I'm doing kernel porting to arm926 based FPGA board,very minimal setup. Only UART and timer devices are available as part of FPGA. Below are the details #define PLAT_PHYS_OFFSET 0x80000000 (with 128 MB SDRAM) #define CONFIG_PAGE_OFFSET 0xc0000000 Kernel command parameter has 64MB for mem (mem=64M) Memory layout: 0xc000_0000 - 0xc800_0000 (128MB virtual mapped SDRAM) initramfs from 0xC200_0000 - 0xC280_0000 (8MB) vmalloc is used from 0xc400_0000 - 0xc800_0000 CONFIG_HIGH_MEM not used device registers are accessed by using ioremap() calls If I enable data cache and debug with JTAG, Kernel ends up in data abort exception vector address after paging_init() call. I think there is some problem in memory setup.Can some one suggest how to overcome this...
