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, KenLink Copied
