Our customer attempted to update the firmware on their device which uses an STM32L433CC. Programming failed to erase and download the firmware on the device. STM32CubeProgrammer 1.4.0 succeeded in programming the device.Customer is using a Windows 11...

I have just updated a board design, replacing the STM32L433CC with an STM32L4P5RE. I have no problems using the RNG on the L433. However, with the L4P5, I get only one result from the RNG before it give a seed error.RNG: CR = 00800004, DR = 9a4c8249,...

Trying to port my code to CMSIS-RTOS v2 and running into some missing functionality. I don't see an osThreadSuspendAll() replacement.

My build fails with the error shown below. I get this with the default toolchain and with GCC 10.2.I am using STM32CubeIDE 1.6.1 downloaded today, installed via RPM on Fedora 33, with L4 V1.17.0 firmware.Any sort of fix or work-around would be helpf...

Currently the STM32_L4 HAL provides HAL_UART_DMAPause and HAL_UART_DMAResume. These pause/resume both TX and RX on the UART.I am using DMA for both transmit and receive on a UART. I have a case where I need to pause the receive (for flow control) ...

I hit the same issue when upgrading from L4 HAL from 1.17.1 to 1.17.2.Reverting stm32l4xx_hal_timebase_tim.c to the version from 1.17.1 fixed it for me.Update: More in-depth debugging revealed that the root cause of the issues was that I was calling ...

Has this issue been replicated by the development and QA teams? When can we expect to see it fixed?

This also affects STM32L4+ chips. STM32CubeProgrammer exhibits the same issue when programming the STM32L4Q5RE via USB DFU.

I just ran into this issue and I thought I would leave an answer which explains what is happening for anyone else experiencing this issue and how to avoid it. FreeRTOS raises the NVIC base priority as soon as any FreeRTOS function (such as osThreadCr...

There is an even worse problem lurking here. HAL_PCDEx_BCD_VBUSDetect() calls HAL_Delay() from within an interrupt context. This causes any interrupt that has a lower priority than the GPIO interrupt to not get called while BCD is running.Please pr...

STM32CubeProgrammer 2.16.0 fails to program STM32L433CC via USB

Why am I getting an RNG failure on the STM32L4P5?

What is the CMSIS-RTOS v2 replacement for osThreadSuspendAll()?

What is causing this build failure with STM32CubeIDE on Linux with FW_L4 V1.17.0?

Feature Request: HAL_UART_DMAPauseReceive, HAL_UART_DMAPauseTransmit
