I have recently received a Duinomite eMega from yourselves.
I have forked the GPL3 source code and got sound working as it would not work previously. I need to check that I2C and GPIO I/O works.
I have also ported the latest version of MMBasic to the device but obviously the licence of the software prohibits my redistributing it.
I have a question: Is the source code for the boot loader available for this device?
Sure, you can get it from here:
ftp://staging.olimex.com/Lub-clients/MPIDE%20PIC32MX7xx_bootloaders_source_project.zip
I think it is based on this (or at least old version of it):
