side effects here. Reading NAND now fails on my BeagleBoard. Regardless if I use gcc 4.3.5 or gcc 4.5.1, after applying that patch the wrong ID of the NAND is read. In nand_get_flash_type() (drivers/mtd/nand/nand_base.c) without that patch I will get the following:
*maf_id: 44, dev_id: 186
with the patch the following is read:
*maf_id: 128, dev_id: 85
The nand_get_flash_type routine reads these id's twice and compares them. Do your see an error message like this?
second ID read did not match
Which just is wrong.
I haven't looked further up to now, maybe thats just a side effect of some wrong clock settings because of different timings through those barrieres or whatever.
