RTC hrtc.Init.AsynchPrediv & hrtc.Init.SynchPrediv = 10 Registers
Can somebody please help me. The code below is initializing the RTC. The clock works I can set and read time and date no problem. Somehow if I change these register: hrtc.Init.AsynchPrediv = 131; hrtc.Init.SynchPrediv = 10; It has no imp...
STM32F407 RAM Interface impedance matching
Hi Team,As we are going to use RAM – IC CY62136EV30 (TSOP-44) in our new project with ST micro STM32F407ZG (LQFP-144).Do we need any impedance matching for 6-layer board?Can you please suggest the same. Crystal frequency we taken 16MHz for the MCU.Th...
SIGTRAP when reducing HCLK
I'm in the middle of attempting to reconfigure the clock tree on my STM32F303K8. The old clock tree looks likeThe new clock tree looks like The old clock tree works fine. The new clock tree always fails on boot; not always in the same address but alw...
Resolved! CANFD not working with FIFO1, only with FIFO0, STM32G0B1KEU6
Hi Team, Could you please assist me with the following situation: CANFD is working with FIFO0, but not with FIFO1, same config, using STM32G0B1KEU6. I am using same channel, FDCAN1. I will attach both files for refference. Thank you in advance, A...
Resolved! STM32H747 Memory Mapped NOR-Flash AT25SF128A
Hi,I'm trying to implement an external loader for the Arduino Giga R1 board with AT25S128A 128Mbit of external flash. After following the guide given in the external loader repo, I'm running into the problem, that I can erase, write & read from the m...
ADC "shorting" analog input to GND
We're using the following circuit to measure a battery voltage @ 20 kHz for use in motor control.We are having some issues though, where the ADC suddenly starts measuring 0 V (0 in the data register) and gets locked in this state. In this state, we a...
Resolved! STM32H573 PB14
In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
Resolved! STM32H7S7L8H6H XSPI instability
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Resolved! STM32U5 FATFS with FreeRTOS
Hi,I'm attempting to write to an SD Card using a Riverdi STM32U5A9 display board. Since TouchGFX natively uses FreeRTOS, I'm attempting to keep it within FreeRTOS. Porting to ThreadX has caused it's own issues which I have in a separate thread. In...
