I am trying to run the sims on a ubuntu system and I get:

johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ ./run
Cleanup...
=======================================================
| Start simulation: mpy_basic
=======================================================
../bin/msp430sim: 103: Bad substitution
johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$

I can hack around this but it then wants to compile stuff. Does the msp430 toolchain run on linux
or are they windows only?

Hi John,

MSPGCC can be installed on Linux.

I did built it from source with the help of the following wiki:
http://sourceforge.net/apps/mediawiki/mspgcc/index.php?title=Linux_installation

Can you tell me more about the "bad substitution" problem ? It works properly on my machine but I would be interested to know what caused the problem on your side.

PS: don't forget to make sure that the compiler executables are in your path

Oliver,
It is a shell issue. It doesn't work with /bin/sh but does with bash. I am using ubuntu 10.4.
What is that line supposed to accomplish?

johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ sh
$ pmemsize=`grep PMEM_SIZE_ pmem.inc | grep -v ifdef | grep -v "//" | cut -d'_' -f3`
$ echo $pmemsize
2
$ pmemsize=${pmemsize/p/.}
sh: Bad substitution
$ bash
johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ pmemsize=`grep PMEM_SIZE_ pmem.inc | grep -v ifdef | grep -v "//" | cut -d'_' -f3`
johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ echo $pmemsize
2
johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ pmemsize=${pmemsize/p/.}
johne@hallway2:~/ocsvn/openmsp430/core/sim/rtl_sim/run$ echo $pmemsize

Hi John,

This is a substitution command which will replace the character "p" with "."
This operation is required when a memory size of 2.5kB is selected through the verilog define: DMEM_SIZE_2p5_KB

Until today, I always thought that sh and bash were the same thing... however, a bit of googling taught me that "/bin/sh" is typically linked to the default shell of your system. On my openSuse system, it is linked to "/bin/bash" and on Ubuntu/Debian it seems to be "/bin/dash".

In any case, thanks a lot for your good feedback :-)
I'll update all the bash scripts headers with "#!/bin/bash" instead of "#!/bin/sh"

Olivier

That was to old for my ubuntu 10.4

This worked:
