Hello，

I am using the Safety Power System Basis Chip FS6523，the following is the circuit about it. Now it can't work and supply the voltages. I just use it to supply voltages while I am making it enter debug mode according to pulling up the DEBUG. Why is it? How can I solve it? Thanks for help.

Hello Minmin,

If you have an oscilloscope, could you post here a screenshot with Vsup, Vpre, Vcore and RSTB waveforms?

Also please share a list of initialization SPI commands.

Best regards,

Tomas
