Is that correct code ?

 [00011038] 204825FF     strcsd        r2, [r8], #-5F
 [0001103C] 00000001     andeq         r0, r0, r1

Should it be more something like this:
 [00011038] E59FC000     ldr           ip, [pc]  ; PC+8+0 = 00011040
 [0001103C] E59CF000     ldr           pc, [ip]
 [00011040] 00012030     andeq         r2, r1, r0, lsr r0
