5.1.9. Board Bring Up Considerations
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.
