Introduction
The firmware validation process is described in the "2nd Stage Boot Loader" manual (see Revision 17 / Chapter 4.4.).
Before a NXF file is started, the 2nd Stage Loader verifies the file header information againts the content in the security memory or Flash Device Label (FDL).
If the information does not match, the firmware file won't be started and a corresponding error information willbe inserted into the boot loader error variable ulBootError.
Firmware Validation Points
- Manufacturer
- DeviceClass
- HwCompatibility
