Hi, Thanks for the help. I tried to use your code, but I always get "ERROR: SD could not be mounted after timeout". Even after raising the waiting time.
The sources I use start here: https://github.com/nilhoel1/rtems-pru/blob/pruss-shell/main.c#L110 And my uart output is: "" waiting for SD... usbus0: 480Mbps High Speed USB v2.0 usbus1: 480Mbps High Speed USB v2.0 media listener: event = DISK ATTACH, state = INQUIRY, src = mmcsd media listener: event = DISK ATTACH, state = SUCCESS, src = mmcsd, dest = /dev/mmcsd-0 media listener: event = MOUNT, state = INQUIRY, src = /dev/mmcsd-0 ugen0.1: <Mentor Graphics OTG Root HUB> at usbus0 ugen1.1: <Mentor Graphics OTG Root HUB> at usbus1 uhub0: <Mentor Graphics OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0 uhub1: <Mentor Graphics OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus1 media listener: event = MOUNT, state = FAILED, src = /dev/mmcsd-0 media listener: event = PARTITION INQUIRY, state = INQUIRY, src = /dev/mmcsd-0 media listener: event = PARTITION INQUIRY, state = SUCCESS, src = /dev/mmcsd-0 media listener: event = PARTITION ATTACH, state = INQUIRY, src = /dev/mmcsd-0 media listener: event = PARTITION ATTACH, state = SUCCESS, src = /dev/mmcsd-0, dest = /dev/mmcsd-0-0 media listener: event = MOUNT, state = INQUIRY, src = /dev/mmcsd-0-0 media listener: event = MOUNT, state = FAILED, src = /dev/mmcsd-0-0 media listener: event = DISK ATTACH, state = INQUIRY, src = mmcsd media listener: event = DISK ATTACH, state = SUCCESS, src = mmcsd, dest = /dev/mmcsd-1 media listener: event = MOUNT, state = INQUIRY, src = /dev/mmcsd-1 media listener: event = MOUNT, state = FAILED, src = /dev/mmcsd-1 media listener: event = PARTITION INQUIRY, state = INQUIRY, src = /dev/mmcsd-1 media listener: event = PARTITION INQUIRY, state = SUCCESS, src = /dev/mmcsd-1 media listener: event = PARTITION ATTACH, state = INQUIRY, src = /dev/mmcsd-1 media listener: event = PARTITION ATTACH, state = SUCCESS, src = /dev/mmcsd-1, dest = /dev/mmcsd-1-0 media listener: event = MOUNT, state = INQUIRY, src = /dev/mmcsd-1-0 media listener: event = MOUNT, state = FAILED, src = /dev/mmcsd-1-0 media listener: event = DISK ATTACH, state = INQUIRY, src = mmcsd1boot uhub0: 1 port with 1 removable, self powered uhub1: 1 port with 1 removable, self powered ERROR: SD could not be mounted after timeout "" Thanks, Nils On Mon, 12 Aug 2019 at 18:01, Christian Mauderer <l...@c-mauderer.de> wrote: > On 12/08/2019 07:28, Nils Hölscher wrote: > > Hi, > > > > Can anyone help me with this? > > I need to access the BBB's SD-Card, so that I can load my pru example on > > the pru. > > > > Thanks, > > Nils > > > > 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 > > Christian >
