Thank you. I updated the file to this:

/lm32uart@0x80006000/reg 0x80006000 0x100
/lm32uart > int int0 /lm32cpu
/lm32timer@0x80002000/reg 0x80002000 0x80
/lm32timer > int int1 /lm32cpu

And that works with gdb using the tar sim command below.

tar sim --hw-file lm32_evr.conf --memory-region  0x08000000,0x4000000

But nothing comes out from the same executable using run

lm32-rtems4.11-run --hw-file lm32_evr.conf --memory-region 
0x08000000,0x4000000 .hello.exe

Does that make any sense to you?
