[Lesson 04] Problem calling process function #226

Closed Andre-Fonteles closed 3 years ago

Andre-Fonteles commented 3 years ago

Hello. I'm getting the following exception when the function "process" is about the be executed by one of my tasks:

SYNC_INVALID_EL1h - 04, ESR: 0x0000000086000000, Address: 0x000000000008153C

where 0x8153C is the address of the first instruction in my process function.

Would anyone have a lead on what is going on?

I'm using RPi 4, for what is worth it.

Thanks!
