Try to disable trace32 data abort trigger,when you are debugging linux,there will be many reasonable data abort generated, just ignore them. 在 2012-3-14，23:52，"pcuser p" <pcuser.mails@gmail.com> 写道：
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...
Thanks, pcuser
