Hello, I have an 8308 using the fsl_elbc_nand NAND controller. I have chip selects 2 & 3 hooked up to a single die multiple chip select NAND chip. I have programmed u-boot and the kernel correctly and the NAND "chips" are found: NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 3,3V 8-bit) eLBC NAND device at 0xe0600000, bank 1 NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 3,3V 8-bit) eLBC NAND device at 0xe0608000, bank 2
The nand chips are correctly show up: # cat /proc/mtd dev: size erasesize name mtd0: 02000000 00020000 "fe000000.flash" mtd1: 40000000 00020000 "e0600000.flash" mtd2: 40000000 00020000 "e0608000.flash" (mtd0 is unrelated NOR part). I want to run UBIFS on the combined 2 gigs of flash. Whats the best way to do this? I tried using the mtdconcat stuff and wrote a small driver but I am not sure how to populate the mtd_info structure since do_probe_map doesn't work with NAND AFAIK. I see that fsl_elbc_select_chip says "hardware does not seem to support this". Not sure if this is related. I see some comments in mtd-physmap.txt about using multiple reg ranges? Does this work with NAND? Thanks for any pointers, Barry _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
