Dear, I currently use a STM32G0B1 on a custom board ans all worked fine until now. My firmware change the options bytes at running to disable the dual bank and using and single bank Flash.At the power up, the firmware check the options bytes and chan...

Dear, I'm using embedded STM32 UART bootloader to update the firmware of a slave STM32G070.For some reasons, the host should maintain the slave in reset during a long time before starting slave bootloader. Sometimes, when the slave is maintain in res...

Dear,I currently trying to used the timer in encoder mode.It seems to working fine whatever the mode configured.I useing the timer interrupt (Capture Compare) to read the number of step (Counter (CNT)).In mode 1 and mode 2, the CNT is decrement by 2 ...

Dear,I currently use a STM32G070 with external touch sensor component usuing I2C interface.This component aloow me to communicate with it only during a ready window and this window is automatically closed after a delay without communication or a I2C ...

Dear,I have a big problem on a STM32G070 and I don't know what I can do to solve it.The system is composed of 2 boards with a STM32G0B1 for the first (master board) and a STM32G070 for the second (slave board).The 2 MCUs are connected by UART and thi...

If I understand right the device marking, it's a revision A. I'm understand the possibility to lock the device if something wrong.But I used the STM32CubeProgrammer to change the options bytes value and the MCU is lock so it's really strange.

OK, I tried to force boot0 pin to to boot the the main flash but same result. I'm not able to connect to the MCU.I also tried to force the boot0 pin to boot on the system memory and same result.For me, it's a right result because the boot0 pin isn't ...

Boot0 pin is shared with SWCLK so I won't be able to use a ST-link probe to connect to the MCU (but I can do the test). And by default on STM32G0, the Boot0 pin is not used. you must change the options bytes to use the Boot0 pin as legacy mode. But I...

I change the "DUAL_BANK" bit. At running time, I changed it to used a single bank flash.Before resetting options byte, it's was as on the photo. I just enable the "DUAL_BANK" bit and after that, i'm not able to connect to the MCU. On the SWD connecto...

On page 279, there is the "Bootloader Startup timing" and on page 282, there is the "USART connection timing".In table 122, you can see the USART bootloader minimum timingIt's no specify to be for a communication at 115200 bauds but I deduce it from ...
