I have made a board with I.MX6solox. Signal has not been detected on CLK of SD, CLK of SPI after power on. And no activity has been found on DN & DP of USB ether.

PC pointer can be read with trace32 after power on, But the value of PC are always 286C,286A. several registers has been read by JTAG, but the value seems correct.

Is there anyone who can help me?


我用IMX6solox 做了块板子。但上电后SD的CLK、SPI的CLK均没有发现任何信号,USB的DP、DN也没有发现任何信号。
