XMC7200 MPU Configuration Rainer2 Level 3 21 Jan 2025 Hi,we use the XMC7200 and use some DMA and different memory regions like a PSRAM at 0x60000000 with Keil and the Cypress/Infineon libs. However, depending on cache settings, there occur sporadic strange things e.g. with ethernet...
网络设备单板按功能可分为MPU、LPU、SFU。 网络设备在逻辑上分为以下三个平面:数据平面、控制平面和管理平面。 数据平面提供高速无阻塞的数据通道,实现业务模块间的业务切换。 控制平面完成以下功能:协议处理、业务处理、路由计算、转发控制、业务调度、流量统计和系统安全。 管理平面监控系统的运行状态,监控环境,处理日...
STM32CubeMX DDR 測試套件使用直觀的面板和菜單隱藏了與確定正確參數和初始化啟動相關的複雜性(請參考STM32CubeMX for STM32 configuration and initialization C code generation - User manual)。 為了快速設置要運行的 DDRSS,用戶只需提供很少幾個輸入參數即可完成配置。可以使用一些高級用戶模式和特殊功能(當它們對...
So I understand region configuration and MPU configuration but I don't understand Access Permission. (Priviliged and Unprivileged) Can someone explain me this or some code example, documentation etc.. Thank you for the help, Morgan Tags: mpu 0...
2. About MPU configuration, you can refer anyone of examples (e.g, helloworld) in source/xx.c reference code like below, `BOARD_ConfigMPU` function is for configration when doing init board hardware. int main(void) { char ch; /* Init board hardware. */ BOARD_ConfigMPU(); BOAR...
39、-M3/M4 and Cortex-M7 There are few differences at the MPU level between Cortex-M0+, Cortex-M3/M4 and Cortex-M7, so the user must be aware of them if the MPU configuration software has to be used. Table 5. Comparison of MPU features between Cortex-M0+, Cortex-M3/M4 and Cortex...
9. 切换到 Clock Configuration 标签页。10. 若软件报告时钟错误，可点击 Yes 自动修复。11. 输入 CPU、DDR、总线等的工作频率，系统会自动匹配合适参数。▲图 7 STM32CubeMx 时钟配置页面 12. 所有外设配置完成，即可点击 GENERATE CODE，开始生成工程代码。13. 若第一次使用，软件将提示是否下载 STM32CubeMP13...
/* Region 0 configuration: complete 32 bit address space = 4Gbits */ .regionId = 0U, .enable = 1U, .baseAddr = 0x0U, .size = CSL_ARM_R5_MPU_REGION_SIZE_4GB, .subRegionEnable = CSL_ARM_R5_MPU_SUB_REGION_ENABLE_ALL, .exeNeverControl = 1U, ...
可以通过display cpu-defend configuration all命令查看协议报文上送CPU的限速,回显字段Rate-limit(PPS)代表报文协议类型的限制速率,如果超过限制速率就会发生丢包。 可以通过display cpu-defend statistics[packet-typepacket-type]命令查看上送CPU报文的统计信息。根据报文类型查看丢失报文的计数。
MPU enabled 1.2 MPU Control and Configuration Registers There are four registers that are used to setup the individual MPU regions. The region base address (see Figure 2) which as the name suggests, is the address for the start of the MPU region. The region base register is shown in ...
