The NationalChip GX6605S dev board is an evaluation board for the C-Sky architecture (which no openSUSE port exists for as of yet).

Technical details

  • NationalChip GX6605S SoC
    • 1x C-Sky CK610 CPU @ 574 MHz
  • 64 MB SDRAM
  • 4 MB SPI flash
  • 2x USB 2.0
  • 3 GPIO pins

Manual setup

GCC 9.1 includes some support for csky but not for ck610 (abiv1). Binutils 2.32 do include support for ck610.


The 5.2 kernel includes CPU and driver support for CK610 and GX6605S.

The hidden CONFIG_GX6605S_TIMER Kconfig option needs to be enabled to obtain any serial output from the kernel; earlycon is broken.

A gx6605s.dts file was still missing and needed to be hand-prepared.
