Hi,
I had a DMA project running on the Raspberry Pi3+ that output a signal on PWM1. The memory for the data and CB were allocated to VC memory using the Mailbox property interface.
Now I wanted to move the project to the Raspberry Pi 5. After research, the mailbox function for allocating memory is no longer available.
What options do I have to reserve uncached memory for the DMA now?
