Real size of flash memory
Posted: 06 Dec 2017 12:56
Dear all,
according to specifications the Z-uno module possess 28K (28672 bytes) of flash memory for sketches. In Arduino IDE, it allows code up to 32K. How can this be?
Furthermore, my program reached about 98% of the 32K. When I try to flash it, the flash procedure completes successfully, but on the Z-uno still runs the old sketch (a simple blink-blink sketch). I managed to downsize my program to about 91% of the allowed 32K in Arduino IDE (29376 bytes), now it flashes and run successfully.
So somehow, something is not right regarding the flash size. For sure it is not 32K but also it is larger than 28K. Could you please elaborate more on this?
Thanks
