interrupt problems that the code stops at a certain line

Other Parts Discussed in Thread: HALCOGEN

I want to use the ultrasonic device.

At first I set a RTI timer which will interrupt every 100ms, in which I will output high level in GIOA[6] to trigger the ultrasonic device.

And I set a rising edge interrupt in the GIOA[7] to capture the high level echo time of the device.

However, the program will stop at a certain part and be stuck there. It is

dataEntry
b dataEntry

in "HL_sys_intvece.asm"

It really confuses me.

The code attachs.

The configuration in the HALCOGEN is mainly as the picture attached. And the RTIcompare0, GIO high, GIO low interrupt are enabled to be IRQ8666.temp12.c

Sorry forget to attach the configuration picture.

Your program has stopped at the Data Abort exception. Look at the link register (LR_abt) to see the address of the program counter (PC) when the abort was taken. You can read about data aborts in the Cortex R5 Technical Reference Manual from ARM LINK. Look for a read or write to an unimplemented memory location (such as using an uninitialized pointer) or reading from a location with ECC or parity and the ECC or parity was not initialized.

Thank you very much for your guidance. I will go for a try and look for the problem.
