Chapter 32: LPC176x/5x Flash memory interface and programming
32.7.12 Read Boot Code version number
32.7.13 Read device serial number
32.7.14
Compare <address1>
<address2> <no of bytes>
Table 584. ISP Read Boot Code version number command
Command K
Input None
Return Code CMD_SUCCESS followed by 2 bytes of boot code version number in ASCII format.
It is to be interpreted as <byte1(Major)>.<byte0(Minor)>.
Description This command is used to read the boot code version number.
Table 585. ISP Read device serial number command
Command N
Input None.
Return Code CMD_SUCCESS followed by the device serial number in 4 decimal ASCII groups,
each representing a 32-bit value.
Description This command is used to read the device serial number. The serial number may be
used to uniquely identify a single unit among all LPC176x/5x devices.
Table 586. ISP Compare command
Command M
Input Address1 (DST): Starting flash or RAM address of data bytes to be compared.
This address should be a word boundary.
Address2 (SRC): Starting flash or RAM address of data bytes to be compared.
This address should be a word boundary.
Number of Bytes: Number of bytes to be compared; should be a multiple of 4.
Return Code CMD_SUCCESS | (Source and destination data are equal)
COMPARE_ERROR | (Followed by the offset of first mismatch)
COUNT_ERROR (Byte count is not a multiple of 4) |
ADDR_ERROR |
ADDR_NOT_MAPPED |
PARAM_ERROR |
Description This command is used to compare the memory contents at two locations. This
command is blocked when any level of code read protection is enabled.
Example "M 8192 268435968 4<CR><LF>" compares 4 bytes from the RAM address
0x1000 0200 to the 4 bytes from the flash address 0x2000.
