config SYSTEM_USBMSC
bool "USB mass storage class controls"
default n
depends on USBMSC && !KERNEL_BUILD
---help---
Enable the USB mass storage class controls. These controls include:
msconn: Connect the mass storage device to the host
msdis : Disconnect the mass storage device to the host
if SYSTEM_USBMSC
config SYSTEM_USBMSC_NLUNS
int "Number of LUNs"
default 1
---help---
Defines the number of logical units (LUNs) exported by the USB
storage driver. Each LUN corresponds to one exported block driver
(or partition of a block driver). May be 1, 2, or 3. Default is 1.
config SYSTEM_USBMSC_DEVMINOR1
int "LUN1 Minor Device Number"
default 0
---help---
The minor device number of the block driver for the first LUN. For
example, N in /dev/mmcsdN. Used for registering the block driver.
Default is zero.
config SYSTEM_USBMSC_DEVPATH1
string "LUN1 Device Path"
default "/dev/mmcsd0"
---help---
The full path to the registered block driver. Default is
"/dev/mmcsd0"
config SYSTEM_USBMSC_DEVMINOR2
int "LUN2 Minor Device Number"
default 1
---help---
The minor device number of the block driver for the second LUN. For
example, N in /dev/mmcsdN. Used for registering the block driver.
Ignored if SYSTEM_USBMSC_NLUNS < 2. Default is one.
config SYSTEM_USBMSC_DEVPATH2
string "LUN2 Device Path"
default "/dev/mmcsd1"
---help---
The full path to the registered block driver. Ignored if
SYSTEM_USBMSC_NLUNS < 2. Default is "/dev/mmcsd1"
config SYSTEM_USBMSC_DEVMINOR3
int "LUN3 Minor Device Number"
default 2
---help---
The minor device number of the block driver for the third LUN. For
example, N in /dev/mmcsdN. Used for registering the block driver.
Ignored if SYSTEM_USBMSC_NLUNS < 2. Default is two.
config SYSTEM_USBMSC_DEVPATH3
string "LUN3 Device Path"
default "/dev/mmcsd2"
---help---
The full path to the registered block driver. Ignored if
SYSTEM_USBMSC_NLUNS < 2. Default is "/dev/mmcsd2"
config SYSTEM_USBMSC_DEBUGMM
bool "USB MSC MM Debug"
default n
---help---
Enables some debug tests to check for memory usage and memory leaks.
config SYSTEM_USBMSC_TRACE
bool "Trace USB activity"
default n
depends on (USBDEV_TRACE || DEBUG_USB) && !NSH_BUILTIN_APPS
---help---
If this add-on is built as a standalone task and if USB device tracing is
enabled, then this add-on can be configured to unobtrusively monitor
USB activity by selecting this option.
if SYSTEM_USBMSC_TRACE
config SYSTEM_USBMSC_TRACEINIT
bool "USB Trace Initialization"
default n
---help---
If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
then the add-on code will also manage the USB trace output. The
amount of trace output can be controlled this configuration value:
This setting will show USB initialization events
config SYSTEM_USBMSC_TRACECLASS
bool "USB Trace Class"
default n
---help---
If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
then the add-on code will also manage the USB trace output. The
amount of trace output can be controlled this configuration value:
This setting will show USB class driver events
config SYSTEM_USBMSC_TRACETRANSFERS
bool "USB Trace Transfers"
default n
---help---
If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
then the add-on code will also manage the USB trace output. The
amount of trace output can be controlled this configuration value:
This setting will show USB data transfer events
config SYSTEM_USBMSC_TRACECONTROLLER
bool "USB Trace Device Controller Events"
default n
---help---
If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
then the add-on code will also manage the USB trace output. The
amount of trace output can be controlled this configuration value:
This setting will show USB device controller events
config SYSTEM_USBMSC_TRACEINTERRUPTS
bool "USB Trace Device Controller Interrupt Events"
default n
---help---
If USBDEV_TRACE is enabled (or DEBUG and DEBUG_USB),
then the add-on code will also manage the USB trace output. The
amount of trace output can be controlled this configuration value:
This setting will show USB device controller interrupt-related events.
endif # SYSTEM_USBMSC_TRACE
if NSH_BUILTIN_APPS
config SYSTEM_USBMSC_CMD_STACKSIZE
int "Stacksize of msconn and msdis commands"
default 768
---help---
Size of the stack used by the small 'msconn' and 'msdis' command
applications. Warning, just because the applications are small,
the stack usage could still be deep!
config SYSTEM_USBMSC_CMD_PRIORITY
int "Priority of the msconn and msdis commands"
default 100
---help---
Priority of the small 'msconn' and 'msdis' command applications.
config SYSTEM_USBMSC_DAEMON_STACKSIZE
int "Stacksize of msconn daemon"
default 2048
---help---
To avoid threading entanglements, the USB MSC class is initialized
on a daemon thread. This permits the msconn application to return
to the NSH command line immediately. This is the stack used for
that short-lived USB MSC initialization daemon.
config SYSTEM_USBMSC_DAEMON_PRIORITY
int "Priority of the msconn daemon"
default 100
---help---
To avoid threading entanglements, the USB MSC class is initialized
on a daemon thread. This permits the msconn application to return
to the NSH command line immediately. This is the priority used for
that short-lived USB MSC initialization daemon.
