woezel unzip dict size

E (51080) extmod/uzlib/tinflate: dictionary not large enough! offs=8765, dict=8192

known issue; was thinking of a hack to use the ugfx framebuffer as dictionary buffer. :-)

(ugly, but as long as you don't update your screen, it will be ok..)

other option is to find that magic zlib option to compress with a smaller dictionary.. (haven't found that option yet)

edit:

The zlib header file mentions a 'minigzip' tool which can probably compress with smaller dictinaries. Have to look at that. (maybe have to recompile zlib with lower dictionary size)

edit2:

we can build a 'minigzip' tool with the zlib source:

• download zlib source
• ./configure
• edit zconf.h (change MAX_WBITS to 13)
• make

And I think there might be some memory left on one of the heaps. We also might be able to cleanup some allocs before inflating.

edit:

There's 52 KB of memory extra, which is just not allocatable with malloc(). The only catch: every read and write should be an aligned 32 bit dword.
