Some problems with SD card on OMAP-L137

Jack Kilbey

Other Parts Discussed in Thread: OMAP-L137, DA8XX

Dear All,

We have three OMAP-L137 boards. We have developed a application executed on ARM that reads data from audio interface and sends it to the DSP, then receives the processed data and play it. When we mount the file system by NFS on PC all things are good. HOWEVER, when we copy the file system to SD card to have a standalone system and mount file system on SD card all things go wrong. The following errors happen when I run the application:

error -110 sending read/write command

end_request: I/O error, dev mmcblk0, sector 15277817

Buffer I/O error on device mmcblk0p2, logical block 1894367

Remounting file system as read only

We formatted the SD card but it did not solve the problem.

Thanks,

Jack

Hi Jack,

I presume that you are facing problem while mounting fs on SD card,

Use the following boot command in u-boot,

setenv bootargs console=ttyS2,115200n8 noinitrd rw ip=dhcp root=/dev/mmcblk0p1 rootfstype=ext2 mem=32M

http://processors.wiki.ti.com/index.php/GSG:_Building_Software_Components_for_OMAP-L1/AM1x#MMC.2FSD

http://processors.wiki.ti.com/index.php/Alternate_Boot_Methods_for_OMAP-L137/DA830#From_SD.2FMMC

Possibilities of "-110" error. (timeout)

SD card got broken, not inserted properly, voltage problem from hw, etc.,

Have you tried the same SD card on your PC?

Are you using linux on OMAPL137 devices?

If yes, follow the commands to copy file from arm fs to SD card.

mount -t /dev/mmcbl0p1 /mnt

mount (to check whether mounted)

cp -rf /test_file.txt /mnt

sync

umount /mnt

Dear Sir,

1. I presume that you are facing problem while mounting fs on SD card, Use the following boot command in u-boot,

setenv bootargs console=ttyS2,115200n8 noinitrd rw ip=dhcp root=/dev/mmcblk0p1 rootfstype=ext2 mem=32M

http://processors.wiki.ti.com/index.php/GSG:_Building_Software_Components_for_OMAP-L1/AM1x#MMC.2FSD

http://processors.wiki.ti.com/index.php/Alternate_Boot_Methods_for_OMAP-L137/DA830#From_SD.2FMMC

I have already done the above-mentioned works. The file system is mounted correctly when the Linux kernel is booted. When I run the program, after a while the errors happens.

Possibilities of "-110" error. (timeout)

SD card got broken, not inserted properly, voltage problem from hw, etc.,

Have you tried the same SD card on your PC?

Yes, I tried the SD card on my PC. Moreover, I used some another SD cards to check this possibility.

Are you using linux on OMAPL137 devices?

Yes, I am using linux on OMAP-L137.

If yes, follow the commands to copy file from arm fs to SD card.

mount -t /dev/mmcbl0p1 /mnt

mount (to check whether mounted)

cp -rf /test_file.txt /mnt

sync

umount /mnt

When the error occurs the system halts.

I think it may be due to a synchronization issue. This problem make us anxious seriously. It does not seem reasonable. They should check this issue.

Jack,

Hi,

When I run the program, after a while the errors happens.

You are facing the problem when you run your ARM app, Right!

Can you please follow the procedure to check the problem before running the ARM app.

mount (to check whether mounted already thr AUTOMOUNT)

mount -t extX /dev/mmcbl0p1 /mnt

mount (to check whether mounted)

cp -rf /test_file.txt /mnt

sync

umount /mnt

Could you please share your complete bootup logs(with running commands) of both working and non-working (mount fs on SD & NFS)

Dear Sir,

I run the commands you have been mentioned. The errors still occur.

Hi,

In future, Please attach your bootup logs and not simple text paste.

Is the DSP code from TI or own code which you are running thr syslink?

If any TI example projects used, provide the package & version details.

If own, Do you have any SD/MMC support/stuffs in your DSP code?

What are you trying to do with your DSP code?

I suspect that your DSP code doing some init on SD/MMC,

1) Boot your board with NFS,

2) Try to access the contents of your SD card like copying the files from SD card to filesystem, deleting the contents from SD card in back ground job(copying or deleting the file size should be big)

3) Now runt the DSP code.

Ex:

1) Booted the board with NFS

target # mount -t ext3 /dev/mmcbl0p2 /mnt

target #cp -rf /test_file.mp4 /mnt & ("&" symbol will do the job in background)

test_file.mp4 size is around 50MB

3) Run the DSP code

toot@(none):/opt/DSPLinkExample/HF_Simulator# ./HF_Simulator_GPP HF_Simulator.out

Please provide the results.

I found the problem. In DSP, we used LED. To work with LEDs you should initiate i2c. I think a conflict was happened. When I remove the code all things were good..

Thanks,

Jack
