Description
Example
Command
Input
Return Code CMD_SUCCESS followed by four 32-bit words of E-sort test information in ASCII
Description
K
None
It is to be interpreted as <byte1(Major)>.<byte0(Minor)>.
This command is used to read the boot code version number.
M
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.
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 |
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
"M 8192 268468224 4<CR><LF>" compares 4 bytes from the RAM address
0x1000 8000 to the 4 bytes from the flash address 0x2000.
N
None
format. The word sent at the lowest address is sent first.
This command is used to read the unique ID.
