I know it's easy to change between firmware versions, but I would prefer to have a more universal "quick test unit"...
The current firmware (ADF+HFE) take already ~90KB, the bootloader ~27KB, This is a 128KB device. So i am not sure that all will fit into the internal flash.
There is twice the flash space of the PIC18, but the ARM instructions opcodes are twice longer, and the USB Stack take a lot more than the SD Card "stack". (The SD HXC bootloader for the PIC18 take 4KB, with the FAT32 support versus 27KB for the same functionnality into the STM32).
