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.
Freeing init memory: 76K

Panic meaasge:
Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
