I wanted to compile to or1k but I don't want to use any OS ucLinux or RTEMS. Thanks! Learner __________________________________ Do you Yahoo!? Yahoo!

'or32-uclibc-gcc' is for building applications which will run on ucLinux. 'or32-uclinux-gcc' is for building ucLinux itself and the simulator. If you want to build vanilla targets with no OS dependencies I would recommend building the tools with the target as 'or32-elf'. The 'Build the OR1K tools' section in http://www.asisi.co.uk/or1kecos.html will tell you how to do it; alternatively follow the build rules defined for the or32-rtems target in http://www.opencores.org/projects.cgi/web/or1k/ats as I believe the or32-rtems target doesn't have OS library dependencies like the or32-linux target (please correct me if I'm wrong).

I noticed the ECOS link doesn't have any info about building the
simulator. Forgive my ignorance but will the or1ksim run binaries built
using the ECOS configured tools? Does the or1ksim simulator need to be
configured in any special way in order for this to work?

1) You

I suggested. You need to make sure you change this: [snip] # > # Startup type # Selects whether code initially runs from ROM or RAM. In the case of ROM startup, # it's possible for the code to be copied into RAM and executed there. # cdl_component CYG_HAL_STARTUP { # Flavor: data # No user value, uncomment the following line to provide one. # user_value ROM # value_source default # Default value: ROM # Legal values: "RAM" "ROM" [snip] to this: [snip] # > # Startup type # Selects whether code initially runs from ROM or RAM. In the case of ROM startup, # it's possible for the code to be copied into RAM and executed there. # cdl_component CYG_HAL_STARTUP { # Flavor: data user_value RAM # value_source default # Default value: ROM # Legal values: "RAM" "ROM" [snip] The rest in 'my.ecc' should be OK but you must rebuild your 'tree' from scratch, so delete your old tree and do 'ecosconfig --config=my.ecc tree' again. You may also need to make sure or1ksim is configured appropriately in the sim.cfg file - Marko mentioned something about the mc (presumably memory controller) being configured correctly. Something like this in sim.cfg might be OK, but don't forget I have *not* tried this: section memory pattern = 0x00 type = unknown /* Fastest */ nmemories = 1 device 0 name = "RAM" ce = 0 baseaddr = 0x00000000 size = 0x02000000 delayr = 2 delayw = 4 enddevice end 2) You do not use the simulator part of GDB at all. You run or1ksim first, then run GDB, then connect GDB to or1ksim using 'target jtag jtag://localhost:9999' as mentioned before. GDB then thinks it's talking to 'real' hardware via a JTAG connection.
