Hello;
I am an almost a newbie on ARM/ I was trying to figure out how to configure a startup.s file. I worked on PLL settings a little and after that it started not to respond me. please note that I use different board and flash program (H-JTAG).
I have found that If I load a wrong pll settings , it won't respond me any longer until I load the correct settings manually.
Then, I tried to load correct setting via ISP. But whatever I have done , The micro doesn't enter the isp mode.
Thanks, Any help will be welcome

If JTAG can't run ISP mode, than run it by self.
LOW on P0.14 while RESET is LOW forces on-chip boot-loader to take control of the part after reset.
Than you can program with JTAG with no problem.
