Hello,I am working on custom bootloader + application setup on a STM32G070CBT6Currently, I need to store bootloader flag that indicate whether the MCU should jump to the bootloader code or to the application code.Since the movement i am reserving 1 f...
Hi,Will PC0 PC1 LPUART functions in normal operation? I have to use this LPUART in normal operation of MCU, not in power saving mode.Is there any limitation on this like speed, baud rate etc. Regards,Anurag
Good day,I am writing firmware for a custom board using the STM32G0B1KET6 and am experiencing issues related to writing a serial number to the internal flash.As far as I can tell, this MCU has 512 KB of flash split into 2 banks of 128 pages (each pag...
Hi everyone,I’m trying to generate two PWM signals with 50% duty cycle and a 90° phase shift, to simulate an A/B type output.I managed to achieve this using two different timers and adjusting the compare values, but I’d like to know if it’s possible ...
I’m running into a strange issue when trying to jump into the STM32 bootloader.I’ve built an FDCAN bootloader flasher using an STM32H7 along with a Windows host program. This setup allows me to reprogram both virgin and already-programmed. To do this...
Hello,I have a ADC clock running at 96MHz prescaler divided by 10, 12bit, Sampling time 47.5 Cycles. I am just trying to sample this DC volgtages. I have a battery that has around 20Volts, and I am stepping this voltage down using the voltage divide...
Hi,We are using the STM32H725VGH6 MCU and are plannign to use the internal SMPS for VCORE.With regards to the connections required for the VLXSMPS pin, I would just like to confirm that a 220pF capacitor is required on this pin in the "Direct SMPS Su...
I tried to set readout protection via ST-LINK CLI - it's enabled and disabled correctly, but after RDP=0 I can't erase/write chip - I've got an error on write operation. Tested on 2 boards and both boards have same behavior. e:\STM32 projects>"%PROGR...
