Hello Large Page NAND block has 64 pages and Small Page NAND block has 32 pages. YAFFS uses the same value (YAFFS_PASSIVE_GC_CHUNKS=2) for Large Page NAND and Small Page NAND during the passive GC. I noticed that my system has the write performance problem due to using too many aggressive GC. If I change YAFFS_PASSIVE_GC_CHUNKS to 4 for Large Page NAND, will I have any side affect? Thanks, Chung
