RE: [U-Boot-Users] Memory Testing (Flash,EEPROM)

It makes no real sense to perform a write testing on flash memory, for example, as you must erase the flash to write it, and erase it again to write it again, and the fact that you can write it now is no guarantee that it is still erasable the next time.
IMHO, the point is not to test the chip, but to test the wires to the chip, for industrial purpose.
For the other matters, the customer will find it out by himself anyway :*)

You don't want to do this in software - software can only test certain functions, but not all connections. For that you want to do standard hardware verification procedures like boundary scan etc.

Indeed ;-)
