Is this the default Altera layout ?
Yah but believe it need to be updated
So you're not worried about compatibility I presume ?
+#define MTDPARTS_DEFAULT "mtdparts=ff705000.spi:"\
"256k(spl)," \"64k(env)," \"64k(dtb)," \What happens if the DT grows over 64k ?
Hmmm rethinking of this, I will make Linux dtb, U-Boot and kernel as part of one big UBI partition called boot.
I am using this sort of layout on SoCkit internally:
"mtdparts=ff705000.spi:" \ "1m(u-boot)," \ "64k(env1)," \ "64k(env2)," \ "-(UBI)\0"
I have two environment blocks to implement redundant env, which is useful when deploying the system. It makes the system slightly more resilient against problems of aging flash.
"256k(boot)," \256k is not enough for U-Boot (considering this is U-Boot).
Will create boot region to avoid worrying the size issue
"16m(kernel)," \"16m(rootfs)," \Why don't you put kernel and rootfs onto the UBI volume instead ?
Yup, kernel will go into boot partition. It will be separated from rootfs as user might choose nfs.
Can you share the final layout before you roll out patches ?
