First modify the Makefile to use the compiler installed on your + machine. Then issue the command: + + $ make + + This should produce the default target sh2-7045edk.out. This is the + S-record file which should be added to FDT project (renaming it to + *.mot extension helps a bit). + If you are lucky you will be able to put the file into the FLASH + following the instuctions in FDT and EVB manuals. + + Well I wasn't lucky so I had to bypass the Universal Programming + Board (see EVB7045F User Manual) and manually put the processor into + BOOT mode. This can be done by shortening the capacitor C8 (or C108 + on schematics) which puts the UPB into permanent reset state, and by + removing jumper JP4 (or JP104 on schematics) and connecting its + middle pin to the ground. After pressing CRES button the processor + is in BOOT mode. In FDT select "direct connection": + + Menu Project->Properties->Device->Select Interface + + After that there should be no problem in putting the program into the + FLASH. + + Loading 'hello.exe' on board +------------------------------ + I assume you are able to compile RTEMS with 'gensh2' BSP and + necessary tools. If not please refer to 'started.pdf' document which + describes the procedure (http://www.oarcorp.com/). + + At the time of writing this document 'gdbstubs' default + communication port was SCI1. So it was the default port for + /dev/console in RTEMS. To avoid problems I had check these settings + both in 'gdbstubs' and $RTEMS_ROOT/c/src/lib/libbsp/sh/gensh2/include/bsp.h + + After changing the line + + #define BSP_CONSOLE_DEVNAME "/dev/sci1" + + to + + #define BSP_CONSOLE_DEVNAME "/dev/sci0" + + in 'bsp.h' and rebuilding RTEMS there should no problem in running + 'hello.exe' and other samples. + + For downloading connect a serial cable to computer and EVB. You will + also need a second cable and second serial port to see the effects + of your work. + + Assuming you are working in Linux and Xwindows fire up two terminal + windows. In the first one run sh-rtems-gdb, in the second run a + serial port terminal (for example 'minicom'). Set up the serial + terminal to a port connected to SCI0 and leave the window in a + visible place on the desktop. The debugger should be invoked best + from the directory where 'hello.exe' is placed.
