I'm using am5728 gpio and I have got a problem.
when I set GPIO2_4 's direction register as output in C66xx but not in Cortex-A15,sometimes it work good ， and sometimes it does not work, I use memtool to get the physical address 0x48055134 in linux:
Reading 0x1 count starting at address 0x48055134
reading mem… add:0xb6f15134 count:0x1 size:0x4
I found GPIO2_4's output is disable!!! what's the problem?
1，please check cache on dsp side, you may do cache wb after set register.
2, you can use ccs /jtag tools to do the debug
