Subject: tb_flush during softreset

Hi,

We are seeing issue when fetching tb cache, any suggestions for debug would be 
helpful.

Issue: Post soft reset of the core, bootloader(running over different cpu) 
reloads the program memory and releases the reset. At that point CPU crashes 
after first tb cache fetch.

Note: cpu's have mmu disabled. So no tlb_flush_pages are called.

Question: Is tb_flush called when bootloader has written to program memory of 
the target cpu ?

Thanks & Regards,
Sai Pavan
