Hi
We found the issue when using floating-point calculations in the mulitple ISR, then the floating-point number will be not as expected sometimes.
After adding "VPUSH {D0-D15}" in the beginning of the interrupt callback and adding "VPOP {D0-D15}" in the end of the interrupt callback, the issue will not occur anymore.
I think the cause is the floating-point register set is not automatically saved and restored for Cortex-R52+, is that right ?
What is the suggestion for such issue ?
Is it necessary to pop and push FPSCR manually ?
BR, Grace
