Description
Example
C
Flash Address(DST): Destination flash address where data bytes are to be
written. The destination address should be on a flash word (4 bytes) boundary.
Writes on a row boundary (128 bytes) are preferred as they can be performed more
efficiently. The total number of bytes copied must be ≤ 4096 bytes.
RAM Address(SRC): Source RAM address from where data bytes are to be read.
Number of Bytes: Number of bytes to be written. Must be a multiple of 4 bytes.
SRC_ADDR_ERROR (Address not on word boundary) |
DST_ADDR_ERROR (Address not on a word boundary correct boundary) |
SRC_ADDR_NOT_MAPPED |
DST_ADDR_NOT_MAPPED |
COUNT_ERROR (Byte count is not 4 bytes) |
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 is enabled.
"C 0 268467504 512<CR><LF>" copies 512 bytes from the RAM address
0x1000 0800 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. The boot
block can not be prepared by this command. To prepare a single sector use the
same "Start" and "End" sector numbers.
"P 0 0<CR><LF>" prepares the flash sector 0.
