Himax WEI int8 build not float32

#1

Anyone else finding out that the WEI-I only works with “int8” not “float32” settings before building the final firmware?

Here is the error message I get with float32.

@Rocksetta, the model does not fit in flash.

[ldac] "../memory.lcf",line 72: Section .data (address range=0x20069700..202023ff)

Which makes sense, given that the float32 model probably is 4x larger.
