Hi,1.As it is mentioned in CM4 user guide and also explained in tutorial, 0th bit of PC is directly loaded to T bit.And CM4 supports only thumb state ISA.To execute/decode instructions in Thumb state 0th bit of PC should be 1 which means PC should al...
Hello,As per CM4 guide and TRM of Nucleo f446re,interruot vector table is array of function pointers and each pointer holds the entry address(initial address) of each IRQ_handler, Where interrupt IRQ_number is used for indexing.While debugging I fail...
Hello !I have to admit that I am stumped on this problem, I've been trying to make it work for the past few days.My issue is with an STM32F301K8T6 (LQFP32) and its ADCs : I have two reflective optical sensors (ITR8307) that are connected to ADC_CHANN...
Hello,I'm using LPUART1 (STM32U0) for modbus communication and using STOP2 mode to go sleep until new modbus query has requested.Strange things happen, on console I can see prints like "Target is not responding, retrying...".Here is my clock configur...
Hi Team,Could you please guide me on how to correctly configure the internal Flash memory for the STM32U5 series? Specifically, I would like to understand how to:Modify the Flash start and end addressesSet appropriate lengthsPartition the Flash to al...
I've be trying to learn CAN for the past few days for a project using 2 Nucleo F103RB and 2 CAN transceivers. I made a very basic code using normal mode and without using RTR. Now I want to learn how to code using RTR, can someone help me please?(I ...
Hello. I have a custom board with F105RCT7. The summary of my problem is the USB interface is not working at all. The computer does not detect anyting. The board is configured as a VCP device. I have a Nucleo-H743ZI-2 board and done some tests with....
Hello,I have two questions regarding the STM32U0 series and the RM0503 reference manual:1/ HSISYS Divider ConfigurationIn RM0503, for the STM32U0 series, it is stated that HSISYS is a clock derived from HSI16 after division by a value from 1 to 128.T...
Hi all,I wanted to make a post to shine some light on how to configure the HRTIM DMA on the STM32F3348-DISCO (and probably other ICs w/ HRTIM capabilities).A few posts I've seen have boasted the same solution, but have convoluted the use of a single ...
Hello,I found some discrepancy in BOR configuration for STM32U083CCT6 processor between reference manual [1] and HAL implementation [2]. It concerns BOR_LEV[0:2] bits (bits 10:8) in FLASH_OPTR register. The RM [1] talks of four levels (000: 1.7 V, 00...
