CC3220SF-LAUNCHXL: atoll() question

Leo Choi1

I want to covert a string to a unsigned 64bit using atoll(), but the coverted value is incorrect.
For below examples, only string 3 is correct. The coverted value of string 1 and string has filled FF instead of 00.

uint64_t string1value,string2value,string3value;

char string1[]= "188900977659375"; //0x0000ABCDEFABCDEF
char string2[]= "2882400171"; //0x00000000ABCDEFAB
char string3[]= "11259375"; //0x0000000000ABCDEF

string1value = (uint64_t) atoll(string1);
string2value = (uint64_t) atoll(string2);
string3value = (uint64_t) atoll(string3);

Hi Leo,

I was not able to reproduce your issue. See below image, only difference is I used volatile to force the compiler to allow me to show the variables in the debugger. Can you please post your SDK version and CCS version? Are you working with an example project from the SDK?

If you do not have the latest SDK and CCS versions, can you try updating them? I am using the "empty" project from TI Drivers with TIRTOS (not TIRTOS7).

Have you included stdlib.h?

Hi Sabeeh

I am using SDK 5_10_00_02 and CCS 10.3.0.00007.

It looks like the function is nested too deep.
I tried to put the same code into different areas of the project. The code works at mainThread().

Those codes is put into a function nested two level below tcpWorkers function

tcpWorker()
|-----------praseACKCommand()
|----------third_Level_function()

If the same code are put into tcpWorker() and praseACKCommand(), then it works well. See screenshot A
