About STREX/LDREX instructions on LS1043A

Question asked by hehe yellowriver on Jan 19, 2017

Does LS1043 support STREX and LDREX instructions in A32 mode?


There is data abort when I execute strex/ldrex instructions on the LS1043A development board.

For exemaple:

            pantest_loop: b pantest_loop
            ldr  r2, =0x80180000
            ldrex r1, [r2]      # there will be dataabort exception


Could you please give me some suggestions or comments? Many thanks!
