Hello! I need help. Sorry fo my English. I have a board like a cubietrack. I try to use Micron 29F32G08CBADA I compiled mainline U-Boot 2017.09 and Linux kernel version 4.13.0 Nand is work in u-boot. But is not work in a linux kernel! I followed the directions by NAND_Howto I read many other information. when i try to any write operations in linux I get the input/output error: [root@alarm ~]# flash_erase /dev/mtd3 0 0 Erasing 2048 Kibyte @ 0 -- 167944 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 0 (mtd3) error 5 (Input/output error) flash_erase: error!: /dev/mtd3: MTD Erase failure error 5 (Input/output error) Erasing 2048 Kibyte @ b6faecb000000006 -- 167944 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 1 (m) error 5 (Input/output error) flash_erase: error!: /dev/mtd3: MTD Erase failure error 5 (Input/output error) Erasing 2048 Kibyte @ b6faecb00000000c -- 167944 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 2 (m) error 5 (Input/output error) flash_erase: error!: /dev/mtd3: MTD Erase failure error 5 (Input/output error) ...
