Re: Mounting/Accessing SD-Card on BBB

2019-08-15 Thread Christian Mauderer

Hello Nils,

does some other access to the file system work? Like a ls on the console
or creating a file. Can you do a `cat` on some text file on the file
system? If not: Does it work for a file in the root file system (should
be a IMFS)?

Best regards

Christian

Hi,

I when my app wants to open a file on the SD card dev=mmcsd-0-0 rtems
freezes.
Exact call is:
fd = open(file, O_RDONLY);
With file being the pru binary I want to upload.

Thanks,
Nils

Hi,

I was able to mount the sd card.
It was FAT, that was missing.

Thanks,

Hi,

Thanks for the input I will try the SD card first.
That way I won't have to alter the code when I want to run other stuff on

2019-08-13 Thread Christian Mauderer

Hello Nils,

that's a bit odd. I attached an expected output below. Some guesses:

- Did you add FAT file system to your application?
- Is there some odd formatting on the SD? Normally at least the FAT
partition used by U-Boot should be visible.
- Is your BDBUF configuration OK?
- Do you have enough file descriptors?

Beneath that: If you only need something where you can put some files,
you can try to connect a USB stick instead. Maybe that works better.

Best regards

Christian

Hi,

Thanks for the help.
I tried to use your code, but I always get "ERROR: SD could not be mounted

Even after raising the waiting time.

Hello Nils,

take a look at the following application:

https://gitlab.com/c-mauderer/rtems-bbb/blob/master/apps/wifi-sample/init.c#L64

https://gitlab.com/c-mauderer/rtems-bbb/blob/master/apps/wifi-sample/libbsdhelper.c#L122

You should mainly need the stuff from the libbsdhelper_init_sd_card()
and libbsdhelper_wait_for_sd().

Please note that the SD card needs quite some time to initialize on BBB.
I haven't had a look at it why that is the case.

Best regards

I need to access the BBB's SD-Card, so that I can load my pru example on
