Why do they use Broadcom silicon for their wireless stack?
One of the engineers who worked on it worked out a deal with Broadcom to simply reuse the design and market it toward education instead
Does something like this exist?
They are extremely unstable, and if you want any kind of moderately reliable deployment of an RPi, you need to use a watchdog timer to reset the device if it freezes. Except - guess what - the watchdog timer itself is broken on the RPi! (As of the last time I tried this, iirc with an RPi 4) Either it's busted in hardware or the driver is broken. Most semi-high-reliability devices built using RPis have elected to use external watchdogs, which is super annoying and would not be necessary on a correctly designed SoC.
Their clocking and boot schemes are also totally insane garbage, with random peripherals breaking if you change the GPU clock, and with the GPU silicon running the bootloader or something ridiculous like that.
I would prefer almost any other ARM SoC to the BCM used in the RPi.
