Hi linux-mips,
We have AMD PB1000 and openpda platform and the hardhat linux keranl. csb350 is a new board,and we want to port the hardhat kernal to the csb350. But after we download the "hello world" ,which is comopiled with the mips-elf-gcc,to the ram 0xa0300000,then "call 0xa0300000",we got "Returned: -2147239488 (0x8003b9c0)" . we tftped the kernal image to the RAM 0xa0300000,then call it ,got the same result "Returned: -2147239488 (0x8003b9c0)" or it stopped there.
