Boot processes
After the BIOS or U-Boot hardware verifications, POST tests run to verify the CPU and memory prior to booting the system software.
After POST testing, there are three additional types of diagnostic tools you can use for testing your system.
•
Manual diagnostic boot process — To run additional testing, manually download and run the EDA tool. The EDA tool reports and logs
pass/fail results.
•
ONIE with EDA — EDA is installed; you do not have to manually download the tool. Select the diagnostic option at boot-up. You can
run this tool without a management interface.
•
Autorun EDA — EDA is installed; you do not have to manually download the tool. Select the diagnostic option at boot-up. You can run
this tool without a management interface. The system always launches EDA in Quick Test mode to verify the hardware components
before loading the software. If there is a failure at boot-up, based on the EDA configuration, the software may or may not continue the
boot process.
POST
POST diagnostics verifies system memory before the software loads. Test configuration parameters are saved in CMOS for the next boot-
up.
EDA, Quick Test Mode
Quick Test mode runs basic device access tests for the system hardware to verify that the device is active and responding.
In Quick Test mode, the EDA tool quickly tests if the hardware components are accessible. It confirms that the components respond to
read access and in some cases, simple write access. Tests are read-only and non-destructive (except the memtool command, which does
allow read/write operations).
