I keep getting warnings when using STM32CubeProgrammer_CLI that usb devices are still referenced: libusb: warning [libusb_exit] device x.x still referenced. This is a bit annoying.-------------------------------------------------------------------STM...

This is more of a notice than a question.I just spend the past week looking into an issue we had with reads from an I2C connected EEPROM. We noticed that our system started hanging after some time; sometimes after over 5h.After a lot of searching we ...

Hi,I tried to install STM32CubeProgrammer v2.10.0 on my Kubuntu 20.04.4.The error I get is CubeProgrammer_API or one of its dependencies is missing.What I could find from the forum is that could mean the installer used a different Java/OpenJDK versio...

I'm trying to create a loader for external flash. I cannot use IAR EWARM and the only examples I find use that. (e.g. https://github.com/STMicroelectronics/stm32-external-loader)I need this to work with GCC from a make file using LD linker scripts.An...

I wanted to connect to my STM32 MCU with STM32CubeProgrammer but forgot to power on the board. The programmers (I had 2 boards with 2 STLINK-v3MINIs connected) were detected but when I connected to one, STM32CubeProgrammer crashed. When powered every...

Hello,It's been a while. For now we resolved to using the older drivers but that's not sustainable.Here are the register contents of hi2c5 (which also contains the registers of hdma_i2c5_rx and hdma_i2c5_tx). Structure is `field name<tab>data type<ta...

Hi,Sorry for the late reply. I2C5 uses DMA1 Streams 2 and 3 which have a Pre-emption Priority of 5. The Pre-emption priority of I2C5 event and error interrupts are 10. If a lower number is higher priority, than as you say, DMA has higher priority.I'm...

I don't intend to spend too much time with this, at least for now but that's a good advice. Thank you.

Yeah, I probably should have included at least that bit of info :p We use the memory call with DMA: HAL_I2C_Mem_Read_DMA.The EEPROM reads and writes are all called from the same FreeRTOS task.A read is as follows:// Read HAL_StatusTypeDef st = HAL_I2...

Hi Matheus,Have you been able to solve your issue?I don't have the same problem but for posterity's sake I'm interested in what caused the issue and how you solved it.Regards, Arno

Lockup in I2C driver with STM32Cube_FW_H7_V1.11.0

STM32CubeProgrammer 2.10.0 does not work on Linux

Where can I find a working example of an STLDR that uses a GNU LD linker script?
