SkyEye-1.3.2_rc1 Released

Now we are glad to announce that Skyeye-1.3.2 is released after several monthes development. Comparing the last version.The big changes are:
* Add s3c6410 simulation by Du and unmodified linux of S3c6420 can run on SkyEye. We expect to run android in next release. The related documentation can be found at:
* Add unaligned memory access by YZheng. And now powerpc can use our common memory module.
* Add an independent 16550 uart module. You can add a uart for a virtual board by just adding one line on your config file.
* Add signal and address mapping API for supporting modular device better.
* Add a scheduler for faster IO simulation.
* Add a SOC directory and change almost all the arm machine module to the independent module.... read more

SkyEye-1.3.1 is released!

SkyEye-1.3.1 Release Notes

SkyEye-1.3.1 is released after eight months effort. Although we have done a lot of modifications, still have a lot of things that need to
be improved in our mind. In this release, both rpm package in binary format and source package are released.

The major improvement as the following:

* Support s3c2440 platform. Now we can run unmodified linux kernel on SkyEye.
* Support mpc8641d platform simulation. Now we can run unmodified linux
kenenl on SkyEye, but running application on mpc8641d have some issues.
* Fix the bug of return value in arm. Now we can run kernel module of linux on the SkyEye.
* Re-enable remote gdb debugger on the arm and powerpc platform. You should get the usage information from SkyEye user manual.
* Add net mode for uart output. That means you can redirect the output of
uart to some TCP/IP port.So you can get the uart output in another machine of the same network.
* add bus-log command so that you can record memory read/write activities.... read more

SkyEye-1.3.0_rc1 is released

SkyEye-1.3.0_rc1 based on SkyEye-1.2.9_rc1, has fixed most of the bugs in SkyEye-1.2.9_rc1. In this version , x86 simulation is added. The
following is the detail.

1. New features in SkyEye-1.3.0_rc1
1.1 Porting x86 simulation from Bochs project to SkyEye. Now most of
bochs testcases also can run on SkyEye.
1.2 Add ltdl as the wrapper of shared library. So we can generate dynamic module of SkyEye under non-linux platform.
1.3 Add a lot of fixes against build issues under MingW environment.
1.4 Add register mechinism for touchscreen buffer.Now the testcases
related to touchscreen can run.
1.5 Fix ths bus in flash simulation. Now the testcases related to Nor
flash can run. ... read more

skyeye-1.2.8_rc1 is released.......

skyeye-1.2.8_rc1 is released after several big improvements against skyeye-1.2.7_rc1.
New features is shown as the following:
1. Add mpc8572 support into skyeye. mpc8572 is dual core powerpc processor, and its linux BSP can run on SkyEye .You can find its testcase in out skyeye-testsuite-1.2.8 package.
2. Add sparc support into skyeye. Leon2 BSP of rtems can run with sparc simulation in skyeye-1.2.8
3. code coverage is improved. we fixed several bugs in code coverage ,and define a file format for profiling data file. You can refer to the file misc/code_cov/prof_convert.c
4. Add bfd library and libiberty library to third-party directory. So we can take use of them in any platform.... read more

skyeye-1.2.5 is released

Waiting for more than six months after last release , skyeye-1.2.5 is released.

Comparing to last version , the biggest change is we use autoconf/automake to build our source tree. So you need to use "./configure;make;make install" to build and install skyeye.

In addition to this, we also have the following improvement:
* Add code coverage profiling feature in SkyEye. You can find some example of code coverage usage from skyeye-testsuite-1.2.5 package.
* Fix several critical bugs in MIPS simulation, but MIPS simulation still not stable.
* Add DSI exception into PowerPC simulation, fix several bugs in instruction implementation. Now we can run UNMODIFIED linux with MPC8560 simulation
* Add load_addr option in skyeye.conf. Now we do not recommend to modify physical address of linux kernel source for running linux on SkyEye. You can use this option to relocated ELF image to any load address.
* cs8900a netcard simulation is improved. We can run ftp , telnet etc. based on it.
* DBCT function is disabled temporarily since autoconf can not detect gcc version. We will fix it later.... read more

skyeye-v0.8.8.5 Released

skyeye- released!
Now, skyeye can run on cygwin/windows and has a insight IDE environment.

great contribution from:

* base on version 0.8.7
* integrate insight with skyeye, many thanks to watercloud.
* port skyeye to cygwin.
1) temporary disable network simulation on win32.
2) lcd simulation on win32 need gtk support.There are many way to run gtk on win32.
we had test the following two methods.
a)using Xserver(XWin) which delivered with cygwin
b)using GTK binary release for cygwin on
* fix some bugs in makefile, let skyeye can compile in separate path
* Known bug: currently skyeye+insight on cygwin can not corrently deal with console input&output.
