SOFTWARE
RP2350pc can be programmed with RaspberryPi C-SDK or MicroPython SDK.
For the retro computing fans the Reload emulator written by Veselin Sladkov will support RP2350pc soon and will emulate Apple ][, Apple][e, Oric Atmos, Pravetz 82, Pravetz 8D and all games from Total Replay 5.2 are supported.
Paul Robson works on RP2350pc API which will allow compilers and OS to be created with unified API (BIOS).
Programming RP2350pc
The RP2350 firmware is UF2 file. You will be able to get pre-build firmware of reload emulator on olimex’s ftp when available.
To program the .uf2 files you need USB-A to USB-C cable like USB-CABLE-AM-USB3-C.
- Disconnect the power supply from USB-PWR1 connector and connect it to USB-PGM1 connector.
- Press the BOOT1 button and switch on the power supply with PWR_ON/OFF1 switch then release BOOT1 button.
- You will see on your computer new disk drive RPI-RP2.
- Copy the .uf2 file to this drive, once it’s copied the drive will disappear.
- Switch OFF the PWR_ON/OFF1 switch
- Disconnect the USB-C cable from USB-PGM1 and connect to USB-PWR1 connector.
- Switch ON power supply.
