I tried to use STM32G0B0 DMA1-1/2 for I2C1, DMA1-3/4 for USART1, DMA1-5/6 for I2C2. Channel 1 to 5 work properly. Channel 6 (I2C2-TX) works but TC INT doesn't fire. I tried switch I2C2 -TX from channel 6 to channel 7 or to DMA2- channel1 to 7, none w...
Hi Team, We are using the STM32H753VIH6 in our design. We are connecting the Realtek RTL8364 through RMII interface.Connections are in the attachment and we have validated link between the two.I have captured the waveforms , but the voltage span look...
Hello, i have a question regarding the analog comparators and the STM32G0B0VE. As stated in the "Product Selector" found under STM32G0x0 Value line - Products the STM32G0B0VE features 2 comparators: But when i look into the reference manual RM0454 ...
I am trying to upload the code to my target STM32F407 but below error is showing up. I tried some of suggestions but problem is still there. I am using Version: 1.15.1. Debug log file also attached. 1) Doing Mass Erase of flash,2) Updating ST Link ...
I'm using STM32H743VGT6 QSPI drive an AMOLED screen. AMOLED read sequence need IO0 line send and receive data.(Picture 1) But I checked the H743 Reference manual, it says in the single mode, IO0 just output, not input.(Picture 2) How do I fix to make...
Hi, there; I am migrating the DCMI from stm32h743 to stm32u575, on the stm32h743 chip, I can make the dcmi work perfectly, but on the stm32u575 chip, I cannot make the DCMI work, neither the GPDMA for DCMI. Anyone met the same issues? The codes are g...
When I use usbuser to power the Nucleo-H563ZI board, I have add jumper in the usbuser at JP2.Then ld5 and ld7 light up, but the mcu firmware doesn't start properly. I need to add jumper in the CHGR at JP2 then the mcu firmware can start. According to...
Hello,I am running into a weird behavior where EE_ReadVariable32bits call in EEPROM EMULATION library fails when optimization is turned on with Os setting. With Os setting it works only once after full chip erase and fails to read (resets) after any ...
Hi everyone, I’ve been following the official ST guide for setting up USB Power Delivery (PD) Sink on an STM32 device, as outlined here: Getting started with USB-Power Delivery Sink. I successfully compiled and flashed the firmware onto my NUCLEO-G07...
Hi ,I am using STM32G4 to receive USART data from external interface and USART buffer overrun when USART interrupt conflicts with Flash Erase operation. As mentioned in STM32G4 Reference manual , in single bank mode, any read operation while writing/...
