I have an issue in my retarget printf study
AXI master port have not any transfer when I change address to unaligned address
There is my C code
volatitle int *tube = (volatile int *)0xfc000000;
*tube = ch;
I change the address to 0xfc000001;
I not sure this usage is legal or not in Cortex-r8.
Or my C program has not recommended style.
Thank for your help!
Thank for your reply. I check our design SCTLR.A is zero.
I send two accesses One is normal access and the other is unaligned access.
Final only first access in my waveform
I think somthing is wrong in my program or design will auto mask not supported access
1. *(volatile int *) 0xfc000000 = 0xffff;
2. *(volatile int *) 0xfc000001 = 0xffffff00;
Thank you!
