Mesa 7i96s with 7i74 and additional pwmgen was created by Lennart
Hi,
I am currently running a 7i96S with a 7i74 sserial card (7i96s_7i74d.bin), but I need a second hardware PWM generator (pwmgen.01) on Step 5 (or any available physical Step pin) to modulate my Raycus fiber laser with a variable duty cycle. Is it possible to configure the 7i96s like that ?

7I96S+7I74 firmware with Step4 (last stepgen of 0..4) replaced with PWM 1
(Dir 4 is just GPIO)

Hello again,Somehow I'm struggling to flash the configuration:
returns a success message, but running
afterwards shows absolutely no change.I've tried it with my newly generated bin file (
), but also with various other configurations. I made sure to execute
and also did several hard power cycles (power resets). I checked the board status using
, and it looks like fallback is not active.Does anyone have an idea what could be blocking the update, or what I might be missing?
I attached my terminal outputs.Thanks in advance!
Code:
mesaflash --write
Code:
--readhmid
Code:
7i96s2p_7i74d.bin
Code:
--reload
Code:
--verbose

Not sure, works for me:
mesaflash --device 7i96s --addr 10.10.10.10 --write 7i96s2p_7i74d.bin --reload
md5sum 7i96s2p_7i74d.bin
b77b9faf82730e3acf82c2cdcba6e022 7i96s2p_7i74d.bin
mesaflash --device 7i96s --addr 10.10.10.10 --readhmid > 7i96s2p_7i74d.txt
gives me:
mesaflash --device 7i96s --addr 10.10.10.10 --write 7i96s2p_7i74d.bin --reload
md5sum 7i96s2p_7i74d.bin
b77b9faf82730e3acf82c2cdcba6e022 7i96s2p_7i74d.bin
