=== Cartridge selector ===
[[File:C4CPC CprSelect.png|right|384px]]
CprSelect is a special cartridge that allows browsing the SD cart for cartridges to load.
The main area displays the content current foldercontents. Browsing is done using either one of the joysticks or the keyboard.* Keyboard controls : cursors for browsing, space/enter/copy to select and esc to return to parent folder* Joystick controls : left/right/up/down for browsing, fire 1 to select, fire 2 to return to parent folder
Left/Right jump from page to page if the folder cannot be displayed in one screen.
=== SD card preparation ===
The C4Cpc C4CPC is delivered with a prepared microSD card which contains the Basic Cartridge in slot 0 and the cartridge selector in slot 15.
Using your computer, cartridge images can be added to any slots or cartridge selector by writing to the SD card.
* _C4CPC : This is the main folder that contains the dip switch selectable folder.
* _C4CPC/0 to _C4CPC/F folders, which should contain only one valid CPR/BIN file. The cartridge emulator will first look for a CPR then a BIN file and load it to the cartridge.
SD original content can be found in [[File:C4CpcSdContent base.zip]]
=== How it works ===
At power up, CPC/USB whichever is the first, the uC will check for a valid .CPR/.BIN file to loadin the DIP switch selected slot.
* If the file is smaller than 160KB, it will be loaded directly
* If no file is available or the file is bigger than 160KB, a bootloader is 1st loaded. The bootloader will then load the cart file if any.
Note that C4CPC is powered either by the CPC or /and the USB port. That mean means that power cycling the CPC will NOT initiate a new cart loading if the cart is also powered by USB.
=== From SD card ===Just select your cartridge slot and power your CPC === From Cart loading from USB ===
A connected cart should appear as a serial port (COMx on windows, /dev/ttyACMx on linux, /dev/tty.modemxxxx on OSX).
Windows require a .inf file to install the proper drivers.
Loading is done using a python3 script which has the following syntax :
<code>C4CpcCom.py -p port -c cart.cpr</code>
where port is the serial port assigned to the cart.
Example for linux:
<code>sudo python3 C4CpcCom.py -p /dev/ttyACM0 cart.cpr</code>
Latest version available in [[File:C4CpcCom.zip]] will only work with FW V1.00.01 and upward
== Firmware upgrade ==
C4CPC microcontroller firmware is user upgradable through the USB port and requires the following tools and drivers :* dfu-programmer for updating the code* driver : provided with dfu-programmer windows version, native support on recent linux and OSx A [http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/c4cpc-fw-update/ dedicated forum thread] exists for new firmware announcement support and discussion.=== Windows Update requirement ===Update procedure requires the dfu-programmer software: * Executable version is provided for windows users.* Linux users should find it in they distribution repository or build it from source. Older versions (before 0.7) of dfu-programmer have different commands so they will fail to run the UpdateCartEmu.sh script correctly. It is highly recommended you download the source and build it. * OSX users will have to build it from provided source and script in dfu-programmer_install_OSX. Check the included readme.txt for detail. === Upgrade procedure ===Start C4CPC in usb update mode* put dip switch 4 ON (other three switches to OFF)* connect the card in one USB port* press and release the C4CPC reset switch Install DFU driver (Windows only)*After the reset, windows will look for the device drivers. These are located in the windows\dfu-prog-usb-1.2.2 folder You now just need to run the update script :* Linux /OSx, you need to have root/admin right<code>sudo UpdateCartEmu.sh</code>* Windows, from the update package windows folder<code>UpdateCartEmu.bat</code> A successful update looks like this : Manufacturer Code: 0x58 (88) --- Erase --- Erasing flash...
