I am a Little confused about what file is uploaded to the Due when you use bossa or the IDE is it a .bin, .elf, .hex? Also in large scale projects how far can the RAM/CPU really carry you? And one last question, is it possible to write a small 32-64k-128kb cache to the flash memory of the board for a sketch or compiled program to access? Example: You have the board running some repetitive task, there is an error. Write error to cache in flash memory, then continue with repetitive task. Thanks in advance guys.Get my board tomorrow super excited!
