Enum tock_tbf::types::InitialTbfParseError

pub enum InitialTbfParseError {
    UnableToParse,
    InvalidHeader(u32),
}

Error when parsing just the beginning of the TBF header. This is only used when establishing the linked list structure of apps installed in flash.

Variants

UnableToParse

We were unable to parse the beginning of the header. This either means we ran out of flash, or the trusted values are invalid meaning this is just empty flash after the end of the last app. This error is fine, as it just means we must have hit the end of the linked list of apps.

InvalidHeader(u32)

Some length or value in the header is invalid. The header parsing has failed at this point. However, the total app length value is a trusted field, so we return that value with this error so that we can skip over this invalid app and continue to check for additional apps.
