Hi, I'm doing kernel porting to arm926 based FPGA board, with very minimal setup. Only UART and timer devices are available as part of FPGA. Board details – Using ARM926e-js processor with 128MB SDRAM., Clock-33Mhz SDRAM Size = 128M CONFIG_PAGE_OFFSET = 0xc0000000 CONFIG_PHYS_OFFSET= 0x80000000 Loading the cramfs at 0x82000000 Start address for kernel is 0x80008000 Commandline(atags address) is 0x80000100 Kernel Lowmem = 32M HighMEM is not configured. Vmalloc_start = 0xC40000000 VMALLOC_END = Vmalloc_start + 64M = 0xC8000000 After mounting the CRAMFS filesystem, we are expecting a login prompt. But we are getting kernel panic message as shown below. Please help me in fix the issue. Kindly let me know if further information is needed. *Console message:* VFS: Mounted root (cramfs filesystem) readonly on device 1:0.
