Anyone have en.stsw-link007_V2-33~en.stsw-link007_V2-35?

Hi :Does anyone have en.stsw-link007_V2-33~en.stsw-link007_V2-35?For some reason, I need old stlink firmware.

STM32G0 Concurrency Question

I have some data that is accessed from a normal context and also from an IRQ. I am disabling the interrupt to prevent interrupted access. So no concerns there. However, what about forcing both the normal context and the interrupt context to have the ...

Reading from Flash memory crashes the uC

HiWe are facing problems when reading a data that is written to the flash using the following function?Every time we write in reading the data the micro-controller crashes. Even if I want to see the content of the flash in that particular address usi...

My STM32 locks up when I try to access a memory mapped external RAM. Cannot be reprogrammed.

I have a custom PCB with a STM32H7A3ZI MCU, and a S27KL0642S27KS0642 Hyperbus RAM.My code, as well as the app note (AN5050) I'm following sets up the RAM for memory mapped access.I've checked and rechecked the pinout and configuration, but every time...

STM32U575 flash write often fails due to OPTWERR but I'm not writing the option bytes.

The memory I'm writing is 16-byte aligned (both flash destination and RAM source) and a multiple of 16 bytes in length. Using HAL to write the flash. Writing the first quadword fails with the error OPTWERR. This is quite unexpected since I am not, as...

Resolved! RTC resets or stalls even with backup battery

I have an application running on STM32G491 which uses the RTC. There is an external 32768Hz crystal and a backup coin cell battery (I have checked that it is not depleted: 3.12V). There are two issues:Scenario #1: I pull the main battery, wait a bit,...

Resolved! Is STM32H7Rxx/7Sxx affected by OTG_HS "transmit FIFO corrupted" erratum?

Other chips have the erratum "Transmit data FIFO is corrupted when a write sequence to the FIFO is interrupted with accesses to certain OTG_HS registers" (eg ES0392 2.25.2 for STM32H743). It isn't listed in the ES0596 rev5 errata for STM32H7Rxx/7Sxx ...

STM32 Development Boards with Replaceable MCU (Socket-Based)

Hello ST support,As a customer working on a project using STM32, I am looking for STM32 development or evaluation boards that feature a socket-based MCU instead of a soldered one. This allows for easy replacement of the microcontroller during the use...

Resolved! Having Problems activating SysTick after Stop mode

I'm using STM32F070CBT at 8mhz with almost all pins active (used for GPIOs, PWM, SPI,I2C,etc) , i'm using a timer to enter stop mode with low power regulator and waking up using GPIO external event, after waking up i checked that PWMs and GPIOs are s...

GPDMA Linked List Circular Buffering: Correct Transfer Event Mode?

I want to capture images larger than 0xFFFF via DCMI using double buffering with two GPDMA1 linked list nodes. As guidance, I'm following the DCMI_ContinuousCap_EmbeddedSynchMode example. However, it seems that the DCMI_DMAXferCplt function is writte...
