Troubleshooting

If, after downloading your application into the dongle, the application doesn’t run:

●

Check the 91x_init.s file for the FMI configuration (it must be unused)

●

Check your system clock settings, keeping in mind that the clock is already running and

the situation is different with respect to a startup after hardware reset. In this case you

should follow the correct order for register re-configuration. For the first approach you

can comment this section and try your application without these settings. If it begins

working, then the clock settings are the root cause of the failure.
