AM5728: register access in IPU2

Part Number: AM5728
Other Parts Discussed in Thread: SYSBIOS

Dear Champs,

My customer wants to access CTRL_CORE_MMR_LOCK_2 and CTRL_CORE_IPU2_IRQ_33_34  registers in the IPU2.

Should they register the memory addresses of these registers to be accessed by IPU2 while linux is running on A15?

Their SW SDK is Processor Linux SDK v6.3.

Thanks and Best Regards,

SI.

    Hi Sung-IL,

    Linux does not touch or own the IPU2 Crossbar, and these need to be managed by the IPU2 software in general.

    SYS/BIOS provides a IntXbar module (ti.sysbios.family.shared.vayu.IntXBar) that provides API to program the registers.  

    regards
