Hi, I'm working on a series of patches, to support 8k nand page in atmel_nand driver. Currently, I can detect the nand and handle an oob size of 448. But i have a problem with the pmecc, when barebox tried to perform pmecc operation, I get the following message: PMECC: Timeout to calculate error location. Example of log: nand: NAND device: Manufacturer ID: 0x2c, Chip ID: 0x68 (Micron MT29F32G08ABAAAWP), 4096MiB, page size: 8192, OOB size: 448 atmel_nand atmel_nand0: Initialize PMECC params, cap: 8, sector: 1024 atmel_nand atmel_nand0: PMECC: Timeout to calculate error location. atmel_nand atmel_nand0: PMECC: Timeout to calculate error location. atmel_nand atmel_nand0: PMECC: Timeout to calculate error location. atmel_nand atmel_nand0: PMECC: Timeout to calculate error location.

Someone have an idea ? Best regards, Raphaël _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
