In our design we are using Kinetis MKL03Z8 with only 8KB of flash. We have been able to program needed application from peripheral examples on test board FRDM-KL03Z (LPUART and I2C + using VLLS modes) but firmware is to large to fit into 8KB. I also try barebone SDK (v2.3.1) minimalistic example ("demo_apps->hello_world") inside MCUExpresso, but I could not get below 9KB PROGRAM_FLASH, even with optimization level for size (-Os). How can i further reduce program size (I assume examples have some ballast) or where I get driver/example files (e.g. MWE) with smallest footprint possible for LPUART, I2C master peripheral to fit into 8KB region space?
