I defined CFG_FLASH_EMPTY_INFO and ran some tests.  I tried erasing the last 
two sectors, both 0x10000 bytes in size, at FEFE0000 and FEFF0000.

After I erase FEFE0000 and do "flinfo", an "E" appears after the FEFE0000. 
When I copy data to FEFE0000 and do "flinfo" again, the E disappears.  So far 
so good.

However, no matter what I do, I can't get an "E" to appears after the 
FEFF0000.  In addition, the only way I can erase that sector is with "erase 
feff0000 feffffff".  Any other end-value gets me a "end address not on sector 
boundary" message.

Could this be a hardware problem?
