It looks like it will be. I have done a v850-elf-objektdump -h on the file
gdb_module.img and this ist the output.

gdb_module.img:     file format elf32-v850

Note, that i used a copy of the CEB Board package. I changed only the
relevant Flash/ROM sizes/adresses. I tried although the plain CEB Board
package and the .data and .ram_vectors are marked LOAD there too.
I used the Template/CEB - package stubs with additional option to build for
flash and the v850 variant SB1.

Where can i have influence on what is marked to LOAD ?

I found out, that SB1 and SF1 quite simillar. So i suppose i only need tho
change the memory range of our board to the ceb package.
