
Tariq
Please see if the GPO[11] high/low mux for NOR vs SD/MMC could be impacting you
http://processors.wiki.ti.com/index.php/DaVinci_PSP_03.20.00.14_Release_Notes
Look for
SDOCM00075832
I didn't understand what you mean ? Where should I see that ? GPIO0DSP's IN_DATA01 register ? GP0P11 inside IN_DATA01 register is CLR with or without UI board. Code works without UI board but doesn't with UI board.
I am not booting from MMC/SD Card rather using MMCSD card to store data coming from A/D converter. EVM is booting from SPI flash at the moment.
Hi Tariq,
Kindly let us know which RTFS based MMCSD code you are trying to use. Is it the one from TI or your custom code?
From our understanding, it seems the code is running through CCS(is it correct?) and while the UI board is connected your code doesn’t work.
Here are some suggestions from our Hardware team.

Iyshwarya,
I am using OMAP-L138 EVM by LogicPD. I am using rtfs_1_10_02_32 package for EVM6748. Yes I am using CCS V. 4.2.0 and you are correct that the code doesn't work while the board is connected. If there was a problem with PINMUX, it wouldn't have run without UI board.
I am attaching GEL file as text file, please have a look.

Hi Tariq,
Did you get it to work? I'm having the same problem as the one you described in "http://e2e.ti.com/support/embedded/bios/f/355/t/234760.aspx", where it doesn't recognize the card. That is, I'm getting the error message "Please insert the card". I'm using a 2G SD card.
If you have managed to solve the problem can you please help me?
Thanks in advance!
Best regards,
Abebe
May I ask how ?
Did you have the same problem that the code doesn't work when UI board is interfaced to the EVM ?
Thanks.
No, I do not have a problem wih intefacing the UI board. On the how: I used the fat file system from http://ultra-embedded.com/?fat_filelib. You only need to add the read and write function from the bsl and enable gcc extension and pack one of the structs in the fat_filelib.
Regards,
Abebe
Adebe,
Sorry I don't understand clearly what you mean.
Am I supposed to use write function from bsl code to example.c file media_write function ?
What do you man by gcc extension and packing one of the struct in the fat_filelib ?
Do I just need to use whole project downloaded from that link and copy only read and write function from BSL to example.c file ?
I will appreciate your help.
Thanks.
- Tariq
After you have downloaded the library write as follows:
1.Use the example code with this:
int media_init()
{
uint32_t rca;
MMCSD_init(MMCSD0);
MMCSD_identifyCard(MMCSD0, &rca, BUSWIDTH_4BIT);
return 1;
}
int media_read(unsigned long sector, unsigned char *buffer, unsigned long sector_count)
{
unsigned long i;
for (i=0;i<sector_count;i++)
{
MMCSD_readBlock(MMCSD0, sector, (uint32_t *)buffer);
sector ++;
buffer += 512;
}
return 1;
}
int media_write(unsigned long sector, unsigned char *buffer, unsigned long sector_count)
{
unsigned long i;
for (i=0;i<sector_count;i++)
{
MMCSD_writeBlock(MMCSD0, sector, (uint32_t *) buffer);
sector ++;
buffer += 512;
}
return 1;
}
This will use the driver from the bsl library.
2. in fat_defs.h give the struct the packed attribute. See below.
struct fat_dir_entry
{
uint8 Name[11];
uint8 Attr;
uint8 NTRes;
uint8 CrtTimeTenth;
uint8 CrtTime[2];
uint8 CrtDate[2];
uint8 LstAccDate[2];
uint16 FstClusHI;
uint8 WrtTime[2];
uint8 WrtDate[2];
uint16 FstClusLO;
unsigned int FileSize;
} __attribute__((packed));
3. Make sure he gcc extetion is activated.
Abebe,
I am getting attribute packed error even after copying your given code and enabling gcc extension from C6000 compiler - language option.
invalid attribute for "struct fat_dir_entry"
Any idea how to fix this ?
Adebe,
I am getting many warnings with or without using packed attribute.
Now I tried without packed attributes, program stopped with this error.
FAT_FS: Error could not load FAT details (-7)!
ERROR: Media attach failed
Tariq,
I believe that the (-7) has to do with the struct not being packed. Regarding the invalid attribute for the struct, I think that the problem can have to do with the compiler version. Which compiler are you using? Have a look at this thread: http://e2e.ti.com/support/embedded/starterware/f/790/t/171281.aspx.
/Abebe
Abebe,
My compiler version is 4.9.0 and CCS version is 4.2.0.
I also tried packing attributes the way explained in the following wiki page apart from what you mentioned but that didn't help either.
http://processors.wiki.ti.com/index.php/MSP430_-_Packing_Structure
What version of CCS and Compiler you using ?
-Tariq
Hi,
I'm using CCS version 5.2.0 and Code genration tool version 7.3.4.
/Abebe
Abebe,
Now I am using CCS v 5.1.0 and Code Generation Tool 7.3.4. I am not getting packed attributes error but this kind of error.

Is it possible for you to attach your working project ?
I appreciate your help,
Thanks.
Oh yeah, it has to do with some variables not being volatile. Try changing in the fat_misc.c file line 276
From:
entry->FstClusHI = FAT_HTONS((uint16)((startCluster>>16) & 0xFFFF));
entry->FstClusLO = FAT_HTONS((uint16)((startCluster>>0) & 0xFFFF));
To:
volatile unsigned int temp1 = (unsigned int)FAT_HTONS((uint16)((startCluster>>16) & 0xFFFF)); //Workaround bug
volatile unsigned int temp2 = (unsigned int)FAT_HTONS((uint16)((startCluster>>0) & 0xFFFF)); //Workaround bug
entry->FstClusHI = (uint16)temp1;
entry->FstClusLO = (uint16)temp2;
I hope it helps!
Abebe,
Thanks, that error has gone but now I am getting same error with -3 as given below. I tried with different SD card but no success.

You mind having look on my project ? OR provide me your working project so I see the difference.

I am getting error here,

Abebe,
I worked around that error but after executing this function, it keeps printing the message given below.
// List root directory
fl_listdirectory("/");

I let processor run for a long time but it never ended. Do you know what's wrong Or what am I supposed to do here ?
Thanks.
