|Subject:||[Ltib] Booting from SDHC|
|Date:||Wed, 17 Nov 2010 09:37:37 -0500|
Has anyone booted the kernel from SDHC card?
I have 2.6.28 kernel built for Freescale MPC8536E and booting from NFS.
I would like to copy the kernel & file system over to SD card to eliminate NFS from my Ethernet traffic timing tests.
I have tried 2-4GB SDHC cars and they are pre-formatted with W95 FAT16 partitions.
I can mount the partition:
mount /dev/mmcblk0p1 /mnt/tmp/
But I can’t write to it.
I tried using fdisk to delete the partition and make a new linux partition; tried changing the FAT16 partition to linux partition.
But I can’t save the changes.
I was able to mount the drive:
mount /dev/mmcblk0 /mnt/tmp/
But I have less than 256MB to write to.
