-Introduction
----------------------
-This README file provides guideliness to compile successfully the
-Etherboot for Hyperstone.
-This directory (src/arch/e1) contains the files that depend on
-Hyperstone's architecture. The header files that include the
-configuration of the system are based on Hyperstone's E132-XS
-development board. The can be very easily modified to support
-anyother configuration environment.
-
-Software Perquisites:
----------------------
-The build environment requires a C compiler for the E1-32XS
-processor. Normally you can simply install a cross-compiling tool
-chain based on the GNU tools (that is binutils and gcc). If you
-are running a Linux system on a x86 CPU then you can just download
-the toolchain as a binary from Hyperstone's official web-site. The
-binary distribution will untar the tools in the /usr/local/e1-coff
-directory. On any other system you will need to build the tool
-chain from the sources.
-
-To compile successfully the following tools should be available:
- - GNU toolchain:
- - GCC ver 2.95.2 20030110 (release) e1-coff-gcc -v
- - LD ver 2.12.90 20020726 e1-coff-ld -V
-
-Hardware Perquisites:
----------------------
-The etherboot has been successfully tested in the E1-32XS
-development board. A second serial device is initialized
-to act as a console. The standard messages
-are redirected to the console. Nevertheless, if one wants not
-to use the serial console he may omit the corresponding switches
-from the Config file located under "src/arch/e1/" directory.
-
-On the E1-32XS board that was used, a daughter-board was employed
-to connect a second HyIce to the development board. Since the HyIce
-embeds a standard 16550 device, the Etherboot's standard device
-driver is used.
-
-The position of the jumpers of the development board in order to
-initialize both the second HyIce and the Ethernet device is
-depicted in the following table:
-
-Jumper: Position
-------:--------------
-J3 1-2 (default)
-J4 1-2 (default)
-J13 5-6
-J5 1-2 (default)
-J6 1-2 & 3-4
-J7 3-4
-J9 1-2 (default)
-J10 1-2
-J11 3-4
-
-Compilation
----------------------
-In order to compile Etherboot for Hyperstone, the following steps should be followed:
-1) Edit the main Makefile (located under "src" directory") and comment-out
-the ARCH variable (by putting a "#" in front of it). Append the following line:
-ARCH:=e1
-2) Edit the Config file (the one located under "src" directory) and make sure that
-the CFLAGS variable will contain *only* the following swithces:
-CFLAGS+= -DCONFIG_ISA
-CFLAGS+= -DBOOT_FIRST=BOOT_NIC
-CFLAGS+= -DALLOW_ONLY_ENCAPSULATED
-CFLAGS+= -DBACKOFF_LIMIT=7 -DCONGESTED
-CFLAGS+= -DCOFF_IMAGE
-CFLAGS+= -DDOWNLOAD_PROTO_TFTP
-Please note that extra or any other switches may cause failure of compilation!
-3) type "make hyperstone" or "make coff"
-4) the generated file will be located under the "src/bin" directory and will be called :
- "etherboot.coff". Now you may download it with usual way using e1-coff-gdb ..
