Resolved! Memory issue
Dear community membersWe are using Quad SPI in stm32l476 while having a memory to read data but we are facing an issue. Garbage values when entering memory mapped mode.why is that?Thank you.

Resolved! While sending data on to USART1, I always get FEIF DMA errors. Why?
So I am setting up the DMA for USART1 tx on a STM32F4 on each transfer, and busy wait for it to be done (no interrupt) by polling TC. DMA2_Stream7->NDTR = len; DMA2_Stream7->PAR = (uint32_t)&(USART1->DR); DMA2_Stream7->M0AR = (uint32_t)str...
Resolved! FOTA/FUOTA Delta firmware with STM32
I'm new to the STM32 and I wanna know how can I make a Delta firmware ? If anyone have an idea or have already worked on it, please share it with me.Otherwise, is it possible to make a program that take the initial firmware and only update the addres...
Resolved! I can't post question because I am new
It keep saying that I can't have links in my post because I am new. There are no links in my post.And because I am new, of course I have questions :(Garrett
SWV working on Nucleo-F446ZE but not on Nucleo-F767ZI or STM32F769-Disco
I've created three (nearly) identical test projects, one for a Nucleo-446Ze, one for Nucleo-767Ze and one for a STM32F769-Disco. They are all nearly identical: 1) Trace Asynchronous SW 2) FreeRTOS 3) A single task created for each user LED to blink t...
Resolved! DMA transfer is completed before transmitting all the data to SRAM (or data is corrupted)
I am currently working on a touch screen for one of our products. I built an LCD intel 8080 driver with the FMC and it's not working with DMA.The image is only partially flushed to the screen. It seems that there is some kind of limits to the transfe...
Proper way to send 16 bit SPI data
I need to send 8 bit and 16 bit data with my 32f769. I found a register modification routine to change the bits from 8 to 16 and back. I checked the SFRs and it works (changing the bits that is),When I transmit 8 bit data, all is fine. I can send ...
Resolved! CAN BUS INTERRUPTS - HAL_CAN_RxFifo0MsgPendingCallback never triggers / I never get the Rx Interrupt.
Hello,My setup is as follows: I have an STM32F469I MCU connected (via SN65HVD230 CAN Board) to the CAN bus of an STM32MP157c-EV1 MPU board which is running Debian.My goal is to make the MCU send CAN frames periodically to the MPU, and with the CAN Ut...
Resolved! Is there a better way to generate a variable frequency using DMA and TIM2 than what is described in AN2820 Paragraph 2.2.1 Page 13/14?
It is doing exactly what I want, It is ramping up the frequency at the start, staying steady for some period of time, and then ramping down. In my case, I need up to 38400 steps. And I want to count steps, not time. My first thought was to have a big...
