Hi,every one!
I have been useing P89LV51RD2 for a long time.But recently i met a difficult, which is the ISP broken down suddenly after i modified my program to add another function to it.The promotion information is can't communiction ,ask me change the baud rate, i acted follow it ,but it didn't work.And then , i chaged a new chip , the question go back once more.
I met the same question a month ago, after i download a new vision of FlashMgic, i resolved it .Now, it came back again, what i coud do?
Before post this topic , i read the Andy Ayre's "Read First Before Posting ",but not work,I guess maybe the bootloader broken down,but ,why did it down? because of my program?If yes, what program would act like this?
