nand writing is available for boot image in iMX6?

[hyun-moyang]

Hi,

I want to write the boot image in i.MX6 to use console window as below,

"reload_uboot=tftpboot u-boot.bin; nand erase 0x0 0x40000; nand write 0x10800000 0x0 0x40000"

When i download the uboot image to use above command, nand writing is OK , but when it is rebooting, downloaded image is not applicable.

Is there another command for downloading the uboot image?

please let me know

Regards

HM

Hi Hyun-mo

for bootable image one needs MFG Tool, it uses kobs-ng for

writing boot parameters to NAND.You can find these commands in

ucl2.xml (check for Sabre AI profile)

IMX_6DQ_MFG_TOOL : Tool and documentation for downloading OS images

Sabre AI supports NAND boot, one can check details in L3.0.35_4.1.0_LINUX_DOCS

SABRE for Automotive Infotainment Based on th|Freescale

Hi igor,

The First , I already writed the boot image to use MFG tool. And then, i want to write the boot image to use console window.

So, I writed the boot image to use the below command ,

"reload_uboot=tftpboot u-boot.bin; nand erase 0x0 0x40000; nand write 0x10800000 0x0 0x40000"

Boot image is not applicable in i.MX6 AI PDK.

I already review the documents, i.MX_6Dual6Quad_Sabre-AI_Linux_User's_Guide.pdf.

But i can't find how to download the boot image to use console window.

If you know it, please let me know.

Hi Igor,

is boot image written with MFG tool working (boots) ?

==>(Answer) right.

I checked your provided URL.

I have to use the 2013.10 u-boot version for writing the boot image to use console window.

Is it right?

Thanks

Yes, as answered on that link by BSP experts:

"The 3.10.9-1.0.0 alpha release supports NAND boot"

So please use it.
