v6.2 – toaster pronunciation, smaller firmware

I had a lot of fun playing with this robot, but this one (v5+) is hands down the best mod yet. I have the robot on my table turned on non-stop, and to have something that is actually reminiscent of a living Talkie Toaster from Red Dwarf in such an elegant (and eloquent manner) is an absolute blast! Do try it!

• The 1,015 toaster lines were run through the robot's speech synthesizer on a computer, word by word, and about fifty now sound right: Maillard, Nichrome, bruschetta, ciabatta, challah, Worcestershire, "wouldn't" and friends, and verbs it used to read as nouns ("to present the toast", "you cannot refuse"). What the controller shows is unchanged.
• The firmware is 207 KB smaller (no assert messages or debug logs, which were never shown), so about 219 KB of the app partition are free for what comes next.
• Robot only – works with the controller mod v6, nothing changed there.

Download

No ESP-IDF needed – only Python and pip install esptool. Step-by-step: Flash without building.

• ButterBot-OVERKLOKING-v6.2-robot-full.bin – one file, flash at 0x0. Simplest, but erases saved settings, owner face and IR codes.
• ButterBot-OVERKLOKING-v6.2-robot-parts.zip – keeps settings; flash with @flash_args, instructions in FLASH.txt.
• SHA256SUMS-robot.txt – checksums.

⚠️ Flash with --after no_reset and reset over USB – --after hard_reset (esptool default) can leave the robot stuck.
Upgrading from v4.x, v5.x or v6.x: only the app changed, so flashing it alone at 0x10000 is enough.
