[U-Boot] Unable to boot from QSPI (u-boot 2016.11-rc1)
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 - found match at 'generic_simple_bus' bind node dwmmc0@ff704000 - found match at 'socfpga_dwmmc' Bound device dwmmc0@ff704000 to soc bind node spi@ff705000 - found match at 'cadence_spi' bind node n25q00@0 No match for node 'n25q00@0' Bound device spi@ff705000 to soc Bound device soc to root_driver Trying to boot from SPI Bound device spi_flash to spi@ff705000 SF: Got idcodes 00000000x: x x x x x .!.D
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!
Hi,
Can you elaborate more on which file or function to look at? I am quite new to u-boot.

Try to boot with other boot sources(mmc or other) and 'sf probe' the flash on u-boot. this make sure no issue on with SPI controller or flash. otherwise need to check with cadence_spi_xfer.
thanks!

Can you please revert commit dac3bf20 and try again? Does it solve the problem?

Bingo! By reverting this commit, I could get pass the boot loop. And one more thing for those who use n25q00 QSPI, if you encounter "### ERROR ### Please RESET the board ###", remember to add "spi-flash" in your DTS compatible string.
