What SW do you run on CC2530? Is it Z-Stack?

In Z-Stack, you would use osal_nv_write to write information into flash and NV ID 0x0401-0x0FFF are reserved for application usage.

I use osal_nv_write(0x401, 0, 1, &payload);

where payload is the array of data payload[64]

but i didn't get any thing by writing data into memory and reading it.

for reading purpose I used osal_nv_read(0x401, 0, 1, &buff); where buff[64].

Please help me to resolve this...

The following code is an example to write/read a byte on NV

uint8 nv_test=0x78;

uint16 nv_test_id=0x0401;

osal_nv_item_init(nv_test_id, 1, NULL);

osal_nv_write(nv_test_id, 0, 1, &nv_test);

osal_nv_read(nv_test_id, 0, 1, &nv_test);
