No, I think at this point you're into the stuff that
you need to think about yourself, ie what exactly
you want fault injection to do.

Thanks Peter.
I have made a program to read a string from the UART, then write it again
to the UART.
I made a function to manipulate values in the pl011 registers (bit flipping
the flags inside the registers).
The target is to simulate hardware fault injection.
For each run of the program, I made

No, they don't have any effect. (In this UART model we don't implement

Hello Peter,
I have one more simple question please.
Do the emulated baud rate registers have any effect? (I think they would
have no effect, because there is no real clock that can be used to produce
the baud rate).

Thank you very much Peter.
I will check the documentation for VersatilePB and ARM926EJ-S for more
understanding of interrupts handling.

The source code is it.
Note that the pl011 is only a UART. It is
Thanks Peter for your help.
Are there any documentation or source of information, that can describe how
interrupts are implemented, and how to use them (where is the vector table
to put the ISR ... etc) ?
In addition, any source of info that describes the code workflow when
reading or writing to t

Yes, we implement interrupts.
Hello all,
I have 2 problems regarding UART (pl011) in the emulated board VersatilePB.
(I am using *QEMU version 2.8.1.*)
*My main goal is*:
Disturbing the UART registers (such UARTCR, UARTLCR_H ... etc) in order to
simulate hardware faults (which can make bit flips in the hardware
registers thro
