The standard FreeBSD MII support causes severe problems on the LPC3200
chip family. If an Ethernet module register is accessed while there is
no clock from the PHY, the chip completely locks up and only an external
watchdog can recover from this state. The legacy driver had a custom
PHY management code which helped to avoid such issues. The if_lpe.c
driver is no longer maintained by FreeBSD.
How test media01 can be executed is described in section
*Qemu and Networking* of the README.md at the top of the
rtems-libbsd GIT repository.
When connected via `telnet` with the RTEMS shell of the
media01.exe test executed by QEMU, one can list the filesystems
available for mounting:
TLNT [/] # mount -L
File systems: / dosfs tftpfs
The list will contain `tftpfs`. The filesystem can be mounted
as in the following example:
TLNT [/] # mkdir /tftp
TLNT [/] # mount -t tftpfs -o verbose "" /tftp
A TFTP server is needed to use this filesystem. The simplest way
would be to run such a server on the host machine and open the
firewall for the TFTP protocol (port 69) on the TAP device used.
Files can then be downloaded using the usual shell commands
as in the following example:
TLNT [/] # cat /tftp/169.254.1.1:hello.txt
Uploading is also possible provided the TFTP server supports it,
for example:
TLNT [/] # cp /etc/dhcpcd.duid /tftp/169.254.1.1:myfile
Added a new test for the TTCP command. Modified default-network-init.h
to conditionally build the shell with TTCP. Modified libbsd.py to build
the new TTCP test.
Updated ttcp.c to build clean for RTEMS 6 and the machines it
originally built for. Also fixed ttcp.c to close network
sockets after completion. Defined a shell command for TTCP in
rtems-bsd-shell-ttcp.c. Added TTCP to the list of RTEMS network
commands in netcmds-config.h. Added declaration of the TTCP shell
command to rtems-bsd-commands.h. Modified libbsd.py to make waf
build TTCP and its shell command.
Add a System Level Control Register driver for the Xilinx Zynq
Ultrascale+ MPSoC with basic clock control functionality for use with
the Cadence GEM. This also removes the Zynq-7000 clock control weakref
from compilation depending on the BSP in use.
- Do not build a test if a dependency is not enabled.
- Perform a dependency check and generate an error if an enabled module
depends on a disabled module.
Closes#4077
- Provide support for separate user and kernel include paths in
libbsd.py.
- Update all added files with a suitable context to build them
with. Supported contexts are `kernel` and `user`.
- Kernel source use the kernel, CPU, and build header paths in
this order.
- User source use the user, kernel, CPU and build header paths
in this order. The FreeBSD /usr/include tree has some kernel
header files installed as well as user land header files. This
complicates the separation as some kernel header files are not
visible to user land code while other are. This is handled by
appending the kernel header paths to the user header paths so
user land code will include a user header with the same name as
a kernel header over the kernel header but will find a kernel
header if there is no matching user header file.
Closes#4067
There is a bug in the #ifdef regarding FDT so this file hasn't been
compiled. If that bug is solved, the driver doesn't work for some other
reason.
With the FDT-bug the driver hasn't been used by anyone. So just remove
it again.
- Update FreeBSD files in libbsd.py to required by i386 based BSPs
- Some machine specific header files have moved to different directories
in FreeBSD
- Add missing files e1000 network driver (iflib*)
- path-mappings allow to fix autogenerated include paths for some corner
cases of target platforms without the need to change the build system
- Currently used for i386 based bsps
