Hi Liming,

I've tested another workaround - Move the FD file to a higher RAM location (originally, it is loaded into 0x50000, now it is at 0x10000000)
With the FD file moved to 0x10000000, the decompression works every time, even with bigger FD. I've attached the my FD file in the mail. 

Thanks
Tien Hock
