Hi, when i'm trying to start compilation, i get this message:
Error (10528): VHDL error at spwstream.vhd(294): value "0" is outside the target constraint range (1 to 255)
Error (10346): VHDL error at spwstream.vhd(292): formal port or parameter "disconnect_time" must have actual or default value

292    recv_inst: spwrecv
293        generic map(
294            disconnect_time => disconnect_time,
295            rxchunk     => rxchunk )

What i'm doing wrong?

disconnect_time

Dear Joris,

 I'm having some problems to compile your spwltest.c software. The problem is that the compile does not find some structures/functions that you use on your code:

Compile Error:
------
nsee@nsee-1:~/NSEE/SpW/spacewire_light/trunk/sw/rtems_driver$ make
sparc-rtems-gcc -B/opt/rtems-4.10/sparc-rtems/leon3/lib/ -specs bsp_specs -qrtems -msoft-float -Wall -Os -c spwltest.c
spwltest.c:216: error: 'amba_apb_device' undeclared (first use in this function)
spwltest.c:216: error: (Each undeclared identifier is reported only once
spwltest.c:216: error: for each function it appears in.)
spwltest.c:216: error: expected ';' before 'apbdev'

spwltest.c:225: error: 'amba_conf' undeclared (first use in this function)
spwltest.c:225: error: 'apbdev' undeclared (first use in this function)

I've tried to find it on the rtems includes but they do not exist:
-----
nsee@nsee-1:/opt/rtems-4.10$ find . -type f -exec grep -i "amba_confamba_conf" {} \; -print
nsee@nsee-1: 

Compile version

nsee@nsee-1:~/NSEE/SpW/spacewire_light/trunk/sw/rtems_driver$ sparc-rtems-gcc --version

Thanks in advance,

rtems spwltest

Thanks for the reply, but in the library GRLIB, too, there is no file "syncram_2p.vhd!!!

NO FILE

The package "spwamba.vhd" no file "syncram_2p.vhd"!!!

On the spwlink.vhd, line 111: when r.state = S_ErrorWait , you test the fallowing errors:

 ESCAPE ERROR, PARITY ERROR AND CHARACTER SEQUENCE ERROR,

 but by the standard (ECSS-E-50-12A - 8.5.3.9.3b and 8.5.3.9.4b and 8.5.3.11b) it's says that this errors must be    checked only  after the first NULL had been received. And it's not the case. The same error repeat for r.state = S_Ready .

 Thank you,
