2.3. Factory Image Boot
The purpose of the factory image is to provide enough functionality to allow a device whose application images have all been corrupted (or replaced with broken application images) to obtain a new application image and program that image into QSPI.
Once the factory image is loaded, new application images could be programmed in QSPI to replace the failed ones, from either U-Boot or Linux.
- You assign the function LOADFACTORY to an SDM pin and assert the pin soon after a POR or nCONFIG release.
- All SDM attempts to load the application images fail.
- You request the factory image to be loaded.
- Decision firmware detects that the decision firmware data is corrupted.
- Decision firmware detects that both CPBs are corrupted.
When loading the factory image, the configuration system treats it in the same way as it does an application image.
