My use case is similar. I just did smoke test and there is another issue. T
est
code is executed from RAM (0x10000000) where it try to call firmware stored
at
flash (in this example function at 0x3779)
BLX instruction was replaced by BL, but at immediate address is generated
thumb->ARM switch instruction "BX PC" which cause hard fault
10000a94: f000 f898 bl 10000bc8 <___xxx_from_thumb> # ok BLX repl
aced
by BL
...
___xxx_from_thumb():
10000bc8: 4778 bx pc ; hard fault
10000bca: 46c0 nop ;
10000bcc: e51ff004 ldr pc, [pc, #-4] ; 10000bd0
<_farAway_from_thumb+0x8>
10000bd0: 00003779 andeq r3, r0, r9, ror r7
ld just generate these __from_thumb stubs which is not what we wont at Cort
