Dear All and Scott
I compile and bulid "hello ecos world" and invoke or1ksim and ddd with
or32-elf-gdb
show the machine code window :
Dump of assembler code for function main:
0xf00012a4 : l.addi r1,r1,0xfffffffc
0xf00012a8 : l.sw 0x0(r1),r2
0xf00012ac : l.addi r2,r1,0x4
0xf00012b0 : l.addi r11,r0,0x0
0xf00012b4 : l.lwz r2,0x0(r1)
0xf00012b8 : l.jr r9
0xf00012bc : l.addi r1,r1,0x4
End of assembler dump.
and then issue the command "target jtag jtag://localhost:9999
(gdb) target jtag jtag://localhost:9999
Remote or1k debugging using jtag://localhost:9999
0x00000104 in ?? ()
~~~ not main ?? why
(gdb)
the machine code window becomes :
Dump of assembler code from 0x104 to 0x204:
0x104: l.j 0x0
0x108: l.j 0x0
0x10c: l.j 0x0
0x110: l.j 0x0
0x114: l.j 0x0
0x118: l.j 0x0
0x11c: l.j 0x0
0x120: l.j 0x0
0x124: l.j 0x0
0x128: l.j 0x0
0x12c: l.j 0x0
0x130: l.j 0x0
0x134: l.j 0x0
0x138: l.j 0x0
why and how should I do ?

Hey!
if you compile ecos to run from ROM, then enable mc in simulator and
it should work. if you want to simulate runing it from ram, you'd have
to recompile ecos with (i think) CYG_HAL_STARTUP RAM, and then just turn
mc off in the simulator.
best regards,
