Hello,Using the STM32CUBEPROGRAMMER v2.2.0 + the NUCLEO-N657X0-Q :I tried to set the OTP_124 -> HSLV_VDDIO3 bit to 1 but it did not suceed. First, I read the whole otp, put 1 in that field then press Write and it did not work, the OTP_124 stays at de...
Hi,I am using NCLEO-U385RG-Q running STM32u385. I created a project using the board selector. I configured I2C2 using STM32CubeIDE to run in fastmode at 400khz for PINs PA6/PB2 per schematics described in MB1841. My clock sources are all defaults...
I have developed software on the Nucleo-L433RC-P development board which uses the STM32L433RCT6P MCU (the P defines it has 2 x VDD12 pins for an external SMPS).However, I have designed a PCB that uses the STM32L433RCT6 (no VDD12 pins) but want to con...
Hello,I'm encountering an issue while testing the Standby Mode on my device.Most of the time, the device enters and wakes from Standby Mode successfully. However, after repeated testing, it occasionally fails to enter the mode.What could be the poten...
Hi,We are using STM32F091VCT6 in our application, however we are observing some instance of RTC losing time. We checked entire datasheet but were unable to figure out how much time the RTC takes to switch to VBAT after VDD falls below given threshold...
Hello.I'm having issues with STM32CubeMX and VScode setup. I have the STM32 VScode extension installed and all the extras that were required as per this page ( https://marketplace.visualstudio.com/items?itemName=bmd.stm32-for-vscode ). I generate a m...
Hello, I have a problem with a PCB with an STM32F410. This board is used in the field, and in some cases, it freezes, and only works by reflashing the firmware. We're using some data in the Flash (emulated EEPROM) to write data, about 18 bytes, writt...
Hello,I am using STM32H7 as SPI slave with DMA transfer, the communication works fine till 18MHz of clock frequency from the master side however for higher clock speeds of 20 MHz - 31MHz it is noted that the bit shifts by 1 bit for the whole stream o...
Hi all,I am working on a QSPI driver for W25Q512 flash memory (extloader for stm32cubeprogrammer and main firmware driver). I had a look at the errata ES0392 - Rev 13 and I have a question about paragraph 2.8.4: 2.8.4 - QUADSPI internal timing critic...
Hello,I am working with the STM32G0B1CCT6 MCU and facing an issue while flashing firmware using ST-LINK.During the flashing process, I get the following error:Error: Sector erase operation has failed at least for one of the existing specified sector...
