ESP32-C3 mininal bare-metal assembly example

Postby ivand58 » Tue May 10, 2022 7:27 am

Hi
Is there a minimal framework for bare metal in assembly language? I'd like to practice RISC-V assembly maybe with the help of the functionality that is provided in the ROM.
For IO example, a character in ```a0``` can be sent to the terminal over ```uart_tx_one_char = 0x40000068;``` , and can be received through ```uart_rx_one_char = 0x40000070;``` , is that so simple, or some initialization is required in advance ?
