Hi @mƎALLEm,I need to develop a unique serial number for one of our products that will go into production soon. I'd rather use the UID that is built into the STM32H7A3 chip but I have some questions.I understand that it is a 96bit value that I can re...
The STM32H5 use SWD port 1 for flash/debug (other old families as F4, F7, G0, G4...) uses port 0.I can compile the code for M33 with TrueSTUDIO, but I can't flash the application because I don't know how to specify the port number.I couldn't find h...
Hi,I'm currently gaining experience with the STM32G4, whose ROM bootloader supports various interfaces. AN2606 describes the configuration of the pins occupied by the interfaces.Various pins are operated in push-pull mode, which can lead to undesirab...
Hello everyone,I'm currently working with the "STM32G0B1RE" and facing an issue where my system automatically resets. The problem occurs sporadically, sometimes after a week and other times within 2 or 3 hours. Upon investigating, I found that the la...
I am trying to use tickless idle mode. But for some reason I cant go into sleepmode, the mcu instantly comes out of it. Before I implemented tickless idle mode in my main application. I disabled all interrupts but still for some reason I could not ...
We are trying to add built-in self-test capability to a program we are developing.Specifically, we would like to periodically check ROM and RAM. Are there any sample programs for those? [MCU] STM32F412VGT6
I'm using an ST-Link broken off from a NUCLEO board to program a custom board with an STM32G4A1 on it. The issue is that UART transmission only seems to work while the ST-Link is connected - probing the line with a scope shows no activity when the ST...
Hello everyoneI've hit a bit of a snag with my PCB redesign (V2) featuring an STM32F429ZIT6. While the initial version (V1) worked like a charm, some layout changes and component swaps (SN74ABT16245ADL to two SN74HCT245DWR) in V2 are causing issues w...
Hi,I need to service an external watchdog when a flash sector is being erased. The sector being erased is in the same flash bank where code is executed from. Before I try to jump and run from RAM I had a few questions.Where is flash stall discussed...
Hello,i have problem with custom board assembled with STM32F767BIT6. I'm trying to interfacing LCD-TFT DEM 800480K3 TMH-PW-N which is assembled by HX8264E, HX8664B drivers. I'm using RGB888 interface configured via STMCubeIDE filled by resolution 800...
