Hi, Sorry if you find this post stupid, but I'm quite new in Linux. To learn on Linux kernel, I've decided to port it on particular board with (very) limited resources and based with a 4KC processor core. As far I see, I need at least a couple of mega bytes of memory to achieve my goal. Unfortunately the only way to get this amount of mem is to execute linux in memory that can only be accessed through KSEG2 and KSEG3 ! Here is my board's mapping: Physical Memory Map: start size type ----------------------------- 0x20000000 - 8MB - SDRAM 0x30000000 - 16MB - FLASH 0x40000000 - 16MB - FLASH 0x50000000 - 2MB - SRAM I looked into the memory init code and I don't think that it's possible to run linux in a segment different from KSEG0. Am I wrong ? I've noticed a CONFIG_MAPPED_KERNEL macro but it seems that it's only used to replicate kernel from mapped memory to KSEG0... Thanks for your answers. Découvrez le nouveau Yahoo!
