1.7.5. HPS Boot Loader Debugging

In cases where a debugger connection is not available, and the HPS is booting from flash, flash device signals should be monitored. Please refer to the "Boot Flash Device Issues" section.

Using a debugger is most effective for debugging the boot loader execution because it can access the source code. The following general-purpose debugging techniques can be used:

  • On systems with a JTAG connection, use a debugger to step through boot loader's execution.
  • Alternatively, the boot loader code can be modified to provide more useful debug information through hardware resources such as LEDs, UART, or writing to an unused memory location.
