Re: eCos for Renesas EDOSK-2674


Hello Jonathan,

thank you for your reply.

Status of EDOSK-2674 port.

Last week the port passed the eCos test suite. A protocol of all executed
tests is available on my homepage
http://www.htwm.de/ukindler/ecos or directly here
http://www.htwm.de/~ukindler/ecos/ecos_test_protocol.htm
The tests (execept the dhrystone, tm_basic and serial tests) where executed
with assertions enabled. No alignment errors, stack violations or any other
assertion failures occured. So the port seems to be quite stable now and the
patched toolchain seems to work well.

The documentation is not finished and the ethernet drivers are not tested
(eCos tests for ethernet drivers have not been executed) but console output
and debugging over TCP/IP with RedBoot works fine so the driver seems to be
o.k.

In order to use the port the toolchain from my homepage is required. The
latest patches from Yoshinori Sato and from me have been applied in order to
enable building of math library. I created an additional patch wich
introduces a new compiler switch -mecos. This switch forces an alignment of
all one- and multidimensional arrays with an alignment < 4 byte to a 4 byte
boundary. This is required in order to avoid problems with char arrays used
as thread stacks (like the idle thread stack).

I sent the signed copyright assignment to eCosCentric today.

Best Regards,
