Hi David,
I was exploring the ways to add partition into the blob dynamically.
I followd the following steps.
1) say we have 5 partitions. Flash size is 128mb
norflash at 0,0{
1----------
2------------------
3
----
5
partition at f80000 {
label = "u_booot";
reg = <0xf80000 0x60000>;
};
2) i am trying to add 6th partition dynamically in uboot.
I used the the nodeoffset of norflash at 0,0 which is parent offset wher i
want to create 6th partiton. I passed this parent offset to
ret = fdt_add_subnode(blob,nodeoffset, "partition at 6800000");
nodeoffset = ret;
ptr[0] = 0x6800000;
ptr[1] = 0x800000;
offset = 0x6800000;
regs[0] += size_delta;
memcpy(regs, ptr, plen);
ret = fdt_setprop(blob, nodeoffset, "reg", regs, plen);
I am printing the the blob later. i see that node is created but the last
partition ie u-boot @ f80000 is going away.
the blob size is 8000 byes which we built using the
dtc -S 8000 -R 7 -I dts -O dtb -o file.dtb file.dts
Let me know if we need to increase size of the blob or something which i m
missing.
This is going to help a lot if you can reply.
