Hi, Teams

     Two years ago, we tried to use NuttX on satellites, 
and I started the work to porting nuttx to BM3803,  a SPARC V8 
architecture chip manufactured by BMTI(Beijing Microelectronics Technology 
Institute) which is based on open source CPU core----LEON 2  released by 
Cobham Gaisler.  about the SPARC V8 and LEON 2 see :

     BTW the chip of  AT697F of ESA(European Space 
Agency) is also based on LEON 2 see:

     I finished the whole work last year, Include 
architecture support code and board support code, I even completed and verified 
the Tickless OS mode and ELF file separate load on this SPARC V8 chip. Due to 
some reasons, the project leader did not adopt nuttx in the end, and I want to 
contribute code to the community.      

   

    The Toolchain of SPARC V8 is standard SPARC gnu gcc released 
by  Gaisler which can be download at:

     I initiated this discussion to seek your opinions, 
whether NuttX agree to include the SPARC arch in the scope of support ?      
      


Best regards,
Zou
