I did a test, on mcu2_0 before loop ipc status flag 0x7, I wrote 0x5a5a5a5a to 0xa2100068, and read the address in remoteproc driver, it can get this value immediately, then I write 0x57575757 to 0xa2100068 in remoteproc driver, mcu2_0 can't get this value immediately. I call __flush_dcache_area() and barrier() in remoteproc drier, it's no impact.
how to make cache coherence when a72 write value to address?
Thanks!
