Reading from NVRAM in MTK2503D

jawadi

Hi. I am writing data to NVRAM using the non-blocking function mmi_frm_write_async_record and it works. But when using WriteRecord or ReadRecord, the operation cannot be done.

1. char word1[15];
   
2. S16 error;
   
3. //WriteRecord(NVRAM_BABT_T1, 1, "First", 6, &error);
   
4. mmi_frm_write_async_record(NVRAM_BABT_T1, 1, "hello", 6);
   
5. ReadRecord(NVRAM_BABT_T1, 1, word1, 6, &error );

Looks like the external queue is empty and it waits for the ILM message. Should I do something before calling ReadRecord?

Read nvram data and refer to this information

Thanks. I tried it in heartbeat_start and it worked, but it hangs and restarts when I try to use it in nm_gprs_cmd.c. Why is that? Is some form of initialization required?
