Hi, all,
I use the gerber in the IPNC_RDK_GA_Release3.5.0 to reproduce the camera. I use the same part as the schematic. However, there are problems. When I just use the power board(dm812x_ipnc_pow_v0_96a_dec1), do not connect the other boards, all the voltage is ok. But when I connect the other boards, problem comes. The voltage SYS_3v3 and VCC_PWR turn to square wave, and its frequency is about 20KHz. I rechecked carefully, I am sure there are nothing wrong in other parts. and the other boards work right when I connect them to the Appro's power board.
Can you give me some advice? Is this the right place to ask for help? if not ,where should I to post it?
thank you!
Best regard,
Haitao
