We didn't try to _build_ the ELDK under RH-8.0 yet. Did you encounter any problems? All feedback about required changes for building under RH-8.0 etc. is welcome! > So I'm trying to build a cute boot loader (for linux of course !) for my > custom board : As Jerry Van Baren already pointed out: use U-Boot :-) > - VME64x based > - PCC755 without L2 cache > - no PCI bus > - 2Mo Flash 29DL163 at 0xFFE00000 > - 128 Mo SDRAM at 0x0000000 > - a simple UART > - some analog I/Os Should be pretty straightforward, it seems. > - where and how to introduce the arch dependent source code in the source > tree of those boot loaders ? In U-Boot you will create a board specific configuration file in the include/configs/ directory and board specific source files, linker script etc. in a new directory board/<your_board_name> > - how to configure the Makefile to build a light exe ?

See the existing linker scripts as a model. I guess the easiest way to get started is to "clone" some similar board directory ... See the README that comes with the source. If you have questions, ask on the u-boot-users mailing list.
