STM32F407 Option Byte 0xFF, bricked chip
Hi fellows,I have a custom board with STM32F407VGT6. The board was able to be programmed via the JTAG (4 wire JTAG interface; Boot pin is pulled low to ground and reset is connected to the JTAG interface (Nrset pin)) with a segger programmer - multip...
STM32G051 as SPI receive-only slave is not receiving data
I have a custom board with an STM32G051. The STM32 is a SPI receive only device. PA1 is SCLK, PA2 is MOSI, PB0 is nSS (which is hardware controlled). The beginnings of the project where created with CubeMX so the clocks should all be set correctly...
STM32U575 – Unable to Enter STOP3 Mode: WFI Ignored after BOR
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...
Resolved!"bricked" STM32C011J6: SWCLK/SWDIO/nRST reconfigured to GPIO - how to recover?
Owing to a developer (me) firmware blunder, I successfully "bricked" several STM32C011J6 (SO8 package) devices so that I cannot access them using STM32CubeProgrammer and STLINK.My error was this - my firmware reconfigured pins 7 (SWDIO) and 8 (SWCLK)...
STM32L073 NOTZEROERR when writing to Flash
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...
LCD DE and HV mode
hi i have been working to intergrate a parallel RGB dispay with stm32h7v3zit6 with the help of LTDC . and pretty much made it working the display has this configuration . this one worked pretty well with the stm LTDC and then i bought a new displa...
Missing FMC description in H5 Reference manual
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...
32F417: Mapping SPI1 to the SWD debug pins PB3-PB5 - how can this work?
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
STM32H533CET6 ADC Reading
I am encountering an issue with ADC readings on a custom board based on the STM32H533CET6.Hardware Setup: I have a simple analog filter connected to the ADC input. I have verified the input signal with a multimeter, and it correctly varies from 0V to...
RCC_CR.HSEBYP not reset by Software Reset
Experimenting with STM32F427 and STM32F446 I found out, that the RCC_CR.HSEBYP bit is *not* reset by Software reset. It is reset only by NRST and Power-On reset.While applications where this could lead to problems (i.e. where HSE clock source is chan...
