Message-ID: <30734554.post@talk.nabble.com> (raw)
Hello everybody,
I have a question pertaining to almost every lowlevel_init.S. The code goes
like
/*make r0 relative the current location so that it*/
/*reads SMRDATA out of flash rather than memory*/
ldr r0,=SMRDATA
ldr r1,_TEXT_BASE
sub r10,r0,r1
I couldn't relate the code to comments made ahead of that(how does TEXT_BASE
- addrof(SMRDATA) yield the location of SMRDATA in flash. I totally dint get
it. Please enlighten me. I greatly appreciate any response.
Thanks,
Vamsi
