Dear sir,
I am using AM3352 processor and got the SDK with version (PROCESSOR-SDK-LINUX-AM335X Ver.8.2.0.24).
In my program I want to check sdram set on my board when booting up linux, so I just wrote code at SPL like that showed below.
Ex.
*(int*)(0x80000000) = 1 ; /* sdram address */
/* do something to flush data to memory from the cache, */
/* and set invalidate to guarantee data read from memory. */
a = *(int*)(0x80000000) ; /* read data from memory */
if ( a != 1 ){
/* bad memory */
}
My question is that:
In SPL process, which function can I use to guarantee the data be written to main memory (dram), and read from it, but not the CPU cached data ?
regards
Xitong Zhang
