Hi,
I have two boards - a de0_nano_soc and a sockit. Neither works with a u-boot v2016.03 build. Is anybody out there using these eval boards able to successfully build & run u-boot? On both cards, the u-boot-with-spl.sfp (includes SPL, uboot.img, dtb all in one) I generate either doesn't boot at all, or boots sporadically, failing on memory calibration. Here is one example: U-Boot SPL 2016.03 (Mar 16 2016 - 08:27:20) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION FAILED drivers/ddr/altera/sequencer.c: Calibration complete SDRAM calibration failed. ### ERROR# ## Please RESET the board# ## U-Boot SPL 2016.03 (Mar 16 2016 - 08:27:20) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION FAILED drivers/ddr/altera/sequencer.c: Calibration complete SDRAM calibration failed. ### ERROR# ## Please RESET the board# ## U-Boot SPL 2016.03 (Mar 16 2016 - 08:27:20) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION PASSED drivers/ddr/altera/sequencer.c: Calibration complete Trying to boot from MMC U-Boot 2016.03 (Mar 16 2016 - 08:27:20 -0700) CPU: Altera SoCFPGA Platform FPGA: Altera Cyclone V, SE/A4 or SX/C4, version 0x0 BOOT: SD/MMC Internal Transceiver (3.0V) Watchdog enabled I2C: ready DRAM: 1 GiB MMC: dwmmc0@ff704000: 0 In: serial Out: serial Err: serial Model: Terasic DE0-Nano(Atlas) Net: Error: ethernet@ff702000 address not set.
