SUN OBP source code released
by Jose Renau
Hi all,
SUN has released (under BSD license I believe), the source
code for their OpenBoot (OPB). This includes the forth programs
for many of their sun machines.
This is available only starting from version 1.3 of OpenSPARC.
http://opensparc-t1.sunsource.net/download_hw.html
I guess that it could be a good boost on the functionality/code
available at OpenBios.

esp large sector handling
by Paul Brook
The current esp code will perform partial reads on devices with sector sizes >
512. The attached patch makes it read the whole sector from the device, and
uses the additional if multiple blocks are requested.
I'm not sure if the old behavior is technically wrong, but it confused me when
debugging the qemu device emulation :-)

BOOTSTRAP and libc
by Rolf Schroedter
Could somebody please enlighten me what is the idea of libc/*.c files ?
What does it mean that if -DBOOTSTRAP uses the standard C-library,
and -UBOOTSTRAP uses the openbios-libc ?
I'm asking, because I want to embed a minimal FCode interpreter into a
C-application,
which of course itself uses the standard C-library.
Thanks & regards,
Rolf.

FCode on an embedded Leon-Sparc system
by Rolf Schroedter
For a scientific space project I'm thinking about including an FCode
interpreter into the onboard software.
The target system is a Leon3 processor (Sparc-V8) in FPGA with serial
port(s), spacewire and a few other interfaces.
I'm able to compile & run bare C applications (gcc cross-compiler), so
it seems to me that I don't need a real BIOS.
Having some experience with Forth I would like to include a FORTH
interpreter for
- interactive hardware implementation & testing via the serial port
- executing FORTH code (precompiled bytecode ?) via telecommands during
flight.
Ideally the complete FORTH system should be in the range of 32-40 kBytes...
I'm completely new to OpenBios & FCode. Any suggestions are appreciated:
- where to start
- how to strip down the OpenBios code
- etc.
Thanks & regards,
Rolf.

Enable Sparc32 power management
by Blue Swirl
Hi,
Aurelien Jarno fixed Sparc32 power management I/O in Qemu, so Sparc32
emulator does not make constant 100% CPU load anymore.
This patch enables the chip from OpenBIOS, please apply.

Re: [OpenBIOS] Fixes for 'int' use

>any reason for removing all consts in forth.c?
Sorry, I had the confused idea of considering these as errors. Now I know
better... The attached patch contains the good pieces of the previous patch.
