5.1.9. Board Bring Up Considerations

This section describes the considerations that are useful for board bring up.

Reserved BSEL Setting

During initial stages of bringup, if a JTAG connection cannot be established to the target, it may be beneficial to set BSEL to 0x0 "Reserved" setting to prevent the Boot ROM from trying to boot from a specific boot source. Then a test program can be downloaded and ran with a debugger.

Bootloader UART Logging

On initial power on, if the device is in an unconfigured state, only the dedicated HPS I/O is available to the processor. To have visibility into the boot process before the other device I/O are configured, dedicated I/O must be used to connect to the serial interface.

GUIDELINE: Ensure that you have connected a UART serial interface to the dedicated I/O in the HPS device in order to get visibility into the boot process. This option is not available for NAND.
