    I think Eclipse ThreadX is a great option (https://github.com/eclipse-threadx/threadx)

    Its might be the most used ThreadX on the market in the professional space (due to its history), but its quite frankly stupid simple to use.

    It was initially developed by Express Logic, then partnered tightly with Renesas, Then sold to Microsoft, and then transferred to the Eclipse foundation for good.

    They also provide NetX(duo), FileX, LevelX, UsbX and GuiX with full source and the same licensing afaik. Personally I don't care for UsbX or GuiX.

  • Considerations for a long-running Raspberry Pi

    Comment by the developer who attempted to create open firmware, https://github.com/christinaa/rpi-open-firmware/issues/37

    > a lot of corners were cut to save time leading to what I believe is poor ARMv7+ Cortex IP integration (GIC, TrustZone, etc). So I stopped working on it. If those things were not the case (GIC working, "TZPCs" working, security working as intended, instead of NS forced to high on bridge, at least in my understanding) I would still work on it ...

    ARM isn't a second class citizen on this platform, it's a third class citizen since BCM2709 (again this is an opinion) ... the features I wanted to tinker with the most are absent by design (cutting corners) and I'm not willing to resort to SW emulation of them through clever uses of the VPU.

  • Microsoft opens sources ThreadX RTOS used in Raspberry Pis

    Sure, and it's been done: https://github.com/christinaa/rpi-open-firmware - but that doesn't involve ThreadX source, just some standard reverse engineering work. ThreadX is really the least interesting part of this whole operation in terms of the Raspberry Pi.

    It's very cool that ThreadX has been open sourced as it offers an additional battle tested and mature alternative to FreeRTOS for new projects, but in terms of reverse engineering or open sourcing the Raspberry Pi VideoCore blob, it's pretty much a non-event IMO.

    I guess you are thinking of this issue:

    https://github.com/christinaa/rpi-open-firmware/issues/37

    Since then the project moved to a new maintainer (not me), who worked on it slowly but surely. They need new contributors though.

    They have (https://github.com/christinaa/rpi-open-firmware). The problem is that almost nothing works (no video or even USB). The sequel to "f you, NVIDIA": f you, Broadcom.

    There was! And it even booted Linux in some capacity: https://github.com/christinaa/rpi-open-firmware

    > every chip is very different from one another

    Eh, the usual embedded SoCs are not that different from each other — ARM GIC, ARM timer, lots of Synopsys Designware crap for SDMMC/XHCI/PCIe/etc.

    For many SoCs it's totally feasible to make standards-compliant firmware, e.g. for the Rockchip RK3566 there is https://github.com/jaredmcneill/quartz64_uefi

    And SoCs from the networking world (Marvell, NXP) are typically supported by upstream EDK2.
