|
The nuttx-0.3.15 release includes some new features:
|
||||||
Critical bugs fixed include:
|
|
||||||
<ul>
|
<ul>
|
||||||
<li>FAT FS:
|
<li>ROMFS
|
||||||
<ul>
|
<ul>
|
||||||
<li>Fixed several critical bugs with regard to fat reading and writing and FAT12
|
<li>
|
||||||
accesses. Basically the FAT FS only worked with my tiny test files and test
|
Adds support for the ROMFS filesystem
|
||||||
cases. A lot of stronger FAT tested is still needed!!</li>
|
</li>
|
||||||
<li>Fixed another FAT bug in implementation of FAT lseek; this prohibit correct
|
<li>R
|
||||||
random access to large files.</li>
|
ROMFS supports <code>mmap()</code> to provide eXecute In Place (XIP) capability
|
||||||
</ul>
|
</li>
|
||||||
</li>
|
<li>
|
||||||
<li>Network:
|
The NuttShell (NSH) can be configured to use ROMFS to provide a tiny read-only
|
||||||
|
filesystem with a startup script in <code>/etc</code>.
|
||||||
|
</li>
|
||||||
|
</ul></li>
|
||||||
|
<li>NXP LPC2148
|
||||||
<ul>
|
<ul>
|
||||||
<li>Corrected a critical bug that may prevent <code>recvfrom()</code> from receiving
|
<li>
|
||||||
packets from most remote UDP port numbers.</li>
|
The basic port of the NXP LPC2148 on the mcu123.com board was completed.
|
||||||
<li>Corrected an error in multi-threaded socket handling in <code>send()</code> and
|
That basic port includes successful booting, timer interrupts, serial console,
|
||||||
<code>sendto()</code>. Outgoing data could overwrite incoming data.</li>
|
succesfully passing the OS test, and a NuttShell (NSH) configuration.
|
||||||
<li>Corrected IP checksum calculation in ICMP and UDP message send logic.
|
</li>
|
||||||
<li>Corrected an error in <code>send()</code> timeout logic.</li>
|
</ul></li>

New features were also added:
|
|
||||||
<ul>
|
|
||||||
<li>Network:
|
|
||||||
<ul>
|
|
||||||
<li>Added support for application access to ICMP protocol stacks; Added
|
|
||||||
ping request logic (<code>net/uip</code>).
|
|
||||||
<li>Added basic TFTP client logic (<code>netutils/tftpc</code>).
|
|
||||||
</ul>
|
|
||||||
</li>
|
|
||||||
<li>NuttShell (NSH):
|
|
||||||
<ul>
|
|
||||||
<li>New commands: <code>test</code>, <code>[</code>, <code>ping</code>,
|
|
||||||
<code>mkrd,</code> <code>xd</code>, andTFTP <code>get</code> and <code>put</code> commands.

||||||
* FAT FS now uses position variable in struct file. This simplifies operations
|
* Added support for ROMFS filesystem.
|
||||||
like ftell().
|
* Added a simple test the ROMFS filesystem (examples/romfs)
|
||||||
* fseek() needs to discard bytes buffered by ungetc().
|
* NSH: Use ROMFS to provide an option for a start-up script at /etc/init.d/rcS
|
||||||
* Corrected ftell() return value.
|
* Add definition of BIOC_XIPBASE ioctl and implement in RAM disk block driver.
|
||||||
* Added fsetpos() and fgetpos().
|
This is a low level requirement for eXecute In Place (XIP) support.
|
||||||
* NSH: Now supports 'test' and '[' commands
|
* Add a FIOC_MMAP to perform memory mapping of a file and implemented the
|
||||||
* Correct error in send() timeout logic.
|
ioctl command in the ROMFS filesystem. This is a requirement for eXecute
|
||||||
* Correct error in multi-threaded socket handling in send() and sendto().
|
In Place (XIP) support.
|
||||||
Outgoing data could overwrite incoming data.
|
* Add mmap() API with restricted capability (only for XIP support)
|
||||||
* Add support to uIP for application access to ICMP protocol stacks; Add
|
* Extend ROMFS test at /examples/romfs to verify mmap() and XIP support.
|
||||||
ping request logic.
|
* Add support for Intel Hex format output using objcopy
|
||||||
* NSH: Add ping command
|
* Completed the basic port of the NXP LPC2148 on the mcu123.com board.
|
||||||
* Correct IP checksum calculation in ICMP and UDP message send logic.
|
The basic port includes successful booting, timer interrupts, serial console,
|
||||||
* NSH: Created an HTML document and a more detailed README file describing NSH.
|
succesfully passing the examples/ostest, and a NuttShell (NSH) configuration.
|
||||||
* Added basic TFTP client logic (netutils/tftpc). Untested as of initial check-in.
|
* ARM architectures now support drivers/lowconsole.c
|
||||||
* NSH: Add get and put commands to support TFTP get and put operations.
|
|
||||||
* NSH: Added a mkrd command that will create a RAMDISK that can be formatted
|
|
||||||
and mounted.
|
|
||||||
* Corrected a critical bug that prevent recvfrom from receiving packets from
|
|
||||||
any remote UDP port.
|
|
||||||
* NSH: Add hexadecimal dump command (xd)
|
|
||||||
