You can always do this after generating u-boot. The rules here are to generate the u-boot.imx. Then the same image can be stored at different addresses. Depending on the i.MX SOC, ofssets can be different (MX5 / MX6 have different offsets for NOR / NAND / oneNAND). Best regards, Stefano Babic

You can always do this after generating u-boot. Older U-Boot (from FreeScale) made an .imx image with 1KB padding which I could flash directly into the NAND at offset 0. Now I had to do manually that dd-magic (before I put it in Makefile) because openocd doesn't allow to flash at offset 0x400 (it demands write-page alignment). > The rules here are to generate the u-boot.imx.

I prefer a build system which generates an image ready for flashing but perhaps I have to do that outside of U-Boot, somehow. -- Timo

.imx image directly from mkimage must be flashed at offset 0x400 into the nand. Thats a little hard with e.g. openocd. Signed-off-by: Timo Ketola <timo@exertus.fi> --- Makefile | 3 +++ 1 files changed, 3 insertions(+), 0 deletions(-)
