I feel very strange, I have encountered this problem twice on different circuit boards, has no one else encountered it?
In addition, when it stops at tag initialized, I press the reset button, it will restart but it also stops at tag initialized
I found that VCC_RTC is only 0.53v. We changed a supercapacitor with industrial temperature 470000uF
Can we borrow JTAG from NVIDIA , we want to know the status of the CPU
I get the solution， the about change Q513 need to change C543 and R559 not only change C543
