U-Boot "nand" issue

[jagadiswar_rao]

Hi Team,

we are using ls2088a custom board in which we are booting with QSPI.In u-boot not able to access NAND.we are currently compiling with ls2088ardb_qspi_defconfig.Attaching logs for same.

[Pavel]

There is the following information in the LS2088ARDB reference Manual:

When operating in QSPI mode, the IFC interface is non-functional, and access to the CPLD through IFC bus is disabled.

The QSPI NOR flash device is the Spansion S25FS512SAGNFI011 quad-SPI serial flash 64 Mbyte memory. The flash device is controlled with the dedicated QuadSPI controller, which replaces portions of the IFC interface.

See also attached file. It is board initialization file. This file is available using the following path in LSDK:

/packages/firmware/u-boot/board/freescale/ls2080ardb

Find the following:

/*

 * IFC and QSPI are muxed on board.

 * So disable IFC node in dts if QSPI is enabled or

 * disable QSPI node in dts in case QSPI is not enabled.

 */

Have a great day,
Pavel Chubakov

NXP SDK 2.0-1703 and LSDK 18.12 or LSDK 19.03 supports NAND on the LS2088A boards.

See dump from u-boot on the page 230 of SDK 2.0-1703 documentation:

https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

NXP LSDK supports NAND and supports booting from NAND Flash.

Check your u-boot setting.

Hi Pavel,

yes, It detecting in u-boot of NOR flash.But we need NAND detection in u-boot of  QSPI . As we are using LSDK 18.09.
