Hi again,
correction to the below, the address calculated
is resulting in a 2 byte aligned value and not 4 byte as required.
(struct tcp_hdr *)((u8_t *)p->payload + IPH_HL(iphdr) * 4) = 0x0020b1fa
How about compiling all your source code into ARM mode and trying to
re-generate the problem? Maybe it can
give a clue. Moreover "adds r4,r4,#00" doesn't look like it can generate
a data abort. Maybe pipelening can be affecting
PC value. A whole code segment dissassembly can give more detailed info
about the error.
By the way, you didn't mention about your environment. OS,compiler?
I use SAM7X+LWIP+FREERTOS combination with GCC compiler and I'm quite
happy with it.
