Yep that looks like a 7I76+7I78 configuration
with just one PWMGen for the 7I78 on P2
but this is the load line that generated that dmesg:
loadrt hm2_pci config="num_encoders=2 num_pwmgens=2
num_stepgens=3"
Thats a pinout file not a dmesg log
Its the output of the --readhmid command you asked for. I just copy
pasted it all, including the mesaflash command you can see at the
top of the paste.
the dmesg file shows the 2nd pwmgen, but the dir signal is
permanently grounded.
Thats with the original 5i25_7i76_1px2d.bit file installed.
Um no, there is only PWM 0 brought out
What pin is grounded?
P2-05. With either bitfile installed, 3 5i25's tested.
Thats expected to be low since its PWM 0 PWM pin
It does seem to have a harmless inconsistency
(2 PWMgen inside but only 1 wired to the output)
Cheers, Gene Heskett
