Dear All,

              i have a customer download code to Nandflash, but there is only one linux.sb, athough it include two files uboot.sb and uImage,

but when it boot up, i can't access to the uboot console, so is there a ucl.xml script can download uboot.sb and uImage alonely on the Nandflash.

Best Regards,

[igorpadykov]

Hi John

Freescale BSP (below) supports only two bootstreams (linux.sb, uboot.sb)

other configurations are not supported

i.MX28 Evaluation Kit|Freescale

I am not aware of efforts supporting "download uboot.sb and uImage"

with NAND, seems this can be supported only with NFS.

Actually for such task one needs to add NAND support to i.MX28 Uboot, which

could be not-trivial.

Best regards

igor

hi,

     but if i use the official config on Nandflash, how can i enter the uboot console?

Best Regards,

[igorpadykov]

with nand you can boot linux.sb or uboot.sb.
