I have some curious things about I.MX Bootloader.
I know that I.MX28 have secondary bootloader area which is used when primary boot fail.
My bootloader area is saved at 0x10000. And secondary is in 0x20000.
I did some experiment. I removed flash from 0x10000 to 0x30000.(I think here is bootloader area.)
After remove flash, its bootloader working properly. It is very strange. I think, it should fail. Because i remove bootloader area. But, it working well.
So my hypothesis is that I.MX28 have bootloader backup area. But i'm not sure. Do you have idea of this?
When i removed flash area form 0x00000 to 0x30000, the bootloader is not working.
Anyone who knows about this, please let me know.
