Struct lpc55::protected_flash::CustomerSettingsArea

pub struct CustomerSettingsArea<CustomerData = RawCustomerData, VendorUsage = RawVendorUsage>where
    CustomerData: CustomerSettingsCustomerData,
    VendorUsage: CustomerSettingsVendorUsage,{
    pub scratch: CustomerSettings<CustomerData, VendorUsage>,
    pub ping: CustomerSettings<CustomerData, VendorUsage>,
    pub pong: CustomerSettings<CustomerData, VendorUsage>,
}

This is a bit of an interesting construction.

The scratch page “remains outside the protected region”, the intent is that the application updates this (in NXP’s view, by calling bootloader API), and then resets the core.

During startup, bootloader selects one of ping or pong page, depending on which has higher “version” field. If scratch page has even higher “version”, the bootloader erases the older of ping/pong and overwrites with scratch.

Fields

scratch: CustomerSettings<CustomerData, VendorUsage>

ping: CustomerSettings<CustomerData, VendorUsage>

pong: CustomerSettings<CustomerData, VendorUsage>
