Freeplay CM3 --> CM4S - Lanium - 09-09-2024 This thread will record my adventure swapping out a raspberry pi CM3 with a CM4S that i found on my Freeplay CM3 device. The benefits of moving from a 3 to a 4 seem to be pretty good: https://www.reddit.com/r/RetroPie/comments/fmdx0t/pi_3_vs_pi_4_worth_it/ https://www.reddit.com/r/raspberry_pi/comments/14gtjx1/pi_3_vs_pi_4_emulation_performance/ I bought a CM4S that i found on ebay. A straight swap from CM3 to CM4S didn't work. I got a small error about unable to load something. is it running?. Avoiding the troubleshooting for now, i am imaging a new SD card and will start from a fresh image. RE: Freeplay CM3 --> CM4S - Lanium - 09-09-2024 I would like to go with the most up to date version of Raspbian: Operating system images (https://www.raspberrypi.com/software/operating-systems/) Raspberry Pi OS Lite
and manually install RetroPie using this: Manually Install RetroPie on Raspbian/Raspberry Pi OS (https://retropie.org.uk/docs/Manual-Installation/) Then plan to customize using this: Manual Instructions - How To Add Freeplay Functionality To Raspbian RE: Freeplay CM3 --> CM4S - Lanium - 09-09-2024 I used the Raspberry Pi Imager and edited the configuration to apply a custom hostname, setup a user / password, configure WiFi, and enable SSH with keys to my raspbian image. looked over the config.txt and updated with the setttings published here: https://forum.freeplaytech.com/showthread.php?tid=5392&pid=10384#pid10384 along with: core_freq=400 RE: Freeplay CM3 --> CM4S - Lanium - 09-09-2024 Upon the first boot, i get a white screen and after a few minutes it shutdown. I believe that this is normal. I was not able to start it up a second time. I inserted the SD card and looked at the config.txt file and the last few lines were missing: Code: # Disable the ACT LED on the Pi Zero. Appended them back on and saved the file and after reinserting the SD card, it was able to start back up and the green LED lit up. RE: Freeplay CM3 --> CM4S - Lanium - 09-09-2024 ok, so that didn't work - trying to use the bookworm raspbian image. I flashed the most up to date freeplay image for the CM3 and it has booted successfully to a prompt. I think that there was an issue with the scripts since i changed the default user from pi. RE: Freeplay CM3 --> CM4S - Lanium - 11-13-2024 looks like the filter to use in the config.txt is [board-type=0x15] per https://forums.raspberrypi.com/viewtopic.php?t=338978 i noticed that the usb port wasn’t working with the cm4s plugged in. it might require a connection to a pin or a specific overlay. “pulldown the pin USB_OTGID.” https://raspberrypi.stackexchange.com/questions/147300/usb-not-working-for-cm4s#147379 “add dtoverlay=dwc2,dr_mode=host to the config.txt Then reboot the Pi. Now you should be able to use the built-in USB 2.0 ports!” https://www.jeffgeerling.com/blog/2020/usb-20-ports-not-working-on-compute-module-4-check-your-overlays i also found a review of the cm4s compared to other cm versions: https://www.tomshardware.com/raspberry-pi/raspberry-pi-compute-module-4s-review RE: Freeplay CM3 --> CM4S - Lanium - 11-13-2024 i found this type of installation nice: https://www.cytron.io/tutorial/installing-retropie-on-cm4-emmc-with-retroflag-gpi-case-2-swift-performance-actionclear-all-cache_wpnoncef3e213e2f7 instead of requiring a custom image, it just uses a retropie image and provides a patch to install in the boot partition for the custom changes. i am not sure if this would be possible to convert. i will investigate. |
