CC2640R2F: CC2640R2F OSAL_SNV_WRITE AND READ PROBLEM

Can you elaborate how you do SNV write/read in your application?

hello Marie H,
Not yet sloved this problem .

Hi Mamatha,

Can you describe your problem in more detail?

Are you giving the correct length of the data to read?

Hello YiKai Chen,

sorry for late reply.

status_snv = osal_snv_write(0x81, strlen((char *)data1), data1);
status_snv = osal_snv_write(0x82, strlen((char *)data2), data2);
status_snv = osal_snv_write(0x83, strlen((char *)data3), data3);
status_snv = osal_snv_write(0x84, strlen((char *)data4), data4);

memset(test, 0, 50);
status_snv = osal_snv_read(0x81, 50, test);

this is my code. when i read 0x81 memory location in test buffer i am getting data1 and along with data1 getting data2 and data3.
In 0x81 memory location i stored only data1. data2 and data3 stored in different NVIDs. when i read 0x81 NVID why i am getting another NVID data also.

Hello Marie H ,

status_snv = osal_snv_write(0x81, strlen((char *)data1), data1);
status_snv = osal_snv_write(0x82, strlen((char *)data2), data2);
status_snv = osal_snv_write(0x83, strlen((char *)data3), data3);
status_snv = osal_snv_write(0x84, strlen((char *)data4), data4);

memset(test, 0, 50);
status_snv = osal_snv_read(0x81, 50, test);

Can you specify what’s inside data1-4?

data1 - ZCUXXX,B1234,A!@#$%
data2 - 23-01-2018
data3 - 24-01-2018
data4 - 987653

When you run your code, what do you get in test?

sorry previously i missed time in data2 and data3.
data2 - 23-01-2018-16:00:00
data3 - 24-01-2018-16:00:00

Can you set a breakpoint on "status_snv = osal_snv_read(0x81, 50, test);" and check what is in temp after your application does "memset(test, 0, 50);".

after execution of this instruction memset(test, 0 ,50); in test buffer all elements are zeros.

Hi mamatha,

I think you should set the exact length at osal_snv_read() for SNV ID 0x81. For exercise try the example osal_snv_write() and osal_snv_read() code from the docs.

Hi Mamatha,

Did you figure it out?

I will close this thread due to inactivity.
