Struct ConfigurationBlock

#[repr(C, packed(1))]
pub struct ConfigurationBlock { /* private fields */ }

A serial NOR configuration block

This is the memory that you’ll need to properly place in memory in order to boot your i.MX RT system. Consider keeping the symbol name, and specifying a link section, so that you can more easily place the memory in your linker script.

Unless otherwise specified, all unset fields are set to a bitpattern of zero.

1170 notes

By default, isUniformBlockSize is set to 1, indicating that the block size and sector sizes are equal. Using block_size clears this field and allows you to differentiate the block size from the sector size.
