Extract the contents of the sam9-l9261-samba.zip archive to a temporary directory.
The board Linux installation can be restored using the SAM-BA script in
the sam9-l9261-samba.zip archive. Windows installation along with the
SAM-BA tool from Atmel are required for that.
Restoration procedure:
WARNING:
in the NAND partition.
TIP:
erasure can be spared. Open sam9_l9261_demo_linux.tcl and uncomment
the last few lines concerning the writing of NAND. Lines in TCL are
commented if the first character on the line is '#'. The result should be like
this:
.....lots of TCL code......
puts "-I- === Load the Kernel image ==="
send_file
$df_mapping(kernelOff) 0
#puts "-I- === Initialize the NAND access ==="
#NANDFLASH::Init
#puts "-I- === Erase all the NAND flash blocs and test the erasing ==="
#NANDFLASH::EraseAllNandFlash
#puts "-I- === Load the linux file system ==="
