We got a boot up problem.
Our project use the LPC1820FBD144, the power source from USB VBUS.
I take USB cable plug in and plug out repeatedly.
Or press the reset button repeatedly
It sometime will boot up fail.
The failure rate is 1~2 / 10 time.
Is that Known Issue?
Because of I found the documents " LPC18XX-RN.pdf "
It mentions the similar problem.
" In a few hundred reset cycles one cycle might fail with a Hard Fault right after PLL initialization code "
If it is this known issue, how can we do?
If anyone meet the same problem.
If anyone has solution can resolve it.
