Neither of these worked for me:

opkg install omega2-script
opkg install kmod-pwm-mediatek-ramips

Unknown package 'omega2-script'.
Collected errors:

• opkg_install_cmd: Cannot install package omega2-script.

Unknown package 'kmod-pwm-mediatek-ramips'.
Collected errors:

• opkg_install_cmd: Cannot install package kmod-pwm-mediatek-ramips.

I had to add the packages to IMAGE_BUILDER_PACKAGES. opkg list does not report either of the packages

Tested in a clean clone of image builder

What firmware are you running? And what package repos do you have configured for opkg?
You will need both onion_openwrt_packages http://repo.onioniot.com/omega2/packages/openwrt-23.05.3/onion and onion_core http://downloads.onioniot.com/releases/23.05.3/targets/ramips/mt76x8/packages

Installing both packages works on the 23.05.3-20250121 firmware from Onion:

root@Omega-FBF4:/# uci show onion
onion.onion=onion
onion.onion.version='23.05.3'
onion.onion.build='20250121'

Following these directions, I am getting errors with the onion script. I am using the onion expansion board (NOT the evaluation board). I installed the opkgs as above and set the gpiomux for pwm:

root@Omega-1A39:/usr/bin# omega2-ctrl gpiomux get
Group i2c - [i2c] gpio 
Group uart0 - [uart] gpio 
Group uart1 - [uart] gpio pwm01 
Group uart2 - [uart] gpio pwm23 
Group pwm0 - [pwm] gpio 
Group pwm1 - [pwm] gpio 
Group refclk - refclk [gpio] 
Group spi_s - spi_s [gpio] pwm01_uart2 
Group spi_cs1 - [spi_cs1] gpio refclk 
Group i2s - i2s [gpio] pcm 
Group ephy - [ephy] gpio 
Group wled - wled [gpio] 

When I try to set the duty cycle/frequency with onion I get:

root@Omega-1A39:/usr/bin# onion -v pwm 0 90 10
sh: write error: Operation not permitted
sh: write error: Invalid argument
sh: write error: Invalid argument

Any advice on what to do next? System is

root@Omega-1A39:/usr/bin# !uci
uci show onion
onion.onion=onion
onion.onion.version='23.05.3'
onion.onion.build='20250205'
