Re: Failed to create MTD partitions

[Jupiter <jupiter.hce@gmail.com>]

Hello,

There is another statement before the device found, is the Error
setting BCH geometry : -22 caused by ECC or by invalid JEDEC? It is
kernel version 4.19 on iMX6ULZ MCU.

[    8.130891] nand: Could not find valid JEDEC parameter page; aborting
[    8.137591] nand: device found, Manufacturer ID: 0xec, Chip ID: 0xda
[    8.144246] nand: Samsung NAND 256MiB 3,3V 8-bit
[    8.148995] nand: 256 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB siz
e: 64
[    8.158330] gpmi-nand 1806000.gpmi-nand: Error setting BCH geometry : -22
[    8.166690] gpmi-nand: probe of 1806000.gpmi-nand failed with error -22

Thank you.

Kind regards,
