Subject: [U-Boot] SD card on the GuruPlug
Date: Fri, 01 Oct 2010 18:17:44 +0200 [thread overview]
Message-ID: <87ocbd7uqf.fsf@gnu.org> (raw)
Hello,
The GuruPlug has an internal ?SD card reader, which it views as a USB
device:
--8<---------------cut here---------------start------------->8---
Marvell>> usb start
(Re)start USB...
USB: Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 3 USB Device(s) found
scanning bus for storage devices... Device NOT ready
Request Sense returned 02 3A 00
1 Storage Device(s) found
Marvell>> usb tree
Device Tree:
1 Hub (480 Mb/s, 0mA)
| u-boot EHCI Host Controller
|
+-2 Hub (480 Mb/s, 100mA)
| USB2.0 Hub
|
+-3 Mass Storage (480 Mb/s, 500mA)
USB Storage 000000009909
--8<---------------cut here---------------end--------------->8---
However, with a ?SD card in, with a valid MS-DOS partition table, it
apparently fails to read from it:
--8<---------------cut here---------------start------------->8---
Marvell>> usb part
## Unknown partition table
--8<---------------cut here---------------end--------------->8---
Conversely, ?usb part? works as expected with a USB key or USB disk
plugged in.
Does anyone have experience with it? Any idea how I could further debug
the problem?
Thanks,
Ludo?.
