Nov 11, 2022 · I am having a hard time to get the Waveshare 5inch DSI LCD display working with the CM4 and the official I/O board. I followed these steps: Plug the Compute Module 4 on the CM4 I/O board; Flash the last Raspberry OS 64 (Bullseye) with desktop to the eMMC. Test it working through the SSH, enable all the interfaces (including VNC) on the ...

Feb 23, 2022 · I have a Raspberry Pi CM4 IO Board and want to access it via serial console. Do I need to use external USB to TTL Rs232 Module Converter Serial Cable Adapter(USB to TTL Rs232) to connect serially? Or can I use micro USB cable and connect it to micro USB connector on IO board? This is the pin diagram of CM4 IO Board

Jul 22, 2021 · If anyone has any experience of getting a single camera module working with a CM4 and IO board please could you give me some brief instructions on what I need to do. I am somewhat at loss here. I understand that the binary blob is to configure the Pi GPIO hardware when the GPU initializes, but this is about the limit of my understanding.

Apr 6, 2021 · I'm using Raspberry PI OS image is 2021-03-04-raspios-buster-armhf-lite and I spotted in the product sheet for the Raspberry PI CM4IO (Compute Module 4 IO board) that it was i2c-10 assigned for the fan.

Mar 8, 2022 · I have a RPi CM4 Lite and IO Board. I am trying to access serial console using USB to TTL Rs232 Module Converter Serial Cable Adapter Serial cable. I have connected Black wire to pin 6(Ground), White to pin 8(TxD) and Green to pin 10(RxD), Red +5V is not connected to any pin of IO Board. I could see log messages during boot.

Jul 6, 2023 · I used the CM4 IO board to connect the CM4 via USB from my macOS laptop. Next, I used the usbboot repo, and the instructions in the official guide to flash and update the firmware and install the Raspberry Pi OS (tried both 32 and 64 bit). Note that I fit the jumper on nRPI_BOOT as mentioned while flashing.

Nov 28, 2020 · Once you have completed the hardware / software development it is normal to do away with the board and use the modules themselves - sometimes in a carrier board but sometimes direct to the main circuit board. The boards do simplify tasks (such as flashing emc with code) but long term are not necessary. Do you need them from get-go?

Mar 13, 2024 · I have a Compute Module IO Board Plus designed by WaveShare. When I'm plugging in a CM3+, USB works fine. I also have a board I designed that has the same schematic as the WaveShare. USB communication works as well when I plug in a CM3+. Current Problem: I'm using this same setup with a CM4S.

Aug 25, 2021 · If its learning than the Raspbery PI CM4IO or the Waveshare CM4 IO PoE offer all the interfaces in a straight forward and large development format. Share Improve this answer

Jul 25, 2023 · Some pins need voltage reference, so you would need produce those. Some pins have to be driven low or high. This will spiral out into design of a custom carrier board. Then your only method of accessing it is over WiFi or shell from UART. Short answer is yes, with extra custom board and tone of knowledge.
