Exploring the versatile capabilities of ComputeBlade's M.2 expansion port and its support for various devices. We'll take a closer look at NVMe drives support, AI accelerators, FPGAs, Network cards and Graphic cards. For advanced users we will show the difference between PCIe 2.0 and PCIe 3.0 and how to enable it on Raspberry Pi Compute Module 5.
Not everyone knows that the Raspberry Pi CPU has a built-in Watchdog.
It's basically a time bomb that will reboot the CPU if its timer is not reset. And the operating system, in case of normal operation, sends a reset command every preset time interval. It's just a great solution and surprisingly easy and flexible to customize.
With the release of CM5, it is now possible to double the speed of the PCIe bus on the Compute Blade when working with the Compute Module from Raspberry Pi. It's quite easy to do, and so far all the tests I've done show high stability of the solution.
