Hello.

I want to start application from User Flash memory.

I must connect BOOT_0 pin to log. 0............. OK

But, is it possible to connect BOOT1 pin to log. 0, too ?

In datasheet's table it is state ''X'' for BOOT_1 pin and log.0 for BOOT0_0 pin.

What ''X'' mean ?

1. Unconnected float pin (Hi-Z)

or

2. donÂ´t care (log.1 or log.0)

Is it possible to run application from User Flash memory with this configuration: BOOT_0 = log. 0, BOOT_1 = log.0 ?

Thanks
