Hi,
I'm using Arm Musca-A1 and I am stuck with the configuration of UART1 to non-secure. From my understanding, to configure the peripheral to a non-secure access setting one should configure SAU and give access to it in the
On Cortex-M processors it's a little different. Nothwidstanding I was able to solve the problem. In fact I had the right assumption (you need PPC + SAU to configure a peripheral as NS), but I had some code running on Flash before I loaded my own to SRAM (which is where I am to execute). This issue is solved.
