The day of Raspberry Pi CM5 release, I published a mini review of the Raspberry Pi Development Kit for CM5 showing how to assemble the kit and boot Raspberry Pi OS, and I also ran sbc-bench benchmark to evaluate the performance. Sadly, the Broadcom BCM2712 CPU did throttle during the test meaning cooling was not optimal when the CM5 IO board was inside the IO Case and the Compute Module 5 was only cooled by the fan. So today, I’ll repeat the same test with other cooling solutions namely the official Raspberry Pi Cooler for CM5 (that’s a heatsink only),  and EDATEC’s CM5 active cooler similar to the active cooler for the Raspberry Pi 5, but designed for the CPU module. But before that, I’ll do some house cleaning so to speak since last time, I booted Raspberry Pi OS from an NVMe SSD and I noticed the camera did [...]

The Rockchip RK3588 is one of the most popular Arm SoCs for single board computers, and while good progress has been made with regards to mainline u-boot and Linux support, the SoC is quite complex and it takes time to port all its features even though it was first teased in 2020 and the first Rockchip RK3588 SBCs were introduced in 2022. While the simpler Rockchip RK3566 and RK3568 SoCs are already fairly well supported in mainline Linux, more work is needed to upstream code, and as noted before in posts and comments here, Collabora keeps track of the status on Gitlab, and the company recently posted an article about the progress and future plans related to upstream Linux support for Rockchip RK3588.
