[Luis sent me the .srec file so I could take a look at it.]
The problem is the length of the first line of the srec file. The first
line is 80 characters long, which is too long. The cryptic error message
is because the line passed into the decode routine is truncated to 80
characters and therefore shorter than advertised by the S026 header on that
first line.
According to the s-record format description I have, "an S-record will be
less than or equal to 78 bytes in length." This first line of the file
violates that restriction. Who is to blame does not really matter, but
interestingly enough, the contents of that first line include:
../code/light-brait-with-debug.srec
So one solution would be to use shorter filenames...
But assuming you want to fix firmdl.c, you have two lines to change:
Change line 298 from:
if (count > 37 || len > count * 2 + 4)
to:
if (len > count * 2 + 4)
Change line 414 from:
while (fgets(buf, 80, file)) {
to:
while (fgets(buf, sizeof(buf), file)) {
That will make firmdl.c compatible with the long filenames put into the
description records by the linker.
Alternatively, download the latest firmdl.c from:
