Many users reported that the previous kk1024udbin failed to write correctly on Winbond W25Q64 and Macronix MX25L25635E flash chips. The new update includes a dynamic JEDEC ID detection routine, automatically applying chip-specific write delays and erase block sizes.

Through function inlining and dead-code elimination, the kk1024udbin updated binary is 14KB smaller yet boots 22% faster on ARM Cortex-M4 and M7 cores. This is especially beneficial for battery-powered sensors where every millisecond of wake time matters.
