I'm trying to setup an USART for a very small MCU of the STM32G0 family, the MCU it's theoretically being programmed, but the USART is not responding, I configured the MCU just like I did in other projects (of bigger MCUs), I'm not able to find what ...

I've have a custom board with a STM32G031,from the board we have access to the following MCU pins:+3V3_BTNRSTBTSWDIOSWCLK_USARTTXI've connected this 4 pins to a ST-LINK/V2. Like this (left) mcu, (right) st-link.+3V3_BT --> VCCNRSTBT --> NRSTSWDIO -->...

In CubeMX I'm working with STM32G031J6Mx SO8N. I think that both chips are mostly the same.

Now that you said it...yeah, that's weird, There's nothing you're missing, I don't have a TTL-to-RS232 shifter.I'm taking a look at it, everything is really weird. I managed to receive signals if I sent messages very quickly and it's very inconsisten...

Ok, this is really stupid.I managed to get a consistent (wrong) message using DMA. If I use my hands as a "resistance" between both Tx wires, I receive the correct messages.I guess that I'm stuck now working as a wire for the rest of my life.

yeah, that's for sure

Yes, baud rate is set correctly. I haven't managed to make it work with the DMA (as I want). But the following code is working right now:void send_uart_data(const uint8_t *data, uint32_t size) { for (uint32_t i = 0; i < size; i++) { while...
