The flash is not dead. I could flash uboot using RVI debugger without
any problem. Basically I load two uboot images onto RAM using RVI- one
to run from RAM and writes the second image to flash. This is always
succussfull. ONce the uboot is written to flash, and reboot the board, I
get the error that the "flash is not errased". 
Today I tested with the top-of-git version. Still have the same problem.
Anyone have experienced this problem before.
