Note: arm32 / ARMv7 embedded boards produced in the 2020+ era still exist (see SAM9x60).
In case anyone wants to keep the ARM9 assembly/core but also wants modern Linux 6.12 support.
The Nintendo DS was a complete package though: screen, buttons, sound, etc. etc. But I'm still amused at the long term life of embedded programming and how ARM9 cores with ARMv7 assembly still is in production today.
Indeed, and for more clarification, as Arm's naming scheme easily causes confusion :
ARMv7 and ARMv4, used by the ARM7TDMI processor core in the GBA, NDS and 3DS, are not the same instruction sets. You can indeed find processor cores in recent microcontrollers/SoCs implementing Armv7 or Armv7-M.
The SAM9x60 has an ARM926 core, which implements the Armv5TEJ instruction set, similar to the DS' ARMv5TE instruction set implemented by its ARM946 core. The former has Jazelle while the latter doesn't.
See https://en.wikipedia.org/wiki/ARM7#ARM7TDMI and https://onlinedocs.microchip.com/oxy/GUID-B822915F-C375-4172...
ARMv7 and ARM7 look very similar, but ARM7 is ARMv3, and ARM9 is ARMv4. Similar names are very misleading here.
