Hi, I am able to boot DM355 based board from SD card. But if I create partitions in SD, partition information is written in block 0 of SD card and RBL expects UBL descriptor information from block 0. Hence I am not able to use SD card with partitions as bootable device.

Hi, It's not possible to boot directly from SD for DM6446. The RBL only understands UART, NAND and NOR boot modes. (You can do this for DM355) You can always write SD driver in UBL and then boot from it. Regarding partitions, you create partitions on SD as you would create for any other IDE or storage drive. You can then use "dd" command to write kernel and in u-boot (or ubl), parse partition table, and read the kernel image Thanks --- On Tue, 12/16/08, jitendraj...@emerson.com <jitendraj...@emerson.com> wrote: > From: jitendraj...@emerson.com <jitendraj...@emerson.com> > Subject: RE: Boot DM6446 from SD? > To: jo...@imsar.com, davinci-linux-open-source@linux.davincidsp.com > Date: Tuesday, December 16, 2008, 8:05 PM > Hi Josh, > > Are you successfully able to boot the OMAP based board from > SD card? > > Is the SD card formatted with any file system? > > How are you loading first stage loader and kernel image in > SD card? > > > > Regards, > > Jitendra > > > > ________________________________ > > From: > davinci-linux-open-source-bounces+jitendrajain=emerson....@linux.davinci > dsp.com > [mailto:davinci-linux-open-source-bounces+jitendrajain=emerson....@linux > .davincidsp.com] On Behalf Of Joshua Hintze > Sent: Tuesday, December 16, 2008 9:32 PM > To: davinci-linux-open-source@linux.davincidsp.com > Subject: Boot DM6446 from SD? > > > > Has anybody successfully gotten the DM6446 to boot from an > SD card?
