Hello - I am working on a safety critical application using the STM32L431VC that requires the VREF+ voltage rail to be powered off of a different voltage rail than the main VDD and VDDA rail. The VDD and VDDA voltage rails are being generated by a s...
I'm using the STM32H745I-DISCO board.I'm trying capture on the ADC and feed straight out on the DAC, triggered by a timer.The timer is working, and the ADC is getting data that looks sensible.I can see data reaching the DAC data register, but the out...
The Hardfault Exception sometimes occurs during system operation.The register and stack values are as follows after the hardfault exception occurrence.The MSP 0x20003780 points to the stack area storing the register information(LR, PC etc) at the mom...
hi,I am getting hardware fault in stm and i found why it is happening .Now i want to rewrite the below function like clear the Int abd executing next instruction of stack.can i do like that .if possible is there any source code available for that.vo...
Hi everybody,I use a STM32L476RG. I'm trying to write 4 bytes in the flash memory on a PVD IT.I can write/read in the flash, it works.I've programmed my PVD on level 6 (2.9V) and BOR level is at 1.7V. I've used AN4718 to design a vbat system with a s...
What is the difference between parts “STM32F429ZGT6�? and "STM32F429ZGT6TR"? W found from the datasheets,"*** = programmed parts,TR=tape and reel" .We think,“programmed parts�?should not be the same as "tape and reel".So the “TR�? really means？Can th...
in RM0008 Rev 21; page 1083; Table 220. Flexible SWJ-DP pin assignment"The default state after reset is “000�? (whole pins assigned for a full JTAG-DPconnection). Only one of the 3 bits can be set (it is forbidden to set more than one bit)."I don't u...
We have an STM32H750 ARM Cortex M7 processor in our product and are compiling C code using STM32CubeIDE. We want to have default code in FLASH that is able to run the default application by itself but which can also load an updated application to AXI...
1.in the manual "AN5050", What's the meaning of "memory type"? Does this mean that OCTO only supports these four types of memory chips? The flash I used is "IS25LP064A", Does the OCTOSPI support this flash?2.How to set the "DEVSIZE"? if the flash si...
Hi! I'd like to reconfigure power supply settings on our custom board with an STM32H742. I've done some research reading reference manual and application note. CubeMX has generated code with the following two calls I am using inside of SystemCl...
