Reg: Enable arc to access the spi controller on I/O fabric on C1000

Hi

 

Please help me on the following queries

 

I have downloaded zephyr 1.6 and I have applied the patch https://gerrit.zephyrproject.org/r/#/c/8708/ to Enable arc to access the spi controller on I/O fabric.

 

I have few queries on the above.

 

1.      I have declared CONFIG_SPI in the prj.conf for the ARC project and SPI access is working.

Can I declare the CONFIG_ SPI on the prj.conf on the X86 also ?

My query is simultaneous SPI access is possible via ARC and X86 ? or should we declare CONFIG_SPI in any one of the cores only.

 

2.      After reset of C1000, the code in the ARC is getting executed first, Followed by x86 .

By default can I make some settings to delay the execution of ARC code  other than task_sleep ?

 

 

     

 

 

Best regards
Mahendra
