Hi, With the media base address of : 0x26800000 the following should work: # load -v -r -m tftp -h 192.168.1.100 -b 0x200000 vmlinuz # exec -b 0x200000 -l 0x400000 -c "console=ttyS0,115200 root=/dev/nfs ip=192.168.1.6 nfsroot=192.168.1.100:/mnt/image/ rw memmap=exactmap memmap=128K@128K memmap=615M@1M vmalloc=586M" (if you have a 2GB board you can add memmap=1023M@1024M to make use of the extra 1GB as highmem). You should not be using memmap=32K@0 memmap=226K@64K. The problem probably comes from your CEFDK version. Try updating your CEFDK to the PC25 CEFDK on cocoms website for Thatcher. There are separate versions for 1GB and 2GB boards and you need to use the gen4.5_cocom.bin not the gen4.5_intel.bin. In the readme file there is a snip of the CEFDK info that should be printed, check the build date is the same to check if your CEFDK is the same.
