Hello everyone,We are experiencing an issue with a product that integrates an STM32H562ZG microcontroller.Our development environment consists of IAR Embedded Workbench 9.70.1, with the project configured using CMake.Currently, we are observing unexp...
Hello! I need help. STM32L073RZT6 MCU.How can I write, for example, 2 times 8 Bytes into any second half-page of flash memory?Every first page is recorded successfully and read successfully. For example, I write 8 Bytes of data to the beginning of th...
Both in the manual and in CubeMX, it is shown that my microcontroller, has the ability to configure the FMC, for an asynchronous muxed PSRAM interface.However, in the manual I can only find the timing description for the asynchronous NOR Flash and fo...
Hi.I am trying to test out a fault handler for our STM32G (right now, the fault handler just tries to determine the location of the code that caused the fault).If I force a fault (divide by zero) in "normal" non-interrupt handler code, I can easily r...
I am experiencing an issue when trying to use STOP3 mode on an STM32U575VIT6Q device mounted on a custom PCB. In fact, the MCU never seems to actually enter STOP3, even though I explicitly call:HAL_SuspendTick(); HAL_PWREx_EnterSTOP3Mode(PWR_STOPENTR...
In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...
I am using STM32G071RBT6. I am trying to implement encoder mode + output compare mode using same timer. Right now initially I get OC interrupt even when Tim_CCR3IF flag is 0 and once it get set it remains as it is. - Should I combine encoder and OC m...
We are using the STM32U5 MCU and its internal RTC in our project.We are facing an issue where the RTC time sometimes goes beyond 24 hours — for example, we observed a timestamp showing 37 hours. The RTC is configured in 24-hour format, and we have in...
Hi, I’m trying to better understand how the USB PMA and BTABLE work on the STM32F103. After reading the reference manual, I’m still unsure how the descriptor table size relates to the number of endpoints.I have two possible interpretations of how the...
