Flashing the Factory SD Image

To restore your PicoCalc SD card to its factory state, follow these steps:

Requirements:

• A microSD card (at least 16GB recommended)
• A computer with Linux/macOS/Windows
• A microSD card reader

Custom Partitioning

The PicoCalc SD card uses a dual-partition structure:

Partition	Size	Format	Purpose
/dev/sdX1	Remaining space	FAT32	Storage for PicoMite, uLisp, NES Emulator, etc.
/dev/sdX2	32MB	fuzix filesystem	Root filesystem for FUZIX

Manually Partitioning an SD Card

If you need to manually create an SD card for PicoCalc, use the provided partitioning script:

wget https://github.com/clockworkpi/PicoCalc/raw/refs/heads/master/Code/scripts/partition_usb_32mb.sh
chmod +x partition_usb_32mb.sh
sudo ./partition_usb_32mb.sh sdb

(Replace sdb with your actual SD card device.)

Notes

• The USB Type-C port is the default serial port for PicoCalc, not the Micro USB port.
• FUZIX supports a maximum 32MB root filesystem.
• Ensure you backup your data before modifying the SD card.
