Hello everyone,
Board: Altera DE2 with cyclone2 NOMMU Sysfile: system0.ptf from DE2_NET Example (v 1.6 Terasic Homepage) System: uclinux from nios2-linux-20090730.tar up to date git version, fresh build (make menuconfig, make) I followed the InstallNios2Linux guides from nioswiki. At bootup or after dmesg it says: Memory available: 5012k/2898k ram, 0k/0k ROM (1938k kernel code, 960k data) Thats a little bit strange to me ... make vendor_hwselect SYSPTF=DE2_NET.ptf Looks the following: --- Please select which CPU you wish to build the kernel against: (1) cpu_0 - Class: altera_nios2 Type: f Version: 6.0 Selection: 1 --- Please select a device to execute kernel from: (1) sram_0 Class: sram_16bit_512k Size: 524288 bytes (2) sdram_0 Class: altera_avalon_new_sdram_controller Size: 8388608 bytes (3) epcs_controller Class: altera_avalon_epcs_flash_controller Size: 2048 bytes (4) cfi_flash_0 Class: altera_avalon_cfi_flash Size: 4194304 bytes Selection: 2 Hmm whats the problem? Is it a problem? Feedback would be great!
