Hi.
Attempting to enable&use watchdog in 8343; but run into Assembler
(v.2.15) problem in cpu/mpc83xx/start.S:424
....
/* and reset it */
li r4, 0x556C
sth r4, SWSRR at l(r3)
li r4, 0xAA39 <-------- gas barks here, 0xAA39 > 0x8000
sth r4, SWSRR at l(r3)
which I do not understand, since I thought 'li' was an UNsigned 16bit
load. I can work around it in a kludgey way with.
lis r4, 0
ori r4, r4, 0xAA39
sth r4, SWSRR at l(r3)
but wonder if one you PowerPC assembler gurus could offer better suggestion.
Thanx.
-dbu.
