I see there are now firmware updates posted for the Tone 2.
What method should I use with mine as it was one of the 1st units shipped?
Check the User Manual or YouTube Guide for the instructions.
And we will release a new video soon to guide you how to upgrade the MCU for the early birds with SN 0Cxxxx and 11xxxx.
Have fun!
Hello @Gouwa can we apply the firmware Tone2_Pro_Firmware_V1.20_210408 without the MCU?
Thanks Gouwa, is there a document showing the changes made in this update?
Hi @Gouwa ,
I understand that we will have to follow a special process to update the MCU for these first two batches using the special adapter, but can we already update the XMOS firmware via USB ?
Also, I already have a ST-LINK/V2 if it’s needed for the MCU firmware
Yes, can.
Sure thing, will done while the video is ready recently.
Thanks, did the XMOS update. Will wait now for the MCU one, I have the STLink ready 
Yup. Same here. Hoping this will be a project for this weekend. Not looking forward to peeling back the rubber foot, but it will be nice to see how it measures after the MCU update. ![]()
Hi Gouwa, on the same subject, is it possible to go back to a previous version of the firmware, should the need arise?
Yes, for XMOS firmware can.
