I am debugging my board based on S32R274 now, but I can encountered a problem: my PE micro USB mulitlink can not connect my device.
After checking the JTAG interface signals, I found that the the signal on S32R274 RESET_B pin always keep in LOW after I power on the system(either with or without the JTAG interface connected). And actually, the pin is pull-up to V3.3 by a 4.7K resistor.
An in S32R274 reference manual Table4-1, it is described that the RESET_B is kept in LOW during POR and RESET stages. It means that my S32R274 is kept in POR/RESET stage, and there is some problem with my S32R274?
Is there anybody can tell me how can I get throught the problem? Thanks
