I like to program all the corner cases.

I meant the dataRAM spare area: 8010h - 804fh in the bufferRAM address map.

After a load error, will this:

		this->read_bufferram(mtd, ONENAND_SPARERAM, buf, column, thislen);

read the what was meant to be loaded, or will it still contain the data from a previous load?

=> It depends on load error timings. but we think it is always invalid.
load error means that there's error during load from nand core to bufferram.

Thank you,
