I have designed one pcb according to ICETEK-OMAP3530-Mini. My tps65930 IC works correctly,and voltage output clk output all are right.26M and 32.768KHZ all are output. My question is that omap3530 does not have any information output throw UART. OR any information output throw JATG. I can not detect the omap3530 throw JTAG. The feedback information is it has a dead-clock . so I think omap3530 does not work correctly. And SYS_CLKREQ LINK to tps65930's CLKREQ have no singal output , it detect low voltage. OMAP'S SYS_OFF_MODE link to tps65930's NSLEEP1 IS detected low . These two pins are high voltage when the omap3530 works correct according to the datasheet manul. I donot know how to change my shcimatic in order to make my omap3530dcus to work correctly.. thanks for your help. my email is 2006yxb@163.com

as the datasheet says: the first fourth signals are all served, but sys_off_mode signal has no changes from low to high ,it is always low. I don't konw why
