As you might have thought: No it is not.
Full name: Motorola S-Record Format
The S-record standard is as follows:
S<type><length><address><data....><checksum>
S4<length><address><name>,<checksum>
Where:
type
is the record type. Where:
0 starting record (optional)
1 data record with 16-bit address
2 data record with 24-bit address
3 data record with 32-bit address
4 symbol record (LSI extension)
5 number of data records in preceeding block
6 unused
7 ending record for S3 records
8 ending record for S2 records
9 ending record for S1 records
length
is two hex characters. This defines the length of the record
in bytes (not characters). It includes the address field, the data
field,
and the checksum field.
address
is 4, 6, or 8 characters. Corresponding to a 16-, 24-, or
32-bit address. The address field for S4 records is always 32 bits.
data
Are the data bytes. Each pair of hex characters represent
one byte in memory.
name
Is the symbol name. The symbol is terminated by a ','.
checksum
Is the one's complement of the 8-bit checksum.

| Hi, Is the kernel size simply the size of the legos.srec file? I thought so initially, however my legos.srec file is 18800(or close to) and im pretty sure ive allocated more than than 19k using dynamic memory. Obviously this is more than 32k in (...)
