A collection of all available firmware for PiStorm
PiStorm Firmware
This is a bundle of all current, original, and experimental/test PiStorm firmwares. Just run the relevant flash command to flash the required firmware.
UPDATE - OpenOCD is no longer required. We now have a dedicated PiStorm flash tool
Instructions
Prerequisites
- An SD card containing PiOS Lite (available here).
- Either a keyboard and screen connected to the Pi, or WiFi and SSH enabled in PiOS and a tool to access it (for example PuTTY or KiTTY).
Boot the Pi from the SD card containing PiOS Lite, and login to the Pi when prompted.
Clone the repository:
git clone https://github.com/LemaruX/PiStorm-Firmware
CD into the PiStorm-Firmware directory:
cd PiStorm-Firmware
You can now run the required firmware update with with the relevant command listed below, this will automatically detect your CPLD version and flash appropriately. (Do not use sudo to run the flash scripts).
If successful "CPLD flashed successfully!" will be displayed. If it failed to flash the CPLD then an error message or "Could not detect CPLD." will be displayed.
Included Firmware
| Command | Description |
|---|---|
| ./flash.sh | Current experimental firmware for both MaxII and MaxV CPLDs. |
| ./flash_experimental.sh | Same as ./flash.sh above, but includes support for optional C1/C3 clock calculation for PiStorm2k. ONLY for MaxII CPLDs |
| ./flash_original.sh | This is the original firmware for MaxII CPLDs that was previously available before the experimental firmware became the standard. |
| ./flash_long_hold.sh | Long hold version of the original firmware. (Has longer AS, Data and Address hold times). |
| ./flash_longer_hold.sh | Longer hold version of the original firmware. (Has even longer AS, Data and Address hold times). ONLY available for the EPM240. |
| ./flash_long_data.sh | Test firmware which only extends Data hold time. Also includes a counter which forces the 68k bus statemachine to maintain the typical 4-cycle access scheme of a real 68k. |
| ./flash_PiStormX_Basic.sh | Port of the experimental PiStormX firmware for MaxII CPLDs. ONLY available for the EPM240. |
| ./flash_PiStormX_skip_s5s6.sh | Port of the experimental PiStormX firmware for MaxII CPLDs that skips s5 and s6 states when not in peripheral bus cycle. ONLY available for the EPM240. |
