// There is a single Intel StrataFLASH device on the IXDP425, supported via the
|
| 49 |
|
|
// generic Strata flash package. By default this is the 28F128J3 which is a
|
| 50 |
|
|
// 16MByte device, arranged as 128*128K blocks with no boot blocks, 16-bits
|
| 51 |
|
|
// wide. There is a 32-byte program buffer and locking is supported.
|
| 52 |
|
|
//
|
| 53 |
|
|
// But CFI is used to determine Flash geometry as the part is fitted in a socket
|
| 54 |
|
|
// to allow replacement with other StrataFLASH parts.
