Go <address> <mode>
Table 324. ISP Copy command
Command C
Input 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.
Return Code CMD_SUCCESS |
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
Description 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.
The boot block cannot be written by this command. This command is blocked when
code read protection is enabled. Also see Section 21.6
for the number of bytes that
can be written.
Example "C 0 268467504 512<CR><LF>" copies 512 bytes from the RAM address
0x1000 0800 to the flash address 0.
Table 325. ISP Go command
Command G
Input Address: Flash or RAM address from which the code execution is to be started.
This address should be on a word boundary.
Mode: T (Execute program in Thumb Mode) | A (Execute program in ARM mode).
Return Code CMD_SUCCESS |
ADDR_ERROR |
ADDR_NOT_MAPPED |
CMD_LOCKED |
PARAM_ERROR |
CODE_READ_PROTECTION_ENABLED
Description This command is used to execute a program residing in RAM or flash memory. It
may not be possible to return to the ISP command handler once this command is
successfully executed. This command is blocked when code read protection is
enabled.
Example "G 0 A<CR><LF>" branches to address 0x0000 0000 in ARM mode.
