I have two yagartos:
(23.12.2010, mifi) NEW
(13.08.2010, mifi) OLD
Unfortunately, I can't show all of my code,
but I can try to explain the problem.
size = orcf("0:fpga.bin", buff);
// if (size != 54664) BKPT;
crc = crc32C(buff, size);
ArgPrint(text, "%D", crc);
This piece of code causes malfunction.
What is the malfunction? Well, I'm a bit tired now
and honestly can't tell...
What I can tell is that the new version works
if I uncomment the IF line or if I add a space in
ArgPrint's 2nd param, like this: "%D ".
I've checked the return value inside orcf
and its always 54664.
I guess it has something to do with memory address.
(I have 32MB of SDRAM, so stack corruption is not very likely)
I've compared listings of OLD and NEW version.
There are 3 diffs:
1. memcpy is completely different.
My "compare files" prog shows every line as non-matching.
2. because NEW memcpy is larger, almost every
address is changed a bit:
20004024: 2001acd8 .word 0x2001acd8 <- this addr changed
3. in one of the functions, R1 is replaced with R2.
Everything else is THE SAME, therefore I believe it has
something to do with memcpy.
The sym files shows all addresses as equal, except those
found after memcpy.
As I said, I'm tired now to do further testings.
This may have nothing to do with memcpy, after all...
