# How to Create an Official PicoCalc SD Card
|
||
|
||
The purpose of this wiki is to document the partitioning and creation process of the official PicoCalc SD card.
|
||
|
||
⚠ Warning: This process involves disk partitioning and formatting, which may result in data loss if performed incorrectly. Do not proceed unless you have sufficient experience with Linux system administration.
|
||
|
||
We are not responsible for any data loss or damage caused by improper use of these instructions. Proceed at your own risk.
|
||
|
||
|
||
## Script
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
DEVICE="/dev/$1"
|
||
|
||
if [ -z "$DEVICE" ]; then
|
||
echo "No disk"
|
||
exit 1
|
||
fi
|
||
|
||
if [ ! -b "$DEVICE" ]; then
|
||
echo "$DEVICE not existed"
|
||
exit 1
|
||
fi
|
||
|
||
|
||
echo "Warn: $DEVICE will be destroyed and all data on this disk will be lost,Do you want to continue?"
|
||
read -p "Confirm？(y/n) " confirm
|
||
if [ "$confirm" != "y" ]; then
|
||
echo "Canceled"
|
||
exit 1
|
||
fi
|
||
|
||
|
||
echo "Begin partition..."
|
||
|
||
# use parted to create msdos partition table
|
||
echo "Create msdos partition table..."
|
||
parted "$DEVICE" mklabel msdos
|
||
|
||
|
||
TOTAL_SIZE=$(lsblk -bno SIZE "$DEVICE")
|
||
SIZE_MB=$(( TOTAL_SIZE / 1024 / 1024 ))
|
||
|
||
|
||
PART1_SIZE=$(( SIZE_MB - 32 ))
|
||
|
||
|
||
echo "Create first partition in size ${PART1_SIZE}MB, FAT32..."
|
||
parted "$DEVICE" mkpart primary fat32 1MiB ${PART1_SIZE}MiB
|
||
|
||
|
||
sleep 2
|
||
|
||
echo "Format first partition FAT32..."
|
||
mkfs.fat -F32 -v -I "${DEVICE}1"
|
||
|
||
|
||
echo "Create second partition in size 32MB..."
|
||
parted "$DEVICE" mkpart primary ${PART1_SIZE}MiB 100%
|
||
|
||
|
||
echo "All done："
|
||
fdisk -l "$DEVICE"
|
||
```
|
||
|
||
## How to Use the Script
|
||
|
||
- Insert a blank SD card into your computer.
|
||
- Run the script:
|
||
```bash
|
||
sudo ./partition_usb_32mb.sh sdb
|
||
```
|
||
(Replace "sdb" with the correct device name for your SD card.)
|
||
|
||
***BE CAREFUL ABOUT THIS***
|
||
***BE CAREFUL ABOUT THIS***
|
||
***BE CAREFUL ABOUT THIS***
|
||
|
||
If you are not careful, all the original data on the disk will be destroyed.
|
||
|
||
This script prepares the SD card for PicoMite, uLisp, NES emulators, and other Pico firmware using the fatfs library.
|
||
|
||
Additionally, FUZIX can use `/dev/sdb2` (32MB partition) as its root filesystem, as FUZIX supports a maximum partition size of 32MB.
|
||
|
||
## Flashing the FUZIX 32MB Image
|
||
- Download the FUZIX image:
|
||
[PicoCalc_Fuzix_v1.0.img](https://github.com/clockworkpi/PicoCalc/blob/master/Bin/PicoCalc%20SD/firmware/PicoCalc_Fuzix_v1.0.img)
|
||
|
||
- Flash the image to the second partition:
|
||
```bash
|
||
sudo dd if=filesystem.img of=/dev/sdb2
|
||
```
|
||
|
||
## Example Partition Layout
|
||
|
||
After running the script, your SD card should have the following partition structure:
|
||
|
||
```
|
||
Disk /dev/sdb: 59.48 GiB, 63864569856 bytes, 124735488 sectors
|
||
Disk model: STORAGE DEVICE
|
||
Units: sectors of 1 * 512 = 512 bytes
|
||
Sector size (logical/physical): 512 bytes / 512 bytes
|
||
I/O size (minimum/optimal): 512 bytes / 512 bytes
|
||
Disklabel type: dos
|
||
Disk identifier: 0x66a93eb2
|
||
|
||
Device Boot Start End Sectors Size Id Type
|
||
/dev/sdb1 2048 124669951 124667904 59.4G c W95 FAT32 (LBA)
|
||
/dev/sdb2 124669952 124735487 65536 32M 83 Linux
|
||
```
|
||
|
||
Now your SD card is ready for PicoCalc, FUZIX, and other supported firmware!
