Hi,
I'm using a micro2440 with default rootfs, bootloader and kernel recompiled
by me to use any GPIO pin. I want to use the board to send/receive messages
to another uC connected using 2 pins. The available pins I've found:
EINT 13 - data
EINT 14 - clock
The problem begins when the other uC start to send data through the EINT13
while at the same time I'm turning on the micro2440.
Supervivi use any EINT from ARM to boot?
How could I deactivate this pin check from supervivi?
The problem happens when the following sequence is executed:
1. Turn on uC
2. uC starts to send data without stop
3. Turn on ARM
Crash:
