Hi Experts,

I want to write on INFOB and INFOA memory but I'm not getting how to write saw examples codes but failed. I want to write like this

#pragma location="INFOB"
const st_rf_config stRfConfig_bkup =
{
    .node_id = UNPAIRED_NODE_ID,
    .network_addr = UNPAIRED_NETWORK_ADDR,
//    .status = PAIRED_MODE,
    .status = UNPAIRED_MODE,
    .node_slot = 0,
};
 

Can anyone help me how to do that because I didn't found any support.......
