Thread 62288: Hi,I have STM32F4 interfaced with the external SRAM sized 512kx16array. The data words are 16bit wide, I'd like to use DMA for the speed. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer. 32-bit transactions have the same problem the DMA had, so I don't think it's so much a DMA problem as it is a problem with the FMC or a related area. 前几天看到开源电子论坛(openedv. 某些stm32芯片提供了备份sram,例如stm32f系列芯片有4k的备份sram。然而在使用过程中发现备份区域数据丢失!下面从stm32系列芯片提供的整个备份域来看看啥情况。电池备份域 首先,这部 博文 来自: 原点. MCU – STMicro STM32G031J6 Arm Cortex M0+ core-based MCU with 32 Kbytes of Flash memory and 8 Kbytes of SRAM, in SO8 package; Misc – 1x user LED, 1x reset/user push-button; Individual and breakable STM32 SO8 to DIL8 module (left) DIL8 socket to ease programming of the STM32 MCU (center) USB – 1x micro USB ST-LINK port. SOLVED: Backup SRAM for STM32 is wiped between resets. The STM32 has an 8MHz internal "HSI" oscillator, and a flexible PLL to multiple all clock sources. Make sure that the memory controller is configured properly in the initialization code though; on a Cortex-M3 like STM32 it would usually be through SystemInit(). The STM3240G-EVAL evaluation board is a complete demonstration and development platform for the STM32 F4 series and includes an STM32F407IGH6 high-performance ARM®Cortex™-M4F 32-bit microcontroller. SOLVED: Backup SRAM for STM32 is wiped between resets. MCU - STMicro STM32G031J6 Arm Cortex M0+ core-based MCU with 32 Kbytes of Flash memory and 8 Kbytes of SRAM, in SO8 package; Misc - 1x user LED, 1x reset/user push-button; Individual and breakable STM32 SO8 to DIL8 module (left) DIL8 socket to ease programming of the STM32 MCU (center) USB - 1x micro USB ST-LINK port. It features the ARM Cortex M4 32-bit STM32F401RET6 microcontroller and its pinout is similar to Arduino UNO and has many other additional pins to expand performance. 0 FUNCTIONAL DESCRIPTION 2. It appears that the code is copying the data from Flash memory to SRAM alright. So far so good (currently writing peripheral drivers for I2C), but I feel like I would rather write in C++ than C, mainly because of encapsulation and other features that C++ has to offer. Note that the pc register now contains a value in the 0x20xxxxxx range that indicates running from SRAM: Making your program run from SRAM does not consume FLASH rewrite cycles when downloading the program or setting breakpoints. The STM32 chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M33F, Cortex-M7F, Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Before using the SW-DP, an initialization sequence must be performed to establish communication and bring the SW-DP to a known state. – Reinstate Monica Jan 14 at 15:21.
