Hello,I'm trying to write runtime data in flash without disrupting code execution.I'm using a STM32G0xx, on a custom PCB with a custom bootloader. STM32 is communicating as I2C slave with another device.I have no problem erasing and writing the flash...

Hello, this will be a rather advanced problem that I'll be presenting so please bear with me until the end.I'm currently working on I2C communication, with a configuration where I have a controller that initialize 4 STM32g0 on custom PCBs.TL;DR : I w...

Hello, I'm currently working on an STM32G031G8U on a custom PCB. I can't really debug the code as I don't have access to ST-Link or SWDIO/SWCLK pins.I haven't managed to set TIM1 internal clock to 128 MHz as stated in the reference manual (section 5....

The IRQ doesn't call any functions in FLASH. It checks which I2C flag has been raised by the IRQ and then calls a callback function attached at initialization (the callback function is in RAM). By this point, the flag should have already been cleared...

Oh okay, I feel kinda embarrassed for not having noticed this valuable piece of information earlier.Thanks a lot !

So I've been digging on this problem and here's what's new : Communication from the DMA point of view is incomplete. I have 32 bytes to transmits, but for the target device that failed transmission the DMA CNTDR (counter register) value is 22, meanin...

I was able to configure the desired TIM1 at 128 MHz as needed. The process would go into fault because in the code I posted, I was trying modify PLL coefficient values without making sure that the system clock wasn't using the PLLCLK as input.Switchi...

Thank you for the hints.I don't think power supply is an issue here as the PCB is supplied with a DC supply and is currently used to drive loads such as motors without issues. I wish I could get my hand on a Nucleo/Disco board with a G0 but unfortuna...

Why does I2C address flag clear fails during flash write STM32G0 ?

[STM32g0] Multiple I2C target transmitters transmitting data in the same I2C transfer

How do you set STM32G031 advanced timer TIM1 clock source at the 128 MHz maximum frequency ?
