Hi, I use Coreboot with u-boot-x86 as payload to bring-up my Intel Atom C2000 platform, but I cannot make my SPI flash(w25q128fv) to work. Actually the SPI was detected under coreboot with correct ID, but in u-boot “sf probe” command, it just always failed. After tracing and code dump, I found it was failed due to SPIS_FCERR in spi/ich.c spi_xfer function. I totally have no idea why this happened and how to proceed my bring-up. My u-boot-x86 is up-to-date version and the SPI use intel,ich9-spi compatible in my dts file.
Following is my dm tree and there is spi-flash device => dm tree Class Probed Name ---------------------------------------- root [ + ] root_driver serial [ + ] |-- serial keyboard [ + ] |-- keyboard rtc [ ] |-- rtc timer [ + ] |-- tsc-timer pci [ + ] `-- pci pch [ + ] |-- pch@1f,0 irq [ + ] | |-- irq-router spi [ ] | `-- spi spi_flash [ ] | `-- spi-flash@0 pci_generic [ ] |-- pci_0:0.0 pci [ + ] |-- pci_0:1.0 pci_generic [ ] | `-- pci_1:0.0 pci [ + ] |-- pci_0:3.0 pci_generic [ ] |-- pci_0:e.0 pci_generic [ ] |-- pci_0:f.0 pci_generic [ ] |-- pci_0:13.0 usb [ ] |-- ehci_pci pci_generic [ ] |-- pci_0:17.0 pci_generic [ ] |-- pci_0:18.0 pci_generic [ ] `-- pci_0:1f.3 => Could you please give me some hint or tell me where I can reference?
