Hi All.


We have a Custom Board (Rev1) with the Am29DL163DT Flash and encounter the following problem:

We cannot program the last two Sectors of the Flash (Offset 0x1FC000 and 0x1FE000). Any other Sector can be programmed.

The board is designed using freescale's EVB-example.

When using the original 5235 EVB everything goes. (Flash here is Am29PL160CB)

Flashing a newer Custom Board (Rev 2) with the S29GL064 works fine.


Did someone encounter similar problems with Flashs or can give some hints.


Thanks in advance.
