Resolved! Can't connect to the MCU via STLinkV2 [ST-LINK error (DEV_CONNECT_ERR)]
I have made a PCB with the STM32C011F6P6 on it and am trying to program it via an ST-LinkV2. While trying it out yesterday, it connected just fine with the cube programmer. Now I am trying to do the same thing again, but both the cube programmer and ...
Resolved! What are the Memory Addresses for SRAM1 and SRAM2 on STM32U0
The Reference Manual for STM32U0 series MCUs, RM0503 Rev2, specifies, in table 2 on page 57, that SRAM starts at 0x2000 0000 and ends at 0x2002 9FFF. This is a contiguous region with a size of 168KB. However, the Size column shows 40KB. This docum...
Resolved! STM32H753 SVD File FDCAN Discrepencies
I downloaded the STM32H753 SVD file from https://www.st.com/resource/en/svd/stm32h7-svd.zipI have found a number of discrepancies between this file and RM0433 (reference manual)That leaves me wondering if this file is outdated and a more recent, cor...
No DFU detected, usb device not recognized code 43
I am trying to create a custom keyboard, and I was trying to flash my board with stm32f070c6t6 MCU in DFU mode using cube programmer, but I keep getting "no DFU detected" (of course while pulling BOOT0 pin high).Also, every time I plug my device into...
Resolved! Internal Pull up STM32G4 series
Hello,I am using the internal pull up for the input pins, but when read the port status using the program, it always reads 0 instead of 1. I expected it to read 1 and if make that pin grounded it shall read 0.
Resolved! Problem with external oscillator : not able to flash anymore
Hello all, I made my first "from scratch" STM32 board (in the past I always used demo boards). I cabled JTAG connector : I was able to flash and debug from CubeIDE in SWD mode with a Stlinkv2, but did not succeed in JTAG mode, don't know why but ...
STM32 SDRAM Access Results In HardFault
Hello, I am using STM32F469BIT with W9812G6KH-6I TR SDRAM and no matter what I did, I could not write to or read from SDRAM since MCU goes into hardfault whenever i want to access SDRAM. I configured FMC according to this article. I am running SDRAM ...
Resolved! DMA receive, with circular buffer: Incoming data is not copied in buffer on time
I have set up a UART as receiver. I use circular buffer to copy the data in. The code pretty much works ok with one exception:If the last byte of incoming data frame is to be saved in index 0 (UARTRx[0]), the data appears at this address AFTER the bu...
STM32H757 IC does not boot if VSSMPS connected to VSS of the IC.
Hi,I am using STM32H757 in one of our projects and operating the IC to power through Internal SMPS only and made the connections as mentioned in the datasheet. The VSSSMPS was connected to VSS of the IC which is a regular practice. With this connecti...
