Hello Everybody !
I really need quick help regarding programming of P89V51RD2BN.
Let me explain the issue.
I have had a ready hardware for a project with P89V51RD2FN MCU of NXP.
Obviously COM is connected via MAX232.
I am successfully able to flash P89V51RD2FN with that hardware. It is running my program properly.
So this means, hardware is perfect.
Now, I have got two of the P89V51RD2BN chips.
I need to flash the same program in them.
So I removed the P89V51RD2FN from the hardware and put in the BN chip.
And then Flash Magic just keeps saying Rest the hardware into ISP mode.
I tried lots of things from forum, but no luck so far.
As I am able to flash FN chip with no issues at all, I am sure that hardware and Flash Magic is configured properly.
I also tried with another BN chip I have, no luck.
Is there any issue with the BN chips ?
Are they faulty something ?
I am attaching a photo of BN chips I have, may be helpful.
Flash Magic Version is 5.74
Please help me asap. I need to submit this project by Monday
.
Thanks a lot.
