I am currently working with a K60 (MK60DN512VLL10) microcontroller with 100 pins and 512k flash, but I am needing for more memory. I found a possible solution K64 (MK64FN1M0VLL12) 100 pins 1Meg flash. What are the possibles problems that I will find? Currently, I am in the last prototype (no hardware modifications) and I need to put it in production for november this year. I am using several resources like DMA, SPI, I2C... MQX 4.1. several times I manually set registers.
