2 years ago Hi,
Thanks for reporting this. Seems like what's happening is that xPortSetInterruptMaskFromISR is not getting inlined at -O0, and therefor during Cache_Flush()->esp_ipc_isr_stall_other_cpu() we end up accessing a function in flash while the cache is disabled.
We'll fix it!

create example, then change optimization level to "debug without optimization(-O0)", download and run, it will crash.
Change optimization level to default "debug (-O0)", it will be OK again.
