HOWTO

How to connect to the board

Windows, using Putty / Kitty

1. Connect the board to the UART usb-c port

2. open a serial communication

   • COM8 (check with Device Manager)
   • 921600 bauds

3. Type space then login as root (no password)

Using Minicom over WSL2

1. Connect the board to the UART usb-c port

sudo apt-get install minicom
sudo minicom -s

Configure:

• port to ttyUSB0
• speed to 921600

MISSING: over params to avoid weird characters

How to restart / stop / start zest from the board

Connect to the board then:

/root/zestboot restart
/root/zestboot start
/root/zestboot stop

How to create an ASCI HD image using linux and Hatari tools

wget https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/hatari/2.4.1+dfsg-2/hatari_2.4.1+dfsg.orig.tar.xz
tar -xvf hatari_2.4.1+dfsg.orig.tar.xz
cd hatari-2.4.1/tools
./atari-hd-image.sh 40

1) Create DOS Master Boot Record / partition table...
CHS:   0,  0,  2 @ $1bf
CHS: 159, 15, 32 @ $1c3
CHS: 160,  0,  1 @ $1cf
CHS: 160,  0,  1 @ $1d3
CHS: 160,  0,  1 @ $1df

2) Create an Atari TOS compatible DOS partition...
Sectors: 81920, sectors/track: 32, clusters: 40960
Doubling sector size as >32765 clusters -> 20480 clusters
mkdosfs -A -F 16 -n DOS -C hd.img.part 40960
mkfs.fat 4.2 (2021-01-31)
Warning: More than 32765 sector need TOS 1.04 or higher.

3) Copy the partition to disk image...
dd if=hd.img.part of=hd.img bs=512 seek=1 count=81920
81920+0 records in
81920+0 records out
41943040 bytes (42 MB, 40 MiB) copied, 0.102019 s, 411 MB/s

4) Cleaning up...
rm -f hd.img.part
Done.

How to transfer a file to the sdcard

Using WSL2 and usbipd

In an admin powershell

winget install usbipd
usbipd list

Connected:
BUSID  VID:PID    DEVICE                                                        STATE
1-1    1a86:7523  USB-SERIAL CH340 (COM8)                                       Not shared

usbipd bind -b 1-1
usbipd attach --wsl --busid=1-1

In WSL2

Note: minicon should be installed and configured.

sudo apt install linux-tools-generic hwdata
sudo update-alternatives --install /usr/local/bin/usbip usbip $(command -v ls /usr/lib/linux-tools/*/usbip | tail -n1) 20

sudo usbip port
Imported USB devices
====================
Port 00: <Port in Use> at Full Speed(12Mbps)
       QinHeng Electronics : CH340 serial converter (1a86:7523)
       1-1 -> usbip://172.25.144.1:3240/1-1
           -> remote bus/dev 001/001

sudo minicom 

Send file over z-modem

open the minicom session, go to /sdcard/
type CTRL+a S then select file to send

If you need to connect from Windows, unbind the device from wsl2:

usbipd unbind -b 1-1

How to mount the HD image on /mnt/C

cd /sdcard
/root/zestboot stop
mkdir /mnt/C
mount -oloop,offset=1024 -tmsdos hd40.img /mnt/C

Then do whatever you like in /mnt/C

Unmount the hard drive:

umount /mnt/C
/root/zestboot start
