Hello,what is the best way to run some of the demos provided by CubeMx on a custom HW?Probably like this: Generate demo code for an evaluation board. Then merge the generated initialization code for the custom board into the demo code folder?Or can C...

Hello,SDRAMs are available in different speed option -5, -6 or -7. IMHO this specifies the max. SDRAM clock at CAS=3, but SDRAM can configured via CAS parameter to be used at a lower clock frequency.Alliance Memory -7 for example can be configured CA...

Hello,I used CubeMX for a design for H75x in LQFP176.I was able to configure SDCKE0+SDNE0 signals of SDRAM Bank 1 to PC2_C and PC3_C.Now I wanted to configure a SDRAM test using JTAG boundary scan but the JTAG tool manufacturer claims that these PCx_...

Hello,I succeed to run all demo programs of the H7 performance suite (STM32CubeExpansion_Performance_H7_V1.0.0) except the QSPI single mode demo (8 - D1_QuadSPI_Single - D1_DTCM) on STM32H753I_EVAL2. But I can run the dual mode demo (9 - D1_QuadSPI_D...

Hello,I want to execute code located in external 16bit NOR FLASH e.g. on a STM32H7x3 evaluation board.I can run the NOR FLASH demo (erase, write, read flash) successfully but have no clue how to create and flash code.After googling 2 days I found ple...

@Andrew Neil I'll give a try at least for the custom F4 board. Thanks @Pavel A. H7R/S, MP1 oder MP2, just an idea what comes next. I guess CubeMx will generate initialization code them and all uC provide kind of compatible HAL layer which makes it e...

Ok, I got the ACK from ST that the burst feature is not supported in asynchronous mode. This explains why code execution from parallel asynchronous NOR is slower than from xSPI NOR and is not recommended.I think I'll keep on using the 2MB flash µC's ...

The final goal is to port an non-HAL based application from M4 to H7. My idea is now to redesign the application using the STM32 HAL first so I am able to compile for both platforms (an probably a future platform, e.g. MP2?). As I understand now, the...

@Andrew Neil This gives me an idea how to generate code for two different HW platforms using the same application code.Unfortunately, I do not have the IOC file for a STM32H743/753_EVAL2 board. I found this thread here but it seems that the mentioned...

I'm not sure if I fully understand your answer regarding tAC.According to your definition, access time is the time span between the rising edge of the first CL and the first rising edge after the last CL cycle.Regarding the reference manual, the FMC ...
