How to solve the problem of loading wrong pll settings?

[RF_man]

Hello;

I am almost a newbie on Arm micros. I have a lpc2132 board and yesterday I accidentally loaded a wrong pll setting. After that, my jtag device refused to connect the micro. I heard that jtag didn't connect if I use a wrong pll setting and I had to load correct one manually.

The problem is that I dont know how to connect the microcontroller manually.

Any help will be welcome!!

Thanks

what happens if i use wrong pll

Hi

You will need to erase the micro flash using serial communication and a pc program like the FLASH MAGIC

then you will gain control via JTAG again


All the best
