TMS570LS1224: jumping to abort when a variable length array is executed as shown.

Part Number: TMS570LS1224

hi,

i have defined an array as : uint8_t list_array[size]; in a function.

when this line gets executed, the control is jumping to exit. c file and suspends the program execution.

how to use variable length arrays?

Hi Vidya,

In C language, you cannot vary the size of the array in runtime. The array size will be fixed at compile stage only.

If you want to create a dynamic array (i.e. you want to change the size in runtime), then you should use linked lists.

Hi,

variable length arrays is an additional feature from C99 Standard.

I guess this feature is present in the compiler of CCS, since it hasn't resulted any compiler error when i have defined this array.

even in debug mode, it didn't result any error instead jumped to an abort function which is inbuilt in this SDK.

I would like to know more about loader_exit and abort function which i have attached previously.

Please go through the below link.
