Hello,I have recently moved RAM from DTCM to AXI SRAM (so that I get more RAM).It then failed in dma example.After investigation I found out that the call to SCB_InvalidateDCache results in HardFault_Handler.I've changed it to use SCB_Invalida...
Hi,How to calibrate the adc... I am using Nucleo H743 and my H753 boards. Vref is 3.32V in nucleo, and 3.31V in my board.. when i convert the adc value by simply multiplying with Vre/65536, the result is almost greater than 11.mV (for Vin> 1.0000V) ...
Hi all, I would like to know whether the write access to external flash is possible when the code execution is from external flash? When I tried to write on external flash HAL function returns driver busy, since it's been used in memory mapped mode f...
I am having problem with writing program to internal flash memory. How to read from flash and write to flash? How to compare flash contents with uint8_t array contents? How to write uint8_t array contents to flash memory ? Please help
Dear STM team,we use and love your STM32H7. We would need approx. 50 NUCLEO-H743ZI, but no way to order this amount.It looks like, the H7 NUCLEO is not available (in the US) "anymore".What is the status of your H7 chips, esp. NUCLEO boards?Is my gues...
I upgraded the STM32CubeMx to 5.0, today. But it is very difficult to read the User Interface and Text in the Program. How i can get bigger fonts?I am developing programs with STM32H753 (my own PCB), and H743(nucleo 144) board... Is there any bigger ...
Hello,In stm32h7 I find examples/FLASH/WriteProtection example in EVAL folder, but the same example is missing from Nucleo folder.The protection is for the user flash (internal flash), so why is it missing from Nucleo ?(I rather do it in NUCLEO, so t...
In reference manual table 55 (Kernel clock distribution overview), there is a line for the DFSDM clock, indicating that it can be taken from either sys_ck or bus clock (which in the case of DFSDM would be APB2). That table also indicates that the max...
Hello,I do not find any encoding for the TSEL field in MDMA_CxTBR.. Probably they correspond to the list in MDMA-STM32H753_mdma1_v1_0_Modes.xml. But there may be reserved values like "54" in the DMA Mux requests , so they need to be documented somewh...
I am only using DMA to receive data continuously so when i want to receive data I am swithcing modes from full duplex to receive only. this whole pattern was working on F7 but not able to get it working on H7.I have followed some solutions given on S...
