Can dual cores boot up at a same time?

Hi everyone,

 

Is there a way to boot up both cores baremetal at a same time? Or zynq only allows to start up in an amp way that core0 boots up first and core1 boots up next by core0 ?

 

Best Regads,

rj

In zynq-7000 FSBL only run on core0. Then FSBL can kick of the second core.

Thank you @denist,

 

Then, Can I load a single ELF to both cores by FSBL and let dual cores access the same piece of code? Is it doable?

 

Regards,

rj

You need to keep the read/write data sections independent but the read only section of code should be possible to have it in common.
