Linux

Reciva provides sources for the Linux kernel used on the Barracuda on the GPL archive page. First inspection of these sources show the following:

• A UART should be available somewhere on the hardware and a console is enabled

• LIRC (linux remote control) might be available

• more to discover here of course

Building

The following worked for me:

Creating the toolchain

It seems that reciva uses glibc 2.3.2 and gcc 3.3.4 at this moment. We'll create a toolchain with the same versions:

• make sure you are not logged in as root
• download and unpack crosstool
• eval `cat arm.dat gcc-3.3.4-glibc-2.3.2.dat` sh all.sh --notest
• In case of PATH_MAX undeclared error, copy the patch from the gcc-3.3.6 directory with

 cp  patches/gcc-3.3.6/fix-fixincl.patch patches/gcc-3.3.4/  

• and run the eval again.
• Have some coffee beer

Compiling the linux kernel

• Download linux sources from Reciva and unpack
• make bast_config
• make menuconfig - exact configuration to be determined
• Edit the top-level makefile in the bast_linux directory and point CROSS_COMPILER to the freshly built toolchain
• The same as above in the recive/Makefile
• make
• make
• make modules
• make -C reciva
