我们就以IMXRT为例,来说明一下,1052是外挂SPI Nor,首先上电后,内核的boot(固化)就直接读取Nor的前4K,来初始化flash的频率等等,如果是外接SDRAM,还需要再读4K DCD数据来初始化SDRAM; 接下来,code段里的数据一直存在Nor里,等待内核读取即可,接着需要手动把data段的数据从Nor拷贝到RAM里,为什么要拷贝?应为data段...
OK1052-C开发板基于NXP公司i.MXRT1052 跨界处理器设计,搭载ARMCortex-M7内核,集微控制器的低功耗、易用性与应用处理器的高性能、高扩展性于一体。采用核心板+底板分离结构,主频528MHz,SRAM 512 KB(TCM),SDRAM 16MB/32MB,QSPI-Nor Flash 4MB/16MB 。
Hello NXP TechSupport : I am using the MIMXRT1052 chip,Mount three devices using the SEMC bus,One SDRAM and two FPGAs,The chip select signal of SDRAM
凭借这种关键设计特性,跨界处理器的有效性能将远远超出 MCU 同等产品。方便扩展存储芯片,如外扩SDRAM、flash等。
I've been struggling for days on a hardfault problem.I have a bunch of preproduction custom boards with: - RT1052 MCU- external SDRAM chip- external SPI Flash (quad)- i2c IO expander- audio codec (with SAI and i2c lines). i2c bus for audio is different from i2c bus for IO expander...
The interface supported includes SDRAM, NOR Flash, SRAM, and NAND Flash, as well as 8080 display interface. SJC System JTAG Controller System Control The SJC provides JTAG interface, which complies with Peripherals JTAG TAP standards, to internal logic. The i.MX RT1050 processors use JTAG port...

I did the test and, when I am in debug mode running in SDRAM, I can access the Cypress Hyperflash, erase and write and read back to check the data. So I am sure the Hyperflash is still working. I searched the internet to find another solution but I didnt find yet. I am open ...
