I think it would. For me $bootargs_base also contained root= and
rootfstype= pointing at the flash which was giving the kernel some
confusion having them specified twice, so if you have problems with
it check that.
I'm thinking that the 0x32000000 might indicate an offset to where
the partition starts when you have an 8mb vfat partition first.
Should it be changed to 0x0?
No. 0x32000000 is the memory address the kernel will be loaded to.
So ext2load reads the file $sd_image_name into memory starting at
address 0x32000000. Then bootm 0x3200000 jumps there to start the
kernel running.
Cheers,
Alex
