# X65
Modern 8-bit microcomputer
X65 is an effort to build an 8-bit microcomputer for the modern era. It uses best of breed components and strives to keep 8-bit feeling, while being usable for daily basis computing activities.
## Dev Setup
This is only for building the RP2350 software.
For writing 65816 CPU software, see [rp6502-vscode](https://github.com/picocomputer/rp6502-vscode).
Install the C/C++ toolchain for the Raspberry Pi Pico.
For more information, read [Getting started with the Raspberry Pi Pico](https://rptl.io/pico-get-started).
```
sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential gdb-multiarch
```
```
sudo dnf install cmake gcc-arm-linux-gnu arm-none-eabi-newlib gcc-c++-arm-linux-gnu
```
All dependencies are submodules. The following will download the correct version of all SDKs.
It will take an extremely long time to recurse the project, so do this instead:
```
git submodule update --init
```
To debug Pico RIA or Pico VPU code, you need a Debug Probe or a Pi Pico as a Picoprobe.
The Pi Pico VSCode Extension will need this additional software:
```
sudo apt install build-essential gdb-multiarch pkg-config libftdi1-dev libhidapi-hidraw0
```
Create `/etc/udev/rules.d/99-pico.rules` with:
```
#Raspberry Pi Foundation
SUBSYSTEM=="usb", ATTRS{idVendor}=="2e8a", MODE="0666"
```
Debug terminal:
```
openocd -f interface/cmsis-dap.cfg -c "adapter speed 5000" -f target/rp2350.cfg -c "program build/src/rp816.elf verify reset exit"
```
Console terminal:
```
picocom -b 115200 /dev/ttyACM0
```
WSL (Windows Subsystem for Linux) can forward the Picoprobe to Linux:
```
PS> winget install usbipd
PS> usbipd list
PS> usbipd wsl attach --busid 7-4
```
WSL needs udev started. Create `/etc/wsl.conf` with:
```
[boot]
command="service udev start"
```
VSCode Serial Monitor doesn't yet send breaks or let you slow down a paste. Minicom is still useful\.
```
$ minicom -c on -b 115200 -o -D /dev/ttyACM0
```
