I have a STD version CW3.1 which works fine with a evluation board (MCU-9S12E128) but does not work with my board (MCU-9SE64). The problem is that code can not be written to the flash. I tried CW4.5 which works with 9S12E64.
Someone can explain to me that why does CW3.1 work with MC9S12E128 but not work with MC9S12E64. Thanks.
