Hi,
I have two chips are NXP P89V51RD2BN and NXP P89V51RD2FN.
I have burned program into P89V51RD2BN in ISP mode successfully, but in the P89V51RD2FN can't successful.
I used Flash Magic(the last version) to burn my program.
In P89V51RD2FN, when I started to burn program by Flash Magic, then the "Reset the device into ISP mode now" message showed up, then i pressed reset button in my equipment tried to into ISP mode.
The message always in there, and wasn't burning the program.
I did every thing just like what I did in the successful chip (P89V51RD2BN).
And I researched the datasheet, there is only "Temperature range" different.
So could someone tell me how can I deal with this problem?
Thanks a lot
Justin
