imx6Solo/DL NAND BOOT without kobs-ng and no linux kernel

[jaynedickinson]

Greetings

I am trying to boot a custom imx6Solo board from NAND , I don't have a linux kernel running yet ... so I am modifying

u-boot 2013.04 tools/mxsboot.c to properly setup the 4 FCB blocks, 4 DBBT blocks, and boot data ( 1024 spare data , IVT, boot_app, DCD )

I can boot using the imx_usb tool ( serial downloader )

I am using a SPANSION S34ML02G1 NAND chip ( 256Mbytes ) with the GPMI interface for the iMX6Solo processor.

I've included my DCD table , my configs, my u-boot board init

I've confirmed the CCM clock settings

I've confirmed some of the NAND settings with Spansion ( I'm still trying to get more information in case the preamble delays are incorrect

I can run u-boot after the imx_usb transfers the u-boot.fcb , I can read and write back to NAND without issue

So I am wondering what other magic sauce I need... anyone done this without kobs_ng ,

Eventually I will be running Freescale's Yocto 3.10.17-1.0.0_beta with my mods...

I got my u-boot from the Freescale Yocto 3.10.17-1.0.0_beta ... wondering if I need to use u-boot 2013.10 since I've seen multiple

updates for the drivers/mtd/nand/mxs_nand.c driver... hmmm

Any help would be most appreciated.

Hello Jayne,

I'm using imx6 based custom board with the same NAND chip. I'm loading u-boot, kernel and rootfs to SDRAM using imx_usb tool, partitioning NAND as MTD device, writing JFFS2 rootfs to a specific rootfs partition and booting kernel by jumping to its location in memory. Kernel is configured to mount JFFS2 from /dev/mtdblockN device where N is a partition ID.

What do you want to achieve? How do you envision your device to be booted?

Regards,

Konstantyn
