I followed the instructions in README, and I got no any message in OpenOCD Console from STM32.

Issue resolved! The problem hiding in memory.x linker settings. For STM32C6T6A You need set RAM to 10K instead of 20K.

Here a fixed memory.x file for STM32C6T6:

MEMORY
{
  FLASH : ORIGIN = 0x08000000, LENGTH = 32K
  RAM : ORIGIN = 0x20000000, LENGTH = 10K
}
