Honored ContributorWhen I compile the kernel I see something like this:
UIMAGE arch/nios2/boot/vmImage Image Name: Linux-2.6.34-00692-g5bc7853-dirt Created: Fri Mar 25 12:05:26 2011 Image Type: NIOS II Linux Kernel Image (gzip compressed) Data Size: 1187727 Bytes = 1159.89 kB = 1.13 MB Load Address: 0xC0800000 Entry Point: 0xC0800000 Kernel: arch/nios2/boot/vmImage is ready Load address is 0xC0800000 But when try download image the load address is different : ios2-download -g images/zImage Using cable "USB-Blaster [USB 1-1.3.3]", device 1, instance 0x00 Pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 3529KB in 19.3s (182.8KB/s) Verifying C1800000 ( 0%) Verify failed between address 0xC1800000 and 0xC180FFFF Leaving target processor paused He's trying load to address C1800000. Why? :( Addresses are: # define RESET_ADDR 0xc0800000 # define FAST_TLB_MISS_EXCEPTION_ADDR 0xc1800000 Is my nios_sopc bad created? arch/nios2/kernel/vmlinux.lds.S: . = DDR2_TOP_BASE | KERNEL_REGION_BASE; @gabrigob: I have the same. in nios.h I have: # if defined(CONFIG_NIOS2_MMU) # include <asm/default_mmu.h> /* Added compability mode with macro names from "old" design... * FIXME: we should really fix drivers instead. but this makes it * easier to switch between old and new design... */ # define CONFIG_ALTERA_CYCLONE_II # define DDR2_TOP_BASE DDR_SDRAM_BASE # define DDR2_TOP_SPAN DDR_SDRAM_SPAN # define EXT_FLASH_BASE FLASH_BASE # define EXT_FLASH_SPAN FLASH_SPAN # define TIMER_1MS_FREQ SYS_CLK_TIMER_FREQ # define TIMER_1MS_BASE SYS_CLK_TIMER_BASE # define TIMER_1MS_SPAN SYS_CLK_TIMER_SPAN # define TIMER_1MS_IRQ SYS_CLK_TIMER_IRQ # else # error "No FPGA configuration selected" # endif
