Boot C5 HPS from SD card

I try to boot C5 HPS from a SD card. I get the following information from UART0 

 

----------------------------------------------------------------------- 

U-Boot SPL 2013.01.01 (Oct 23 2017 - 14:37:32) 

 

BOARD : Altera SOCFPGA Cyclone V Board 

SDRAM: Initializing MMR registers 

SDRAM: Calibrating PHY 

SEQ.C: Preparing to start memory calibration 

 

SEQ.C: CALIBRATION PASSED 

ALTERA DWMMC: 0 

 

spl: mmc init failed: err - -1 

 

### ERROR# ## Please RESET the board# ## 

 

------------------------------------------------------------ 

 

1. Is it in the "SPL" booting step and failed?  

2. My SPL & uboot is saved in SD card. If the SPL is runing, can I say my SD card is ok? 

3. I get a priodic goes low pulse on warm reset pin. (frequency is about 1.34s, pulse width is about 0.5ms) 

4. JTAG can not find HPS. (FPGA can be configured by JTAG) May my FPGA chip is not soldering well? 

 

thank you for your reading & any reply, 

 

sincerely, 

Ken
