Hello, I tried to follow some example code given in the Hexagon_Doument_budle (Programmer's reference manual (V5/V55)), and got some run time errors. Could someone give me a help? Thanks Here is a description of the problem. According Section 2.3.8 Global pointer on page 45 and Section 5.8.4 Global pointer relative on page 87, I wrote the following assembly code.

.TEXT

.p2align 2

.globl myRE

myRE:

R7 =##0xd630

GP=R7

R6 =memw(GP+#200);

jumpr r31

when I tried to compile and run it, I got the following run time error message:

CRASH from thread 0!

I think the exception was: Error, cause: Misaligned @0xabde
