Re: Flashing too big??

No, 512 is KBytes...the TINI firmware goes in banks 40-46 (the file
tini400.tbin), and the application (slush400.tbin or what you are calling
your 'bootstrap' application) typically fits into bank 47.  The '-flash 40'
argument tells JavaKit that this thing has flash starting at address
400000h.  If JavaKit tries to load to something it thinks is flash, it tries
to erase the 64KB bank first.  JavaKit assumes that you only have 512KB of
flash (i.e. 8 'banks' of 64KB each)
