[Oberon] FPGA Oberon - Modules.rsc

[thomas.kral at email.cz]

Hi Andreas,



Thank you, nice work of yours!




In the chapter 14.2 it hints that linker is almost identical to `Modules.
Mod' loader, except it links statically into a file, rather than into 
memory.




Addresses are relocated with origin 0H, from a fixed start of Oberon 
partition?




I also found found some  boot linking modules in native oberon souce files.


./src/x86/Unix/BootLinker.Mod

./src/NO/BootLinker.Mod





Was I close?




What would be also  interesting to decompose `prom.mem' to understand how 
this file could be produced.

It seems to have 361 lines each ascii encoded long word. Ends with C7000000,
 lines 362-490 are zeros .

Are these RISC machine instructions?







Many thanks

Tomas

The book Project Oberon does not describe the way the inner core itself is built (it only mentions that a “boot linker”is needed for that) or loaded onto the boot area of the local disk, nor are the tools to accomplish this published.

A minimal set of the Oberon building tools can be found at:

Hi Joerg,
I was rereading the chapter 14 again, I realise the boot over RS232 is 
triggered by a switch, but I still do miss the point, how do I build the 
inner core, and Oberon0. In the text there is a reference to boot linker. 

Many thanks

Tomas

The inner core is at a fixed location on the disk.

The boot process is described in chapter 14.1:
