Table 330. 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 331. 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.
Compare result may not be correct when source or destination address
contains any of the first 512 bytes starting from address zero. First 512 bytes
are re-mapped to boot ROM
Example "M 8192 268468224 4<CR><LF>" compares 4 bytes from the RAM address
0x1000 8000 to the 4 bytes from the flash address 0x2000.
