The roadblock has always been the MMU. Vanilla Linux won't work without it, and uCLinux is always in some strange phase of support for newer architectures if it's supported at all.
I found a decent port of uCLinux to the Cortex-M3 once, but the host core was 120 MHz and it was pretty much a science experiment and not much more.
- linuxlizard 7y agoI can't tell from the datasheets and the description. Does this ucontroller have an MMU?
- jng 7y agoIt’s an A9, same as on Xilinx Zynq 7000 series, 32-bit ARM core with full MMU.
- xfer 7y agoNo the zynq chips have a cortex-A9, which is armv7, this is armv5. It still does have a MMU.
- carlosperate 7y agoFor comparison, the Raspberry Pi 1 had an armv6 core.
- jng 7y agoOh, my bad, I misread the datasheet, read "A9" where it says "ARM9". Thanks for the correction.
- RealityVoid 7y agoI expect that it being a M3 it had a MPU but not am MMU.
