Re: [U-Boot] Can't erase or read NOR using mtd part-id
Hello, thanks for your reply. I'm running u-boot 1.3.1. I got it from STLinux. I will try to set CONFIG_JFFS2. But does it mean it will erase the partition using JFFS2 ? Will it support to read and write the environment settings with this file format ?
