Retrohacked Posted December 12, 2021 Share Posted December 12, 2021 Added Support for the new Raspberry Pi Zero 2 W. You must update config.txt, otherwise the Zero 2 W will boot the 32-bit Raspberry Pi 2 kernel, which will result in lower performance. This model requires new boot firmware and Wi-Fi firmware - make sure you update bootcode.bin, fixup*.dat, start*.elf, and the contents of the firmware directory. PWM audio is available on GPIO pins 12/13 for this model. Experimental embedded FTP server for performing updates/config changes without replacing the SD card (new configuration file options). This FTP server is a very basic implementation which DOES NOT feature any kind of transport layer security/encryption. Therefore, you should NOT enable this feature on a public network or expose the Raspberry Pi to the Internet. The FTP server is disabled by default. Support for Yamaha MU-series SysEx text messages, and bitmap messages when using a graphical display. Changed Update to circle-stdlib v15.10/Circle Step 44.3. Update ARM toolchains to 10.3-2021.07. Update to libmt32emu v2.5.3. Update to FluidSynth v2.2.4. The default FluidSynth polyphony value has been reduced from 256 to 200 to account for the lower out-of-the-box performance of the Pi Zero 2 W. For the vast majority of use cases, this will have no noticable difference. If you prefer, a +200MHz overclock can be applied to the Zero 2 W match the performance of the Raspberry Pi 3B (1.2GHz), in which case you can use the original higher polyphony value of 256. Commented-out example of how to do this is now provided in config.txt. Heatsink/cooling recommended to ensure stability if you decide to do the above. Fixed "WiFi disconnected!" would be shown on the LCD when Ethernet was disconnected. The SoundFont loading "spinner" was broken since v0.10.0.
