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
