Hi all,
I have a custom board based on Altera Cyclone V SoC, when I tried to boot from QSPI, it stuck in a boot loop, I try to enable some debug message, and here it is:
U-Boot SPL 2016.09.01 (Oct 03 2016 - 18:14:42) drivers/ddr/altera/sequencer.c: Preparing to start memory calibration drivers/ddr/altera/sequencer.c: CALIBRATION PASSED drivers/ddr/altera/sequencer.c: Calibration complete bind node soc

u-boot from Altera working fine, but I plan to use the mainline u-boot. Any idea why it does not work?
Look like some controller init issue for getting RDID, try to probe in u-boot instead SPL.
thanks!
