Khadas Tone 2 Pro MCU and XMOS Firmware V1.2 Upgrade
Khadas has released its latest V1.2 XMOS firmware update along with its new MCU firmware for the advanced Tone 2 Pro DAC system. You should update if you have Tone 2 Pro from the first or second batch, serial number of these batches start with either 0C or 11. These two upgrades(V1.2XMOS and MCU) when used in combination will fix several issues such as the audio filters, and high noise-floor with 44.1kHz and 48kHz respectively. Newer batches that are available with us now are already upgraded with these and don’t need to proceed with this process.
