Cornflakes Firmware v. 1.1
Follow these steps to update the firmware. (Updated July 2022)
NB: Do not follow the instructions, printed or digital, prior to this version!*
- Download the new firmware and transfer it to a SD-card.
- Power down the module/system.
- Insert the SD-card with firmware into the module.
- Press and hold the record button while powering on the module to enter Bootloader mode. The module will boot instantly and the record button can be released. The record LED will be lit, to indicate bootloader mode.

*Firmware updating is at the risk of the end user. Incorrect button combinations during boot-up can lead to errors and could leave the module in need of factory recalibration. Such repairs and recalibrations is not covered by Miso ApS and is only performed at the expense of the end user.
Changes in this version:
- (FIX) Quantize button was not properly debounced.
- (FIX) At startup the right channel of the internal buffer was filled with random numbers causing noise to be played when pressing play.
- (FIX) Wave files saved to sd card had an error in the header causing the file length to be misinterpreted when opened on a computer.
- (FIX) When the internal buffer was completetely filled with audio (~42 seconds) some setting of the parameters could make Cornflakes crash.
- (FIX) When the internal buffer was completetely filled with audio (~42 seconds) position and length parameters was not covering the full length of the buffer.
- (FIX) Error in loading of scala files causing tunings to be corrupted.
- (FIX) Wave file headers was not properly parsed so loading wave files generated by some audio software caused a crash.
