Hi all,
I am working in idt 79eb438 board(mips 4000 core), Os is linux(mips kernel), the board have a 4M flash, i want to use two partitions as fellow:
const struct cstm_mips_ixx_info cstm_mips_ixx_board_desc[PHYSMAP_NUMBER] =
{
{
"MTD flash", // name
0x11000000, //CONFIG_MTD_CSTM_MIPS_IXX_START, //
window_addr
0x400000, //CONFIG_MTD_CSTM_MIPS_IXX_LEN, // window_size
2, //CONFIG_MTD_CSTM_MIPS_IXX_BUSWIDTH, //
buswidth
2 // num_partitions
},
};
static struct mtd_partition
cstm_mips_ixx_partitions[PHYSMAP_NUMBER][MAX_PHYSMAP_PARTITIONS] = {
{
{
name: "main partition",
size: 0x200000,//CONFIG_MTD_CSTM_MIPS_IXX_LEN,
offset: 0,
},
{
name: "cramfs partition" ,
size: 0x200000 ,
offset: 0x200000 ,
},
},
};
but the system have some erros!
