I am using the FM4-S6E2CC-ETH board with Keil uVision 5.28. The sample code (fm4_sine48_intr.c) builds but when I debug the code stops at:
LDR.W R0, =0xE000ED88 ; CPACR is located at address 0xE000ED88
I cannot hear anything with the headphone connected to the board. There should be a 1kHz tone out of the board.
Thank you for coming back to share the solution you found with the community.
