MPU Configuration The Armv8-M Architecture allows up to 256 memory regions, but no implementation currently utilizes more that 16 regions. The configuration used in this tutorial supports up to eight regions. To confirm how many memory regions are in your M-profile device, software can read the...
在其他 SDK 示例(例如 UART_ECHO_LOW_RELATE_INTERRUPT)中移植 CDC 示例(CDC_ECHO_NTOOS)时、必须添加以下2个 MPU、否则程序将会运行。 原因是什么? [MV]非缓存区域被用于低级 USB 驱动程序、这是因为 USB IP 有其自己的 DMA 引擎。 我不确定是否需要0x60000000区域。 它用于...
