Hello, Michiel
I compile your version (based on binutils-2.18, gcc-3.2.3) on Linux
(ubuntu) and it works, thank you!
Addressing goes well with the 20bit
Finally, there is however a problem when I defined a section in fardata
(0x10500) the compiler truncates the address (0x0500)!
10c18: d1 42 00 05 mov.b &0x0500,2(r1) ;0x0002(r1)
I have not defined this section in the linker script, but like this:
-Wl,--section-start=.fardata=0x10500 \
-Wl,--section-start=.fartext=0x10C00
I'll test it with a linker script later ...
I was not able to compile your version (innovents) under Windows (cygwin
1.7)!
I have problems with the bintutils-2.18, If you have any tips to come,
shows me please !
It's the next step ...
For Milhai I put my test files below
Bye!
