Hi to all,
I have a problem with STVD7 when I try to implement ChechSum Routine (AN1070). I'm using ST7 Lite19 . Now, when the program try to loop and sum all location (flash Memory 4k from F0000h to FFFFh), when try to read location FFE0h give me a error ''Non existant memory at address 0xffeo''. Somebody know how I can resolve the issue ? Many Tanks MBKSOptions

That is because FFE0-FFE1 is an unused vector location and hence, in MCU configuration window, these locations are NEM-> Non-existent memory. This problem will not be faced on the device.
