Hi All,
Now I am implementing DFU support on Atmel sama5d3xek board, when try
to download rootfs image to NAND flash through DFU, we need to drop
ffs from rootfs image.
Do you use ubi or jffs2?
I tested with both ubi and jffs2 in raw mode.
In dfu_nand.c when it call nand_write_skip_bad() with flags as 0.
However, I need to call nand_write_skip_bad() with flags at least with
WITH_DROP_FFS set.
Till now, I don't find any good solution to pass the parameter, except
hard code it or through "#ifdef CONFIG_CMD_NAND_TRIMFFS" to set it.
Any suggestions for it and any other solution?
There was a discussion, how to reorganize the dfu_alt_info var, see:
http://lists.denx.de/pipermail/u-boot/2013-July/158920.html
I think, your question fits into this thread ...
Currently, I think, you should add in
drivers/dfu/dfu_nand.c:dfu_fill_entity_nand()
a new "partdropffs" ? string, and set a marker like for "partubi"
the dfu->data.nand.ubi var, and use this marker, where you need it ...
OK, I will wait the final decision.
Maybe for raw and ubi both need this option.
bye,
Heiko
