Yes, of course. We have to make different configuration files -- one for each board. But, do we really need different board directories with almost the same code in it? Ex.: My current Stratix patch is based on the Cyclone board, because both boards are equal in context of u-boot basics need. Only the second serial i/f differs (not needed til now). So there will be more identicalness than differences for both boards. But note: this does not apply to the APEX board. The APEX board has different Flash, less SRAM, only SODIMM SDRAM, no second seriel i/f (in standard32 case), no CF, less LEDs, and ... to many differences and it's right, for APEX we should make a new board directory with it code inside. What's your opinion? FYIO: I plan to make an hardware overview for all known NIOS devkits by Altera (APEX 20k200, Cyclone 1C20, Stratix 1S20 and 1S40). br, Stephan > > U-Boot for Nios development kits should always support the > default "out-of-the-box" Nios configuration (for the altera boards, > this is typically the "standard 32" config).
