To install the Firestarter Python program and the firmware on the Arduino, follow the steps below:
Use the package manager pip to install Firestarter.
pip install firestarter
This command installs the Firestarter application, which allows you to interact with EPROMs using the Relatively-Universal-ROM-Programmer.
First, a few things to remember.
To install the firmware on the Arduino, use the fw command with the --install option. This command installs the latest firmware version on the Arduino.
Firestarter is using avrdude to install the firmware. avrdude is avalible as a separate installer or via Arduino IDE.
-p, --avrdude-path <path>: Full path to avrdude (optional), set if avrdude is not found.-c, --avrdude-config-path <path>: Full path to avrdude config (optional), set if avrdude version is 6.3 or not found.--port <port>: Serial port name (optional), set if the Arduino is not found.The fw --install command installs the latest firmware on the Arduino. The process typically involves the following steps:
avrdude using the --avrdude-path option if it is not found automatically.--port option.avrdude.To install the firmware on the Arduino, you can run:
firestarter fw --install
Firestarter provides several commands to interact with EPROMs using the Relatively-Universal-ROM-Programmer. Available commands: read, write, blank, erase, list, search, info, vpp, vcc, fw, config
firestarter [options] {command}
-h, --help: Show help message-v, --verbose: Enable verbose mode--version: Show the Firestarter version and exit.Reads the content from an EPROM.
firestarter read <eprom> [output_file]
<eprom>: The name of the EPROM.[output_file]: (Optional) Output file name, defaults to <EPROM_NAME>.bin.The read command reads the data from the specified EPROM and optionally saves it to a file. The process typically involves the following steps:
<EPROM_NAME>.bin.Writes a binary file to an EPROM.
firestarter write <eprom> <input_file> [options]
<eprom>: The name of the EPROM.<input_file>: Input file name.-b, --ignore-blank-check: Ignore blank check before write (and skip erase).-f, --force: Force write, even if the VPP or chip ID don't match.-a, --address <address>: Write start address in decimal or hexadecimal.The write command writes the contents of a specified binary file to the EPROM. The process typically involves the following steps:
--ignore-blank-check option.--ignore-blank-check is used.Checks if an EPROM is blank.
firestarter blank <eprom>
<eprom>: The name of the EPROM.Erases an EPROM, if supported.
firestarter erase <eprom>
<eprom>: The name of the EPROM.Lists all EPROMs in the database.
firestarter list [options]
-v, --verified: Only shows verified EPROMs.Searches for EPROMs in the database.
firestarter search <text>
<text>: Text to search for.Displays information about an EPROM.
firestarter info <eprom>
<eprom>: EPROM name.The info command retrieves and displays detailed information about the specified EPROM. This information typically includes:
Displays the VPP voltage.
firestarter vpp
Displays the VCC voltage.
firestarter vcc
Checks or installs the firmware version.
firestarter fw [options]
-i, --install: Try to install the latest firmware. (Do this without a chip in the socket or without the shield attached)-p, --avrdude-path <path>: Full path to avrdude (optional), set if avrdude is not found.--port <port>: Serial port name (optional).Handles configuration values.
firestarter config [options]
-rev, <revision>: WARNING Overrides hardware revision (0-2), only use with HW mods. -1 disables override.-r1, --r16 <resistance>: Set R16 resistance, resistor connected to VPE.-r2, --r14r15 <resistance>: Set R14/R15 resistance, resistors connected to GND.To read an EPROM named W27C512 and save the output to output.bin:
firestarter read W27C512 output.bin
To write a binary file input.bin to an EPROM named W27C512:
firestarter write W27C512 input.bin
To get information about an EPROM named W27C512:
firestarter info W27C512
This command will output detailed information about the W27C512 EPROM, showing package layout and the jumper configuration for the RURP shield.

By adding a file named database.json in the .firestarter folder under the home directory, it is possible to overide Eprom configurations or add new Eproms in the Firestarter database.
To overide an Eprom configuration extract the configuration for the inteded Eprom with the info config command, ex: firestarter info W27C512 -c and the configuration will be printed.
W27C512 config:
{
"WINBOND": [
{
"name": "W27C512",
"pin-count": 28,
"can-erase": true,
"has-chip-id": true,
"chip-id": "0x0000da08",
"pin-map": 16,
"protocol-id": "0x07",
"memory-size": "0x10000",
"type": "memory",
"voltages": {
"vpp": "12"
},
"pulse-delay": "0x0064",
"flags": "0x00000078",
"verified": true
}
]
}
To overide the pulse-delay copy the configuration into the database.json in the .firestarter folder and remove all fields that arent relevant to the change exept for the manufacturer name and the Eprom name, ex:
{
"WINBOND": [
{
"name": "W27C512",
"pulse-delay": "0x0064"
}
]
}
By adding a file named pin-maps.json in the .firestarter folder under the home directory, it is possible to overide a pin map or add new pin map that arent existing.
To overide or add a new pin map use the info config command, ex: firestarter info W27C512 -c to get a starting point.
W27C512 pin map:
{
"28": {
"16": {
"address-bus-pins": [
10, 9, 8, 7, 6, 5, 4, 3, 25, 24, 21, 23, 2, 26, 27, 1
]
}
}
}
The top level key ("28") refers to the number of pins for the Eprom and the sub-key ("16") is the pin-map in the configuration data for an Eprom.
Valid fields:
address-bus-pins is an array with the pin numbers from the Eprom pin layout, starts with least significant address pin (A0) and added in order to the most significant address pin (A0,A2,...Ax).rw-pin Optional, if a read/write or a program enable pin is pressent rw-pin must be set to the pin layout number.vpp-pin Optional, if the Eprom needs progaming voltage (Vpp) on pin 1 vpp-pin must be set to 1.Please report back new och changed configurations to Firestarter. Create an Issue where you describe the added Eprom or the changes that are done and add the json configurations from the database.json and pin-maps.json that are made.
Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
Please make sure to update tests as appropriate.
