The Raspberry Pi Compute Module 5 datasheet should be read in conjunction with this whitepaper.
https://datasheets.raspberrypi.com/cm5/cm5-datasheet.pdf

Raspberry Pi Compute Module 4 ተኳኋኝነት

For most customers, Raspberry Pi Compute Module 5 will be pin-compatible with Raspberry Pi Compute Module 4.
The following features have been removed/altered between the Raspberry Pi Compute Module 5 and Raspberry Pi Compute Module 4 models:

የተቀናጀ ቪዲዮ
The composite output available on Raspberry Pi 5 is NOT routed out on Raspberry Pi Compute Module 5
2-lane DSI port
There are two 4-lane DSI ports available on Raspberry Pi Compute Module 5, muxed with the CSI ports for a total of two

2-lane CSI port
There are two 4-lane CSI ports available on Raspberry Pi Compute Module 5, muxed with the DSI ports for a total of two
2x ADC inputs

ማህደረ ትውስታ

Raspberry Pi Compute Module 4’s maximum memory capacity is 8GB, whereas Raspberry Pi Compute Module 5 is available in a 16GB RAM variant.

Unlike Raspberry Pi Compute Module 4, Raspberry Pi Compute Module 5 is NOT available in a 1GB RAM variant.

አናሎግ ኦዲዮ

Analogue audio can be muxed onto GPIO pins 12 and 13 on Raspberry Pi Compute Module 5, in the same way as on Raspberry Pi Compute Module 4.

Use the following device tree overlay to assign analogue audio to these pins:

Due to an errata on the RP1 chip, GPIO pins 18 and 19, which could be used for analogue audio on Raspberry Pi Compute Module
4, are not connected to the analogue audio hardware on Raspberry Pi Compute Module 5 and cannot be used.

ማስታወሻ
The output is a bitstream rather than a genuine analogue signal. Smoothing capacitors and an ampየመስመር ደረጃ ውጤትን ለመንዳት በ IO ሰሌዳ ላይ lifier ያስፈልጋል።

የዩኤስቢ ማስነሻ ለውጦች

USB booting from a flash drive is only supported via the USB 3.0 ports on pins 134/136 and 163/165
Raspberry Pi Compute Module 5 does NOT support USB host boot on the USB-C port
Unlike the BCM2711 processor, the BCM2712 does not have an XHCI controller on the USB-C interface, just a DWC2 controller on pins 103/105. Booting using 1800t is done via these pins.

1/0 pin 92 is now set to w Button rather than sus PG this means you need to use a PMIC EN to reset the module.

The PRIC ENABLE Signal resets the PMIC, and therefore the SoC. You can view PRIC EN when it’s driven low and released, which is functionally similar to driving tus Po low on Raspberry Pi Compute Module 4 and releasing it.

Raspberry Pi Compute Module 4 has the added benefit of being able to reset peripherals via the nEXTRST signal. Raspberry Pi Compute Module 5 will emulate this functionality on CAM GPIOT.

GLOBAL EN/PHIC EN are wired directly to the PMIC and bypass the OS completely. On Raspberry Pi Compute Module 5, use
GLOBAL EN/PHIC Es to execute a hard (but unsafe) shutdown

If there is a need, when using an existing 10 board, to retain the functionality of toggling I/O pin 92 to start a hard reset, you should intercept the Button at the software level; rather than having it invoke a system shutdown, it can be used to generate a software interrupt and, from there, to trigger a system reset directly (eg. write to S)

Device tree entry handling a power button (arch/arm64/boot/dts/broadcom/bcm2712-rpi-cm5.dtsi).

Code 116 is the standard event code for the kernel’s KEY POWER event, and there is a handler for this in the OS.

Raspberry Pi recommends using kernel watchdogs if you are concerned about the firmware or the OS crashing and leaving the power key unresponsive. ARM watchdog support is already present in Raspberry Pi OS via the device tree, and this can be customised to individual use cases. In addition, a long press/pull on the PIR Button (7 seconds) will cause the PMIC’s built-in handler to shut down the device.

ዝርዝር የፒንዮት ለውጦች

CAM1 and DSI1 signals have become dual-purpose and can be used for either a CSI camera or a DSI display.

The pins previously used for CAMO and DSIO on Raspberry Pi Compute Module 4 now support a USB 3.0 port on Raspberry Pi Compute Module 5.

The original Raspberry Pi Compute Module 4 VBAC COMP pin is now a VBUS-enabled pin for the two USB 3.0 ports, and is active high. Raspberry Pi Compute Module 4 has extra ESD protection on the HDMI, SDA, SCL, HPD, and CEC signals. This is removed from Raspberry Pi Compute Module 5 due to space limitations. If required, ESD protection can be applied to the baseboard, although Raspberry Pi Ltd does not regard it as essential.

የኃይል በጀት

As Raspberry Pi Compute Module 5 is significantly more powerful than Raspberry Pi Compute Module 4, it will consume more electrical power. Power supply designs should budget for SV up to 2.5A. If this creates an issue with an existing motherboard design, it is possible to reduce the CPU clock rate to lower the peak power consumption.

The firmware monitors the current limit for USB, which effectively means that usb mas surrant, enable is always 1 on CM5, the 10 board design should take the total USB current required into consideration.

The firmware will report the detected power supply capabilities (if possible) via device-tree. On a running system, see /proc/device tree/chosen/poser/እነዚህ fileዎች እንደ 32-ቢት ትልቅ-ኤንዲያን ሁለትዮሽ ውሂብ ተከማችተዋል።

ተጨማሪ መረጃ

While not strictly related to the transition from Raspberry Pi Compute Module 4 to Raspberry Pi Compute Module 5, Raspberry Pi Ltd has released a new version of the Raspberry Pi Compute Module provisioning software and also has two distro generation tools that users of Raspberry Pi Compute Module 5 may find useful.

rpi-sb-provisioner is a minimal-input, automatic secure boot provisioning system for Raspberry Pi devices. It is entirely free to download and use, and can be found on our GitHub page here: https://github.com/raspberrypi/rpi-sb-provisioner.

pi-gen is the tool used to create the official Raspberry Pi OS images, but it is also available for third parties to use to create their own distributions. This is the recommended approach for Raspberry Pi Compute Module applications that require customers to build a custom Raspberry Pi OS-based operating system for their specific use case. This is also free to download and use, and can be found here: https://github.com/RPi-Distro/pi-gen. The pi-gen tool integrates well with rpi-sb-provisioner to provide an end-to-end process for generating secure boot OS images and implementing them on Raspberry Pi Compute Module 5.

rpi-image-gen is a new image creation tool (https://github.com/raspberrypi/rpi-image-gen) that may be more appropriate for more lightweight customer distributions

For bring-up and testing and where there is no requirement for the full provisioning system rpiboot is still available on Raspberry Pi Compute Module 5. Raspberry Pi Ltd recommends using a host Raspberry Pi SBC running the latest version of Raspberry Pi OS and the latest rathoot from https://github.com/raspberrypi/usbboot. You must use the ‘Mass Storage Gadget option when running rpiboot, as the previous firmware-based option is no longer supported.
