Subject: [U-Boot] Strange arm9 behaviour reading long(s) not aligned to 4 bytes boundary
Date: Sat, 24 Jan 2009 17:18:48 +0100 (CET) [thread overview]
Message-ID: <26134646.40551232813928358.JavaMail.defaultUser@defaultHost> (raw)
Hi,
I have something like this on a 32 bit little endian arm9 board (SAM9
L9260):
char buffer[] = { 0, 1, 2, 3, 4, 5, 6, 7 };
long A = * ( (long*)
buffer );
long B = * ( (long*) (buffer + 2) );
printf("A: %08x B: %08x", A,
B);
I would expect that A = 0x03020100 and B = 0x05040302
instead I get the
right value for A but B is 0x01000302 or something like this but anyway not
what I expect.
Is there something wrong on the board? It seems that only 4
bytes aligned long are read correctly.
Thank you in advance,
Antonio.
