|
||||
of an RS-232 serial console. However, that configuration has not
|
||||
been impelmented as of this writing.
|
||||
|
||||
4. This configuration includes USB Support (CDC/ACM device)
|
||||
4. Memory Usage. The size command gives us the static memory usage.
|
||||
This is what I get:
|
||||
|
||||
CONFIG_STM32_USB=y : STM32 USB device support
|
||||
CONFIG_USBDEV=y : USB device support must be enabled
|
||||
CONFIG_CDCACM=y : The CDC/ACM driver must be built
|
||||
CONFIG_NSH_BUILTIN_APPS=y : NSH built-in application support must be enabled
|
||||
CONFIG_NSH_ARCHINIT=y : To perform USB initialization

||||
$ size nuttx

||||
text data bss dec hex filename
|
||||
35037 106 1092 36235 8d8b nuttx
|
||||
|
||||
The CDC/ACM example is included as two NSH "built-in" commands.
|
||||
And we can get the runtime memory usage from the NSH free command:
|
||||
|
||||
CONFIG_EXAMPLES_CDCACM=y : Enable apps/examples/cdcacm
|
||||
NuttShell (NSH) NuttX-6.25

||||

|
||||
Mem: 14160 3944 10216 10216
|
||||
nsh>
|
||||
|
||||
The two commands are:
|
||||
Summary:
|
||||
|
||||
sercon : Connect the serial device a create /dev/ttyACM0
|
||||
serdis : Disconnect the serial device.
|
||||
- This slightly tuned NSH example uses 34.2KB of FLASH leaving 93.8KB
|
||||
of FLASH (72%) free from additional application development.
|
||||
|
||||
NOTE: The serial connections/disconnections do not work as advertised.
|
||||
This is because the NuTiny-SDK-NUC120 board does not provide circuitry for
|
||||
control of the "soft connect" USB pullup. As a result, the host PC
|
||||
does not know the USB has been logically connected or disconnected. You
|
||||
have to follow these steps to use USB:
|
||||
I did not do all of the arithmetic, but it appears to me that of this
|
||||
34+KB of FLASH usage, probably 20-30% of the FLASH is used by libgcc!
|
||||
libgcc has gotten very fat!
|
||||
|
||||
1) Start NSH with USB disconnected
|
||||
2) enter to 'sercon' command to start the CDC/ACM device, then
|
||||
3) Connect the USB device to the host.
|
||||
- Static SRAM usage is about 1.2KB (<4%).
|
||||
|
||||
and to close the connection:
|
||||
- At run time, 10.0KB of SRAM (62%) is still available for additional
|
||||
applications. Most of the memory used at runtime is allocated I/O
|
||||
buffers and the stack for the NSH main thread (1.5KB).
|
||||
|
||||
4) Disconnect the USB device from the host
|
||||
5) Enter the 'serdis' command
|
||||
There is probably enough free memroy to support 3 or 4 application
|
||||
threads in addition to NSH.
