Programming a Boot Image into Boot Flash
This operation is very similar to the write operation. Program your driver according
to the following description
1)
. A code example for this routine is given on page 4-
36.
1. Erase current content of boot image area by writing “eras” into SYNC
word
2. Wait for completion
3. Write offset of I/O buffer relative to beginning of memory window into
COFF field (in big endian data format) to define I/O buffer in area avail-
able as I/O buffer (01C40000
16
- 02000000
16
)
4. Write programming offset into CADR field
This offset is relative to the boot image area in the boot flash device, not
relative to the beginning of the boot flash device itself.
5. Write number of bytes to be programmed into CSIZ field
6. Store data to be written into I/O buffer
7. Start operation by writing command “flsh” into SYNC field
8. Wait for completion (see the “Return Codes” section on page 4-19)
1) Using the primary booter for programming the boot flash requires also a programming routinge for start-
ing the primary booter.
