LPC17xx can't enter ISP mode

Adam Kleczko

Hi,
I got this problem with my LPC1768. I was working on my project and tried to use PLL, but I set to big MSel and my LPC is not responding now. I'm programing through JTAG with H-Jtag but it reads only signature of uC and nothing else. I tried to enter ISP mode but it seems not to go into. I put line 2.10 low and reset but flash magic and lpc21isp don't get respond from it. I'm sure I using good lines and UART0. Can anybody help?

    It's possible I've done it when everything was working. You just have to check in keil "Make hex file" then you going in to H-JTAG Flasher and you send the code to board. After that you have to click debug and reset debuging and uC. It's not working to great and it often make some small troubles but it's working.
