Can it run on https://www.espressif.com/en/products/socs/esp32-c3 ?
From the website
ESP32-C3 is a single-core Wi-Fi and Bluetooth 5 (LE) microcontroller SoC, based on the open-source RISC-V architecture. It strikes the right balance of power, I/O capabilities and security, thus offering the optimal cost-effective solution for connected devices. The availability of Wi-Fi and Bluetooth 5 (LE) connectivity not only makes the device's configuration easy, but it also facilitates a variety of use-cases based on dual connectivity.
Thanks for the pointer. I take a look at the document of ESP32C3 and I feel that it is possible to port egos-2000 on it. It has enough memory and flash storage.
@yhzhang0128 thanks for the prompt reply. Just plug it in and upload the code? Any guidance would be greatly appreciated
I think it could take some time to port egos-2000 to ESP32-C3. The key is to adjust the memory regions for this processor. I could image the following needs to be done.
- Put the earth layer to the 384 KB ROM
- Put the 4MB disk image to the embedded flash
- Adjust other memory regions into the 400 KB SRAM.
In order to do this, you will need to read and modify
- All the
lds
files in this repo - The memory map defined here: https://github.com/yhzhang0128/egos-2000/blob/main/library/egos.h#L53
It is a good exercise though. I went through the exercise myself with several months when I played with the Arty board.
This is very helpful. Is there a way to test it using a ESP32-C3 emulator?
When I played with SiFive FE310, the chip company, SiFive, provides an open-sourced QEMU patch that I can use for emulation. I guess you may need to see whether the company producing ESP32-C3 provides something similar.
