Description
Example
C
Flash Address(DST): Destination flash address where data bytes are to be
written. The destination address should be a 256 byte boundary.
RAM Address(SRC): Source RAM address from where data bytes are to be read.
Number of Bytes: Number of bytes to be written. Should be 256 | 512 | 1024 |
4096.
SRC_ADDR_ERROR (Address not on word boundary) |
DST_ADDR_ERROR (Address not on correct boundary) |
SRC_ADDR_NOT_MAPPED |
DST_ADDR_NOT_MAPPED |
COUNT_ERROR (Byte count is not 256 | 512 | 1024 | 4096) |
SECTOR_NOT_PREPARED_FOR WRITE_OPERATION |
BUSY |
CMD_LOCKED |
PARAM_ERROR |
CODE_READ_PROTECTION_ENABLED
This command is used to program the flash memory. The "Prepare Sector(s) for
Write Operation" command should precede this command. The affected sectors are
automatically protected again once the copy command is successfully executed.
This command is blocked when code read protection levels CRP2 or CRP3 are
enabled. When code read protection level CRP1 is enabled, individual sectors
other than sector 0 can be written.
"C 0 268468224 512<CR><LF>" copies 512 bytes from the RAM address
0x1000 8000 to the flash address 0.
P
Start Sector Number
End Sector Number: Should be greater than or equal to start sector number.
CMD_SUCCESS |
BUSY |
INVALID_SECTOR |
PARAM_ERROR
This command must be executed before executing "Copy RAM to Flash" or
"Erase Sector(s)" command. Successful execution of the "Copy RAM to Flash" or
"Erase Sector(s)" command causes relevant sectors to be protected again. To
prepare a single sector use the same "Start" and "End" sector numbers.
"P 0 0<CR><LF>" prepares the flash sector 0.
