Anybody can help me? I found one chip can't work after download S19 files, but others are work well. I found the voltage about the BKGD was low always ,when I check the BKGD pin ,The chip's name is 9S08DZ60 64PIN
Are you using any NXP evaluation boar or you are using your own design? can you check that there is not any manufacturing issue? you are able to program the part?
only one unit is the problem?
Thanks for your help. I am using our's design board. And I also check the board about the manufacture issues. I can't program the chip with the BDM. I just found the only one right now.
Are you using a usb multilink to programming or the cyclone? can you perform a mass erase?
Please let me know more information about the problem
have a good day
Thanks for your reply. I had tried to program the chip with S08 BDM ,and it can't connect to pc ,so it can't perform erase. I have no multilink or the cyclone.
Addtion: the chip work well in the manufacture room ,Maybe damaged when the product be installed to the truck. But we do not know what reason can cause the chip be damaged .When I replace the chip,it works stably and reliably.
Can you check if the BKGB pin has a low impedance or short, maybe it was damaged by an over-voltage or current.
