Hi,

you may need to download the IMX53_1109_LINUXDOCS_BUNDLE, there you will look the the i.MX53_START_Linux_BSP_UserGuide.pdf where chapter 5, 6, 7 you can find the procedure to replace your uImage,

hopes this can help you.

I read that but it talks about if you create your own rootfs and uImage in one package,

I just wanted to replace the uImage from the sd card, I had done it from /boot but it still loads the old uImage.

Hi andrebella..

My mistake, is in chapter 8, see below, you can easy replace your uImage with a dd command from your linux box.

8.1.3 Copying the kernel image (pag 36)

The following command will copy the kernel image to the SD/MMC card

$ sudo dd if= uImage of=/dev/sdb bs=512 seek=2048 && sync && sync

This will copy the uImage to the media at offset 1MB.

just be very sure where your SD is located with the cat /proc/partitions is,

hope with this can find your solution.
